MODES FOR carrying out the INVENTION

[0034] Now, with reference to the accompanying drawings will be described preferred embodiments of in accordance with the wireless transmission system of the present invention. Although in the following description HDMI Multimedia Interface (High-Definition) - CEC (Consumer Electronics) is illustrated only as an example, a wired interface, this is not a limitation and, for example, is also applicable to wired interface such as IEEE 1394.

[0035] Figure 1 is a structural diagram of example devices-repeater, which is the wireless transmission system of the present invention, and in figure 1 the device is a repeater (hereinafter device type bridge) is designated as 1. Device type 1 bridge includes: unit 11 a wired connection for a communication connection to a wired (HDMI) device; unit 12 that controls the device 1 type bridge; unit 13 of the wireless connection for a communication connection to the wireless device; driver 14 HDMI-CEC, which transmits/receives the CEC message, which is when the leader wired to the control commands; the driver 15 controls the wireless device, which transmits/receives a wireless control command; block 16 administration by a management device, which analyzes and mutually converts the CEC message, and a wireless control command; table 17 ID HDMI devices, which correlates and stores the logical address and the physical address of the HDMI device; and table 18 ID group identification/ID of wireless devices, which correlates and stores the ID unique to the wireless device ID and group ID for identifying a group to which each of the wireless devices.

[0036] Device 1 type bridge supports both configurations with 4 and 10, described later; in the case of the example in figure 4, the relay of the wired transmission in the wireless transmission is performed in such a way that the AV content transmitted from a wired device, is transmitted to the wireless device; and in the case of the example in figure 10, the relay of the wireless transmission in a wired transmission is performed in such a way that the AV content transmitted from the wireless device that transmitted the wireless device.

[0037] Device 1 type bridge connects the HDMI device to the unit 11 a wired connection through a wired connection, connect a wireless device to the unit 13 of connectable wireless is through a wireless connection and mutually converts the control commands (the CEC message, and a wireless control command) between the HDMI device and the wireless device, to enable communication between them. HDMI cable, the connecting device 1 type bridge and the HDMI device, includes a line (line of digital signals) TMDS Differential Signal Transmission Minimized Differential Levels) for transmitting signals audio/video, which are digital signals in differential mode, and the CEC line, which is a bidirectional bus that transmits the control signal (message CEC) common to the devices. The HDMI cable can also include a line for the DDC (Display Data Channel)is used for transmitting EDID (Extended Data Identification Display), authentication information (HDCP Protection system of Digital Content with High-Bandwidth), etc.

[0038] the CEC Message is a signal control device based on the Protocol CEC HDMI. Between HDMI devices implementing various functional control actions through the exchange of signal control device between devices. In the case of CEC for each connected HDMI device receives a logical address (device type) and physical address (position of unit), resulting in a CEC message may be transmitted to a desired device by specifying the given logical address.

[0039] Next, here will be briefly described the logical address and the physical is the second address in the CEC.

In the HDMI-CEC many logical addresses may be processed depending on the type of device and may have a unique name in the network HDMI. These logical addresses are differentiated depending on the type of the HDMI device. For example, the logical address "0" denotes a display device such as TV; "4" indicates a playback device, such as a BD player; and "5" indicates an audio device, such as a speaker or AV amplifier.

[0040] Despite the fact that the physical address has a unique name in the network HDMI physical address (0.0.0.0) is normally assigned display device. If the network HDMI is added or disables the HDMI device, the physical address is automatically adjusted. Physical address: is the address for a variety of levels, including displaying device consists of a unique number n on the same levels and is presented in a format (n.n.n.n). If the HDMI device directly connected to the display device, is the first level, the HDMI device connected to the first device level, forms the second level, and the level number increases as the distance from the display device. The physical address is described in such a way that the level number increases with the leftmost n to the right in the above format.n.n.n).

[0052] figure 2 and 3, each device stores the ID information of the other connected devices (wired connection or a wireless connection) in the table, as in the case of device 1 type bridge. The ID information in the case of HDMI devices is stored in the table ID of HDMI devices, and wireless devices in the table group ID identification/ID of wireless devices. The ID information stored in these tables is generated through an automatic exchange of pre-defined commands, when appropriate connections are enabled through the inclusion, as in the case of device 1 type bridge. The contents of the tables, just the same as in tables connected devices.

[0053] the Present invention mainly differs in that it allows you to operate multiple devices-recipient together with each other for each group to maintain the minimum required amount of transmission of control commands when performing wireless AV transmission. For these purposes, the wireless transmission system includes a transmission device content that the air passes the AV content including video and/or audio, and multiple devices-recipients that receive wireless transmitted to the AV content, and at least one of the many device is the per-recipient consists of a wireless device of the recipient. For example, if multiple devices-recipients consists of a TV and a variety of speakers, the TV and the speakers can extract video and audio, respectively, of the AV content that is transmitted using a multicast transmission from a device to play the content, and as a consequence a variety of devices-recipients can be played simultaneously video and audio.

[0054] the transfer device and the content can take two basic forms, of which the first consists of a wired source device 2 and device 1 type bridge, and the second form consists only of a wireless source device 3. Describing first the form as a specific example, the device 1 type bridge (figure 1)of the transmission device content includes: table 18 ID group identification/ID of the wireless device corresponding to the table ID group identification, which stores the ID group identification to identify the group consisting of multiple devices-recipients; block 16 administration by a management device corresponding to the unit added ID group identification, which adds the ID group identification, extracted from table 18 ID group identification/ID of wireless devices in a control command to control the set device is in the recipient; and the block 13 wireless connection corresponds to block wireless transmission, wireless image transfers the control command added ID group identification. The same applies to the case of the second form of the device transfer content, consisting of a wireless source device 3 (figure 2(B)).

[0055] as a Result, the group is formed by arranging multiple devices-recipient (for example, television devices and one or more audio devices)connected via wireless AV transmission. If device-recipients must work with each other in relation to this group, then the air is passed to the management team with the added ID group identification. The wireless device receiver configured to receive control commands, if the management team is the group, and perform the operation in accordance with the control command. As a result, when the wireless AV transmission, multiple devices recipient can work together in relation to each group to maintain the minimum required amount of transmission of control commands and prevent temporary deviations receipt of the control commands to the devices will receive the Lee.

[0056] alternatively, any one of the wireless devices of the recipients belonging to the group can be defined as an authorized wireless device of the recipient. Authorized wireless device receiver may be a wireless way to communicate as an authorized group to which it belongs is authorized wireless device to the secondary transmission device content (device type 1 bridge or wireless device-source 3) or an authorized wireless device receiver of the other group. The consequence of the provision of this authorized device is the provision of opportunities for joint operation of the devices in the group and, for example, combining responses for the source.

[0057] the Command control mode, the wireless transmission includes, for example: command specific to the device, issued by a certain device; broadcasting a command issued to all groups without specifying a device of the recipient; and command, addressed the group issued a group. When receiving a command requiring a response (for example, the query command), the device returns a response (answer) to the transmission source of the command.

[0058] the Command control (CEC message, in the case of HDMI) mode wired transmission includes the impact for example: command specific to the device, issued by a certain device; and broadcasting a command issued to all connected devices without specifying a device of the recipient. Similarly, when receiving a command requiring a response (such as the query command), the device returns a response to the transmission source of the command.

[0059] (the First variant implementation)

In this embodiment, as described above, the transfer device and the content consists of the source device 2 HDMI and 1 type bridge, and all of the many devices-recipients consist of wireless devices-recipients (television devices and one or more audio devices). In this case, the device 1 type bridge wireless way connected to all wireless devices-recipients.

[0060] Figure 4 is a characteristic diagram of the configuration of a wireless transmission system in accordance with the first embodiment of the present invention. In this example, the source device 2 HDMI and 1 type bridge are connected via HDMI, and the device 1 type bridge wireless way connected to multiple wireless devices-recipients. Figure 4 TVs designated as 5a and 5b, and automodule designated as 6a-6c. TVs 5a, 5b and automodule with 6a through 6c are wireless devices receiving the TV 5a and 5b have the configuration of the device, shown in figure 3(B). Automodule with 6a through 6c are, for example, audio output devices such as speakers and amplifiers, AV, and consist of: unit wireless connection; a control unit; the driver controls the wireless device; block administration management device; table ID group identification/ID of wireless devices; and block audio output.

[0061] In the case of this example, the source device 2 HDMI includes table 7a ID HDMI devices; televisions 5a, 5b and automodule with 6a through 6C include table 7b ID group identification/ID of the wireless device; and the device 1 type bridge includes a table 7a ID HDMI devices and table 7b ID group identification/ID of wireless devices. The method of formation of these tables 7a and 7b will be described later with reference to Fig.6. TV 5a and automodule 6a and 6b are categorized to group A, and TV 5b and the audio module 6c are categorized to group B.

[0062] In the case of the first variant TVs 5a, 5b and automodule with 6a through 6c, which are wireless devices, recipients receive a control command transmitted over the air from the device transfer content (device type 1 bridge), if the management team added their own ID group identification. This allows wireless devices is m-recipients operate in conjunction with wireless devices-recipients belonging to the same group based on the accepted operation command.

[0063] Automodule c 6a through 6c are wireless devices, recipients include table 7b ID group identification/ID of wireless devices, depicted in figure 4, and therefore can accept a control command transmitted over the air from other wireless devices-recipients (TV 5a and 5b)belonging to the same group, if the command is added to the management group ID identification. In this case, the wireless device recipient may operate in conjunction with other wireless devices-recipients belonging to the same group based on the accepted commands, as described above.

For example, in the case of a wireless LAN information of the identifier is tion varies in accordance with the purpose of management (such as data transfer, administration, booking bands and confirmation). Information 82 group identification is information that specifies the host group ID group identification). The wireless device receiver receives the following packet fields 8, if this information is identical to its own group. If the control command is transmitted to a particular device, you must specify the ID of the device with respect to the device destination and as a consequence a separate field to indicate the given device ID. Alternatively, the device ID can also be used as a field information 82 group identification reception.

[0066] the Address 83 source transfer specifies the address of the wireless source device, which is the source of transmission, etc. Information 84 sequence number is used to determine duplication, in the case when the link includes the processing of re-transmission or is used by the receiver (device-recipient) for detecting that the number is omitted in the case where the communication does not include the processing of retransmission. In this frame format may include information 84 sequence number.

[0067] the Wireless command 85 control provides various control data to control devices-what uchitelya.

[0068] Fig.6 is a diagram of an example sequence of actions in the moment of inclusion in the system of wireless transmission in accordance with the first embodiment of the present invention. This is an example of a sequence of actions corresponds to the configuration of the system figure 4 and is described by a characteristic illustration of the device 1 type bridge, formiruyuschih depicted in the above figure 4 table 7a ID HDMI devices and table 7b ID group identification/ID of wireless devices. Figure 6 single line indicates a wireless control command; a double line indicates the CEC message; the dotted line indicates the command that is different from the management device; a circle indicates the source of the transmission of the command; and the arrow indicates the destination of the command. It is assumed that the source device 2 HDMI, the device 1 type bridge, TV 5a, the audio module 6a, the audio module 6b, TV 5b and the audio module 6c with figure 4 accordingly correspond to the HDMI source device, device type bridge, the TV 1, the audio module 1, the audio module 2, TV 2 and is dimodolo 3 to 6.

[0069] figure 6 it is assumed that the logical address of the HDMI CEC" corresponds to the logical address is depicted in figure 4 table 7a ID HDMI devices, and the control address of the wireless device corresponds to the ID group identification (Gr) and device ID (Dev) is depicted in figure 4 table 7b ID group identification/ID of wireless devices.

[0070] First, when the source device HDMI device type bridge included (S1), the device type bridge transmits the physical address (0.0.0.0) TV as the device information of the HDMI source device so that the virtual role of the TV 1 via HDMI connection (S2). As a result, the physical address of the device type bridge is defined as (0.0.0.0), and the physical address of the source device HDMI is defined as (1.0.0.0). The source device HDMI transmits the logical address "4" playback device through the CEC message <Message Polling>to announce that the source device HDMI is a playback device (S3). If it does not call Ack (acknowledgement), the address is accepted without changes. For device type bridge, the default group ID the ID of the device are set to "0", respectively.

[0071] When the TV 1 (S4), the television 1 detects the presence of the source device HDMI through the device, t is a bridge (S5) and transmits the device information of the TV 1 device type bridge (S6). The TV 1 transmits the device type bridge wireless control command, which requests the assignment of addresses (S7), and the device type bridge performs broadcast transmission of a wireless control command for announcement address (S8). As a result, the TV 1 receives the ID group ID "1" and the device ID "1" as the address.

[0072] the TV 1 transmits a request to return from standby (request) audio devices forming a group (S9). In this case, it is assumed that the TV 1 previously stores the MAC address (Access Control for Transmission Medium) automodule 1 and 2 and recognizes that these audio devices belong to the same group. Automodule 1 and 2 are included in accordance with the request for refund from the TV 1 (S10), and then transmit the corresponding parts of the device information device type bridge (S11).

[0073] the audio module 1 transmits the device type bridge wireless control command, which requests the assignment of addresses (S12), and the device type bridge performs broadcast transmission of a wireless control command for declaring addresses (S13). As a result, the audio module 1 receives as address ID group identification "0" and the device ID "2". This ID group ID "0" is the default value. Similarly, the audio module 2 transmits the mouth is oistu type bridge wireless control command, which requests the assignment of addresses (S14), and the device type bridge performs broadcast transmission of a wireless control command for announcement address (S15). As a result, the audio module 2 receives as address ID group identification "0 (default)" and the device ID "3".

[0074] as audio devices are present on the wireless side, the device type bridge transmits the logical address "5" of the audio device to the HDMI source device via the CEC message <Message Polling> (S16). If it does not cause the Ack, the address is accepted without changes.

[0075] the TV 1 transmits the audio module 1 wireless control command, which requests the ID group identification 1 (S17), and the audio module 1 sets the ID group identification in the "1" in accordance with this request, and then performs broadcast transmission of the ads installation group ID (S18). Similarly, the TV 1 transmits the audio module 2 wireless control command, which requests the ID group identification 1 (S19), and the audio module 2 sets the ID group identification in the "1" in accordance with this request, and then performs broadcast transmission of the ads installation group ID (S20).

[0076] in Other words, when TV 1 is activated, the device type bridge assigns a group ID identifying TV is ru 1 (S8), and the television 1 groups automodule 1 and 2 on the basis of the information identification device (such as a MAC address)unique to the audio module 1 and 2, and assigns a group ID identifying the grouped automodular 1 and 2 (S17, S19). This process leads to the formation of table 7b ID group identification/ID of wireless devices. The table is formed in exactly the same process for the other group.

[0077] Thus, tables 7a and 7b, depicted in figure 4, are formed by the sequence of actions described with reference to Fig.6.

[0078] Fig.7 is a diagram for explaining the correlated values of the tables shown in figure 4, and 6 stages. In table 7a, depicted in Fig.7(A), the physical address and the logical address device type bridge and the source device HDMI determined in the step (1) 6. This step (1) is a step of incorporating an HDMI device to configure the network HDMI and corresponds to the action S1 through S3. Physical address and logical address device type bridge (for audio) are determined at step (5) 6. This step (5) is a step in the Declaration of the source device HDMI connection, audio, and corresponds to step S16.

[0079] In the case of table 7b, depicted in Fig.7(B), ID group identification and the device ID for the device type bridge is determined at the step (1) 6. ID group ID manually the requirements and the device ID of the TV 1 is determined at the step (2) 6. This step (2) is a step of enabling the TV 1, which is a wireless device to connect to the device type bridge, and corresponds to the action of S4 on S8. ID group ID of the device in relation to automodular 1 and 2 are determined in the steps (4) and (6) 6. This step (4) is a step of enabling automodule 1 and 2 to connect to the device type bridge corresponding to the steps S10 to S15. Step (6) is a stage installation ID group identification for automodule 1 and 2 and corresponds to the action with S17 through S20. ID group ID of the device in relation to the television 2 and the audio module 3 group B can be obtained in exactly the same way and therefore will not be described.

[0080] Fig is a diagram of an example implementation procedures communication in the wireless transmission system in accordance with the first embodiment of the present invention. Procedures the following description is performed in the wireless transmission system shown in the above figure 4, based on table 7a ID HDMI devices and table 7b ID group identification/ID of wireless devices. Procedure (11) is a procedure in the case of transmitting a wireless control command (no response needed) wireless device and represents an example when the television 1 performs an operation to change g is emkosti sound in relation to the audio module 2. The TV 1 transmits a wireless control command <User Pressed Control> (Volume) to control the sound volume by specifying as the destination device ID "3" (dev3 are added) (S21). The audio module 2 corresponding to the device ID "3", performs the volume control in accordance with this wireless control command. As in this case, the answer is not required, the audio module 2 returns no response.

[0081] the Procedure (12) is a procedure in the case of transmitting a wireless control command (requiring a response) wireless device and represents an example when the TV does to the audio module 2 status request. The TV 1 transmits a wireless control command <Issue State Audio> status request by specifying as the destination device ID "3" (dev3 are added) (S22). The audio module 2 corresponding to the device ID "3", returns a wireless control command <a Status Report on Audio> (muting On), pointing to their own status as answer by specifying as the destination device ID "1" (called dev1) in accordance with this wireless control command (S23). Since in this case the required response, the audio module 2 returns a response.

[0082] the Procedure (13) is a procedure in the case of PE is Adachi wireless control command (no response needed) wireless devices within the group and is an example when TV 1 executes the query standby mode to automodular 1 and 2, in the same group. The TV 1 transmits a wireless control command <Idle> to query standby mode by specifying as the destination ID, the group ID "1" (Gr1) (S24). Automodule 1 and 2, corresponding to the ID group identification "1", transition to the standby mode in accordance with this wireless control command. As in this case, the answer is not required, automodule 1 and 2 do not return a response.

[0083] the Procedure (14) is a procedure in the case of transmitting a wireless control command (requiring a response) wireless devices within the group and represents an example when the TV 1 executes a query on the status of the power automodular 1 and 2. The TV 1 transmits a wireless control command < Give the power State of Device> to query power state by specifying as the destination ID, the group ID "1" (Gr1) (S25). The audio module 2 corresponding ID group identification "1", returns a wireless control command < Report Power Status> (Included), pointing to their own nutritional status, as answer by specifying as the destination device ID "1" (called dev1) in accordance with this wireless command the Board (S26). Similarly, the audio module 1 corresponding to the ID group identification "1", returns a wireless control command < Report Power Status> (Off), pointing to their own nutritional status, as answer by specifying as the destination device ID "1" (called dev1) in accordance with this wireless control command (S27). As in this case, you want the answer, then automodule 1 and 2 return the response.

[0084] the Procedure (15) is a procedure in the case of transmitting a wireless control command (no response needed) wireless devices within the group and represents an example when the device type bridge executes the query standby mode to the TV 1 and automodular 1 and 2 in group A (group ID identification "1"). Device type bridge transmits a wireless control command <Idle> to query standby mode by specifying as the destination ID, the group ID "1" (Gr1) (S28). In this example, the wireless control command derived externally to the group, accepted only the TV 1, which is an authorized wireless device receiver. The TV 1 transmits a wireless control command <Idle>adopted from the device type bridge by specifying as the recipient of the ID group ID "1" (Gr1) (S29). TV 1 and automodule 1 and 2, corresponding to the ID group identification "1", transition to the standby mode in accordance with this wireless control command. As in this case, the answer is not required, then the TV 1 and automodule 1 and 2 belonging to the group A, do not return the response.

[0085] the Procedure (16) is a procedure in the case of transmitting a wireless control command (requiring a response) wireless devices within the group and represents an example when the device 1 type bridge executes the query on the status of the power supply to the TV 1 and automodular 1 and 2 in group A (group ID identification "1"). Device type bridge transmits a wireless control command < Give the power State of Device> to query power state by specifying as the destination ID, the group ID "1" (Gr1) (S30). In this example, the wireless control command derived externally to the group, accepted only the TV 1, which is an authorized wireless device receiver. The TV 1 transmits a wireless control command < Give the power State of Device>adopted from the device type bridge by specifying as the destination device ID "2" (Dev2) (S31). The audio module 1 corresponding to the device ID "2", returns a wireless command from the management "Report Power Status" (Off), pointing his own nutritional status, as answer by specifying as the destination device ID "1" (called dev1) in accordance with this wireless control command (S32).

[0086] Similarly, the TV 1 transmits a wireless control command < Give the power State of Device>adopted from the device type bridge by specifying as the destination device ID "3" (dev3 are added) (S33). The audio module 2 corresponding to the device ID "3", returns a wireless control command "Report Power Status" (Off), pointing to their own nutritional status, as answer by specifying as the destination device ID "1" (called dev1) in accordance with this wireless control command (S34). TV 1 corresponding to the given ID identification "1", brings together many of the responses received from automodule 1 and 2, in one response, based on pre-defined rules, and specifies the device ID "0" (Dev0) to return this answer (S35). Device type bridge corresponding to the device ID "0", accepts this response.

[0087] As described procedures using (15) and (16) Fig, any one of the wireless devices of the recipients belonging to each group can be defined as an authorized wireless device of the recipient. Authorized wireless mustache is a device to the secondary wireless image communicates, as an authorized group to which the authorized wireless device receiver belongs, with the transmission device content (device type bridge) or an authorized wireless device receiver of the other group. Authorized wireless device receiver may be a wireless way to communicate with other devices-recipients within the group. For example, as shown in the above figure 4, if the group consists entirely of wireless devices-recipients, authorized wireless devices, recipients are defined by the TV 1, 2. Alternatively, as shown in described later in figure 10, if the group includes the device type bridge and device type bridge is connected via HDMI to the TV device, the authorized wireless device the recipient is determined by the device type bridge.

[0088] In the procedure (16), if the device type bridge performs broadcast transmission of the control commands, the TV 1, acting as an authorized wireless device recipient accepts the management team brings a lot of responses from other devices-recipients (automodule 1, 2) in the group to which belongs the TV 1 in one response, based on pre-defined rules, and returns the t of the response to the device type bridge.

[0089] This method return the response can be divided into two main cases. In the first case, the device type bridge receives a response devices-recipients (automodule 1, 2 and 3) from the authorized wireless devices-recipients (TV 1 and 2) groups in response to a query command from the source device HDMI and returns the responses to the HDMI source device. In the second case, when receiving a request coming from the outside with respect to the group of authorized wireless device receiver (TV 1) transmits a command to request wireless devices-recipients (automodular 1 and 2) within the group, receives responses from the device recipient and returns the response to the party that issued the command (in accordance with the procedure 16). In the second case, as described later in the second embodiment, the authorized wireless device receiver may be a device type bridge, and in this case, the query command is transmitted to the wired device connected to the device type bridge within the group.

[0090] In this regard, it should be defined a rule for combining multiple responses into a single response in the device type bridge or authorized wireless device to the secondary (TV or device type bridge). When following the rule of the return response is defined as an example, even if the from a variety of devices-recipients accept different answers, may return one answer in a manner similar to how when one device connected to the secondary. Consequently, the device can be operated without recognition of multiple connections (multicast connection).

[0091] (Return Answer)

1. If the management team regarding status request on/Off (for example, querying the status of the power supply, the display state of the video or the state of audio playback), if you among the connected devices-recipients of one or more devices "Enabled", the answer comes back "On"; otherwise, it returns Off.

2. If the management team in respect of the request for a numeric value (for example, request volume) as the response returns the maximum value of the numeric values of connected devices-recipients.

[0092] Although in the above description of each wireless device receiver is additionally assigned to the ID attribute of group identification in addition to the device ID, the ID group identification stored in the table group ID identification/ID of wireless devices, can be defined as a device ID of the authorized wireless device of the recipient. Device-recipients in each group retain the device ID in the compared the authorized wireless device receiver of their own group. In this case the ID field group identification", depicted in the previously described figure 4, table 7b ID group identification/ID of wireless devices can be defined as "ID of the authorized device group". For example, as the device ID of the TV 1, which is an authorized device is "1" in table 7b, automodule 1 and 2 in the same group as retain this ID of the authorized device "1". As a result, the device-recipients there is no need to have a separate attribute that indicates the ID group identification.

[0093] the Device of the recipient (audio device), non-authorized groups, exchanges control command only with the authorized device group and consequently may not save the entire table 7b ID group identification/ID of wireless devices, and the same operation can be performed, even if the recipient maintains only its own device ID and group ID the ID of the device is an authorized device.

[0104] (the Second Variant Implementation)

Figure 10 is a characteristic diagram of the configuration of a wireless transmission system in accordance with the second embodiment of the present invention. Devices 1a and 1b type bridge have the configuration of the device depicted in figure 1, and the television 4a and 4b has the device configuration is shown in figure 3(A). Automodule 6d and 6e are, for example, audio output devices, such to the to the speakers and AV amplifiers and consist of: unit wireless connection; control unit; the driver controls the wireless device; block administration management device; table ID group identification/ID of wireless devices; and block audio output.

[0105] In this embodiment, as described above, the transfer device and the content consists of a wireless source device 3, and the group consists of A device type 1a bridge, which is a wireless device receiver, and audio module 6d 4a and TV, which are connected via HDMI to the device 1a type bridge. Group B consists of a device type 1b bridge, which is a wireless device receiver, TV 4b, which is connected via HDMI to the device type 1b bridge, and audio module 6e, which is a wireless device receiver. In this case, the wireless source device 3 is connected wireless to devices 1a, 1b and audio module 6e.

[0106] In this example, both groups A and B include wireless devices-recipients and wired devices-recipients. In group A, the device 1a type bridge, the audio module 6d 4a and TV are connected via HDMI; device type 1a bridge is a wireless device receiver; and the audio module 6d 4a and TV are wired devices-recipients. Similarly in group B TV 4 is connected via HDMI to the device 1b type bridge; device type 1b bridge and the audio module 6e are wireless devices-recipients; and the television 4b is a wired device of the recipient. The audio module 6d in group A is set as the device is a repeater, which has the functions as the source device and the device of the recipient in the HDMI standard.

[0107] the Wireless source device 3 includes a table 7c ID group identification/ID of wireless devices; device type 1a bridge includes a table 7c ID group identification/ID of wireless devices and the table 7e ID HDMI devices; device type 1b bridge includes a table 7c ID group identification/ID of wireless devices and table 7d ID devices HDMI; audio module 6e includes a table 7c ID group identification/ID of wireless devices; TV 4a and the audio module 6d include table 7e ID HDMI devices; and TV 4b includes in the table 7d ID HDMI devices. The method of formation of these tables 7c through 7e will be described later with reference to 11.

[0108] In the case of the second form of the device 1a, 1b type bridge and the audio module 6e, which are wireless devices, recipients receive a control command transmitted over the air from the device transfer content (wireless source device 3)if the command is added to the management ID ID manually the requirements of their own group. If the wired device recipient, such as the TV and the audio module are connected via HDMI to the device type bridge, the device type bridge transmits the wireless devices receiving the control command as a CEC message. In the device-recipients belonging to the same group can work together on the basis of the control commands, adopted wireless devices, receivers 1a, 1b and audio module 6e.

[0109] the audio module 6e is a wireless device receiver and includes a table 7c ID group identification/ID of wireless devices, depicted in figure 10, and as a result, if transmitted in a wireless manner, the control command from the another wireless device of the recipient (device type 1b bridge)belonging to the same group, added his own ID group identification, the audio module 6e can take the management team. As the device type 1b bridge transmits a command to control the TV 4b as the CEC message, the device-recipients belonging to the same group can work together, even if the system is mixed wired transmission and wireless transmission.

[0110] 11 is a diagram of an example sequence of actions in the moment of inclusion in the system of wireless transmission in the accordance with the second embodiment of the present invention. This is an example of a sequence of actions corresponds to the configuration of the system figure 10 and will be described by a characteristic illustration of the device 1 type bridge forming table 7d, 7e ID HDMI devices and table 7c ID group identification/ID of wireless devices, depicted in figure 10. It is assumed that the wireless source device 3, the device 1a type bridge, the audio module 6d, TV 4a, the device type 1b bridge, 4b TV and the audio module 6e with figure 10 accordingly correspond to the wireless source device, the device 1 type bridge, the audio module 1, TV 1, device 2 type bridge, the TV 2 and the audio module 2 with 11.

[0111] First, when the device 1 type bridge, the audio module 1 and the TV 1 includes (S71), the TV 1 transmits the physical address (0.0.0.0) as the device information device type 1 bridge via an HDMI connection (S72).

The audio module 1 transmits the physical address (1.0.0.0) as the device information device type 1 bridge via an HDMI connection (S73). In the physical device address 1 type bridge is defined as (1.1.0.0); the physical address of the TV 1 is defined as (0.0.0.0); and the physical address of the audio module 1 is defined as (1.0.0.0). The audio module 1 transmits the logical address "5" audio device through the CEC message <Message Polling>, so to declare, is the audio device 1 is audio device (set S74). If it does not cause the Ack, the address is accepted without changes.

[0112] When the wireless source device (S75), the default ID of group identification and the device ID of the wireless device are set to "0", respectively. Device type 1 bridge detects the presence of the wireless source device (set s76), and transmits the device information with respect to the device 1 type bridge wireless source device (S77). Device type 1 bridge transmits the wireless source device of a wireless control command, which requests the assignment of addresses (S78) and the wireless source device performs broadcast transmission of a wireless control command for declaring addresses (S79). As a result, the device 1 type bridge receives the ID group ID "1" and the device ID "1" as the address.

[0113] Device 1 type bridge transmits the logical address "4" of the playback device via the CEC message <Message Polling> the audio module 1 and the TV 1, which is connected via HDMI to announce that the wireless source device (playback device) is connected wireless (S80). If it does not cause the Ack, the address is accepted without changes.

[0114] When the device switches on type 2 bridge and TV 2 (S81), TV 2 before the t information device device type 2 bridge (S82). In the physical address of the TV 2 is defined as (0.0.0.0), and the physical address of the device 2 type bridge is defined as (1.0.0.0). Upon detection of the presence of the wireless source device (S83) device type 2 bridge transmits its own device information, wireless source device (S84) and passes the request to the destination address of the wireless source device (S85). The wireless source device performs broadcast transmission of the device address 2 type bridge in response to the request destination address (S86). As a result, the device 2 type bridge receives the ID group ID "2" and the device ID "2" as the address.

[0115] Device 2 type bridge transmits the logical address "4" playback device through the CEC message <Message Polling> connected via HDMI to the TV 2 to declare that the wireless source device (playback device) is connected wireless (S87). If it does not cause the Ack, the address is accepted without changes.

[0116] Device 2 type bridge passes the request to return from standby (request) audio devices constituting a group (S88). In this case, it is assumed that the device 2 type bridge pre-stores the MAC address (Access Control for Transmission Medium) audio module 2 and recognizes that the data is s audio device belongs to the same group.

SUBSTANCE: initialisation and control of access for communication units includes assignment of identifiers to sets of units, at the same time identifiers may be used to control access to limited units of access, which provide certain services only to determined specified sets of units. In certain aspects initialisation of the unit may contain provision of a unique identifier for sets from one or more units, such as limited points of access and terminals of access, which are authorised to receive a service from limited points of access. Access control may be provided by means of an operation of a limited point of access and/or a network unit. In certain aspects initialisation of a unit contains provision of a list of preferable roaming for a unit. In certain aspects the unit may be initialised with the help of a list of preferable roaming using a beacon radio signal of self-initialisation.

EFFECT: optimised process of access control.
