Recently, HDMI (MUCH, multimedia interface high-definition) is widespread as a data interface, with which transmit digital video and digital audio that accompanies the video signal, high speed, for example, from a DVD recorder (DVD, digital versatile disc), digital set-top box, or other AV source (source AVI (audio - video) data) in a television receiver, a projector or other display. For example, patent document 1 includes a detailed description of the standard is that MUCH.

In addition, recently started to use SES (UBA, management of consumer electronic devices), which allows you to control an electronic device connected to a television receiver using the remote control of a television receiver. In this scheme, the signal MUCH add a line control signal UBA.

On Fig illustrates an example of the structure known AV system 200. AVI (audio video) system 200 includes device 210 written to disk, used as a source device, the device 370 playback of photos, used as a source device, and television receiver 250 that is used as a device of the consumer.

Device 370 playback photos and television receiver 250 are connected to each other via a cable 391 MUCH. Thus, one of the two ends of the cable 391 MUCH connected to the connector 371 MUCH device 370 playback of photos, and the other end connected to the connector 251 MUCH television receiver 250.

The device 210 written to disk and the television receiver 250 are connected to each other through the cable 392 MUCH. Thus, one of the two ends of the cable 392 MUCH connected to the connector 211 MEPC device 210 written to disk, and the other end connected to the connector 254 MUCH television receiver 250.

Television is the first receiver 250 is a device, appropriate UBU, and includes a module 276 receiving the infrared radiation (IR) receiver module that receives an infrared remote control signal from the sensor 277 remote control. In addition, the device 210 written to disk and device 370 replay photos is a device corresponding to the UBA.

In the AV system 200 shown in Fig, as the device 210 written to disk, and the device 370 playback photos are devices corresponding to the UBA. Therefore, the operations of the device 210 written to disk and device 370 playback pictures can be managed using the transmitter 277 remote control of the television receiver 250.

On Fig shows an example sequence of operations at the time when the device 370 playback photos and the device 210 writing to disk is connected to the television receiver 250.

In the AV system 200A instead of device 210 written to disk in the AV system 200 shown in Fig connected device 210A written to disk via cable 392 MUCH to a television receiver 250.

The device 210A writing to disk is a device that does not comply with the UBA. Therefore, when the device 210A written to disk connected to a television receiver 250 via the cable 392 MUCH, us is the device 210A written to disk receives the physical address [2000] from the television receiver 250, using the control Protocol MUCH, but does not receive the logical address of UBA.

Because the device 370 replay photos is a device corresponding to the UBA, AV system 200A operations device 370 playback pictures can be managed using the transmitter 277 remote control of the television receiver 250. However, since the device 210A writing to disk is a device that does not comply with the UBA operations device 210A recording on the disk cannot be controlled using the transmitter 277 remote control of the television receiver 250.

Therefore, the operation of the device 210A written to disk in AVI system 200A performs, using a transmitter 232 remote control device 210A written to disk, using the module 231 receiving the infrared radiation included in the device 210A written to disk.

The reserved line 501 and a line 502 STAGE, included in the cable MUCH, form a differential twisted pair. End 511 on the side of the source of the reserved line 501 is connected with 14 output connector MUCH source device. End 521 on the consumer side the reserved line 501 is connected with 14 output connector MEPC device of the consumer. In addition, the end of the 512 on the side of the source line 502 STAGE 19 is connected to the output connector MUCH source device. End 522 is and the consumer side of the line 502 STAGE 19 is connected to the output connector MEPC device of the consumer.

In the source device described above, the node Q1 between the resistor 421 setting the operating point and the dividing capacitor 413 AC 14 is connected to the output connector MUCH, and the above-described node Q2 between the resistor 431 leakage and dividing capacitor 414 AC 19 is connected to the output connector MUCH. In contrast, in the consumer device described above, the node Q3 between the resistor 451 leakage and dividing capacitor 433 AC 14 is connected to the output connector MUCH, and the above-described node Q4 between the choke coil 461 and the dividing capacitor 444 AC 19 is connected to the output connector MUCH.

Next will be described the operation when transferring data over a LAN, using the interfaces line of high-speed data transfer, built as described above.

In the device of the source transmitted signal (transmitted data) SG411 is passed to the side of the input circuit 411 of the LAN signal transmission and a differential signal (positive output and a negative output signal)corresponding to the signal SG411 transfer, is removed from circuit 411 of the LAN signal transmission. The differential signal output from the circuit 411 of the LAN signal transmission, transmit to the nodes P1 and P2, and is passed to the consumer device via a pair of lines (the reserved line 501 and a line 502 DSP) cable MUCH.

In addition, in condition the device user transmitted signal (transmitted data) SG417 is passed to the inlet side of the circuit 441 signal transmission LAN and the differential signal (positive output and a negative output signal)corresponding to the signal SG417 transfer, is removed from the circuit 441 signal transmission LAN. The differential signal output from the circuit 441 signal LAN is passed to the nodes P3 and P4 and transmit to the source device through a pair of lines (the reserved line 501 and a line 502 SS) cable MUCH.

In addition, the source device, since the side of the input circuit 415 of the signal LAN is connected to the nodes P1 and P2, the added signal from the transmission signal corresponding to the differential signal (current signal)output from the circuit 411 of the LAN signal transmission, and the signal corresponding to the differential signal transmitted from the device user, as described above, receive an output signal SG412 circuit 415 receiving a LAN signal. In the schema 416 subtracting the transmitted signal SG411 is subtracted from the output signal SG412 circuit 415 receiving a LAN signal. Therefore, the output signal SG413 circuit 416 subtraction corresponds to the transmitted signal (transmitted data) SG417 device of the consumer.

In addition, the consumer device, since the input side of the circuit 445 receiving a LAN signal is connected to the nodes P3 and P4, the added signal of the transmitted signal corresponding to the differential signal (current signal)output from the circuit 441 transmission signal is Ala LAN the received signal corresponding to the differential signal transmitted from the source device, as described above, get as the output signal SG418 of the circuit 445 receiving a LAN signal. In the circuit 446 subtracting the transmitted signal SG417 is subtracted from the output signal SG418 of the circuit 445 receiving a LAN signal. Therefore, the output signal SG419 circuit 416 subtraction corresponds to the transmitted signal (transmitted data) SG411 source device.

As described above, bi-directional data transfer over LAN may be provided between the interface line of high-speed data transmission source device and the interface line of high-speed data transmission device of the consumer.

It should be noted that figure 9, in addition to the above-described data transmission via LAN, line 502 DSP transmits, using the offset level of the DC voltage in the source device, the fact that the cable MUCH connected to the consumer device. Thus, the resistors 462 and 463 and the choke coil 461 in the consumer device make shift through 19 output cable MUCH, line 502 STAGE at around 4, when the cable MUCH connected to the consumer device. The source device selects a constant offset line 502 STAGE, using the filter of low frequencies, which includes the resistor 432 and the capacitor 433, and compares the constant shift which begins with a reference voltage Vref2 (for example, 1.4 In), using the comparator 434.

When the cable MUCH not connected to the consumer device, the voltage on 19 output connector MUCH source device is lower than the reference voltage Vref2, as is the resistor 431 leakage. In contrast, when the cable MUCH connected to the consumer device, the voltage on 19 output connector MUCH source device is higher than the reference voltage Vref2. Therefore, the output signal SG415 of the comparator 434 is at a high level, when the cable MUCH connected to the consumer device; in contrast, the output signal SG415 of the comparator 434 is at a low level. In line with this, the control module (CPU) of the source device can recognize, connected or no cable MUCH to the consumer device, on the basis of the output signal SG415 comparator 434.

In addition, figure 9 is enabled mutual recognition, the bias potential of the DC voltage of the reserved line 501 represents whether a device is connected to two ends of the cable MUCH, a device that can perform data transfer over LAN (below called "device corresponding e-MUCH") or a device that cannot perform data transfer over LAN (below referred to as " device not corresponding e-MUCH").

As described above, the source device raises the voltage (+5 V) the reserved line 501, using the resistor 421, and the device, the user lowers the voltage of the reserved line 501 by using the resistor 451. The resistors 421 and 451 are not present in devices that do not meet e-MUCH.

The source device compares, as described above, the DC potential of the reserved line 501, which was passed through the filter of low frequencies, which includes the resistor 422 and the capacitor 423, with the reference voltage Vref1, using the comparator 424. When the consumer device is a device corresponding to the e-MUCH, and includes a resistor 451 leakage, the voltage of the reserved line 501 becomes equal to 2.5 C. However, when the consumer device is a device that does not comply with e-MUCH, and does not include the resistor 451 leakage, the voltage of the reserved line 501 becomes 5 V, due to the presence of resistor 421 setting the operating point.

Therefore, if the reference voltage Vref1 is, for example, 3,75, the output signal SG414 of the comparator 424 is set to low level, when the consumer device is a device corresponding to the e-MUCH, and otherwise set to a high level. In line with this, the control module (CPU) of the source device can recognize whether a or a consumer device the device that meet the General e-MUCH, on the basis of the output signal SG414 of the comparator 424.

Similarly, the consumer device compares, as described above, the potential of the DC voltage of the reserved line 501, which has passed through the filter of low frequencies, which includes the resistor 452 and the capacitor 453, with the reference voltage Vref3, using the comparator 454. When the source device is a device corresponding to the e-MUCH, and includes a resistor 421 setting the operating point, the voltage of the reserved line 501 becomes equal to 2.5 C. However, when the source device is a device that does not comply with e-MUCH, and does not include the resistor 421 setting the operating point, the voltage of the reserved line 501 becomes 0 due to the presence of resistor 451 leakage.

Therefore, if the reference voltage Vref3 is, for example, 1.25V, the output signal SG416 of the comparator 454 has a high level when the source device is a device corresponding to the e-MUCH, and otherwise is low. In line with this, the control module (CPU) of the device user can recognize whether or not a device is a source device, the corresponding e-MUCH, on the basis of the output signal SG416 of the comparator 454.

In accordance with the design example shown n the figure 9, in the interface, which performs using one cable MUCH, sending video and audio data, exchange and authentication information of connected devices, the data transfer control device and data transfer on the LAN, perform data transmission via LAN, using bi-directional data transfer through a pair of differential data paths, and the connection state of the interface is reported, using the potential of the direct voltage bias at least one of the data paths. Thus, it becomes possible spatial separation, in which the line PTC or line PDA physically not used for data transmission LAN. As a result, the scheme for data transmission via LAN can be formed independently from the electrical specifications defined for BWW, and stable and reliable data transfer over the LAN can be implemented at low cost.

It should be noted that the resistor 421 setting the operating point shown in figure 9, may be provided in the cable MUCH, instead of the source device. In this case, the terminals of the resistor 421 setting the operating point, respectively, are connected, in addition to the lines envisaged in the cable MUCH to the reserved line 501 and a line (signal line)connected to the power supply potential of the power source).

In addition, the resistor 451 mouth is ovci operating point and the resistor 463, shown in figure 9, may be provided in the cable MUCH instead of a device of the consumer. In this case, the terminals of the resistor 451 setting the operating point, respectively, is connected, along the lines envisaged in the cable MUCH to the reserved line 501 and a line (line to ground)connected to ground (reference potential). In addition, the findings of the resistor 463, respectively, are connected, along the lines envisaged in the cable MUCH, line 502 chipboard and line (line to ground)connected to ground (reference potential).

(e) When the device V written to disk connected to a television receiver 250 via the cable 392 MUCH, (f) the device V written to disk receives the physical address [2000] from the television receiver 250, using the control Protocol MUCH. Here, because the device W writing to disk is a device that does not comply with the UBA, the device V written to disk does not perform the operation of determining the logical address of UBA.

(g) thereafter, the user sets the device V play photos the fact that the physical address [2000] is a device (recording device), which manages the device V playback of photos, instead of the physical address [2000]. Floor the user can perform such an installation using, for example, the module A operations of the user connected to the CPU 374. (h) In accordance with the above described setting, the device V play photos specifies the logical address {1}, as the burner is controlled UBU, based on the table on Fig. In this case, after the device V play photos recognizes that there is no other device that has a logical address {1}, fulfilling the message of the survey, using the control Protocol UBU, the device V play photos specifies the logical address (1), as the logical address.

(i) After the device V play photos specifies the logical address {1}, the corresponding physical address [2000]as described above, the device V play photos notifies the television receiver 250 to the fact that the physical address [2000] is a device {1}, corresponding to the UBA doing a report on the physical address using the Protocol control UBA.

Figure 11 illustrates an example sequence of operations during playback control device V play photos and device U disk writes performed by using the transmitter 277 remote control of the television receiver 250.

(a) When the user switches the input to eliminate the STV V play photos, using a transmitter 277 remote control of the television receiver 250, (b) the television receiver 250 notifies the connected device (s)corresponding to the UBA, the fact that the input has been switched from the television receiver 250, the device V play photos, executing SeStreamPath [0000]→[1000], using the Protocol of management of UBA.

(c) the Device V play photos with the logical address [1000] detects this notification and notifies the connected device (s)corresponding to the UBA, the fact that the device is running UBU switched on the device U play photos in the command ActiveSource {4}→{F}. (d) In accordance with this, the television receiver 250 switches the destination of transmission of the remote control device V play photos.

(e) When the user clicks the play button transmitter 277 remote control of the television receiver 250, (f) the television receiver 250 notifies the connected device (s)corresponding to the UBA, that came UserControlPressed:PB {4}, using the Protocol of management of UBA. (g) the Device V play photos with the logical address {4} detects this notification, displays an image that contained the memory type flash and transmits the output of the playback of the television receiver 250 via cable 391 MUCH. Accordingly, the displayed image storage devices like flash display in a television receiver 250.

Then, (h), when the user switches the input to the device V written to disk, using a transmitter 277 remote control of the television receiver 250, (i) the television receiver 250 notifies the connected device (s)corresponding to the UBA, the fact that the input has been switched from the device V play photos on the device V written to disk by executing the command SeStreamPath [1000]→[2000], using the Protocol of management of UBA.

(j) Because the management of UBA physical address [2000] perform by using the device V playback of photos, instead of a device V written to disk, the device V play photos detects this notification. The device V play photos notifies the connected device (s)corresponding to the UBA, the fact that the management of UBA virtual switched on the device V written to disk, by performing ActiveSource {1}→{F}. (k) In accordance with this, the television receiver 250 switches the destination of transmission of the remote control device V written to disk.

(m) When the user who presses the play button on the transmitter 277 remote control of the television receiver 250, (n) the television receiver 250 (CPU 271) notifies the connected device (s)corresponding to the UBA, that came UserControlPressed:PB {1}, using the Protocol of management of UBA. Here, the CPU 271 is a module generating a control signal (p) As the logical address {1} performed by using the device V playback of photos, instead of a device V written to disk, the device V play photos detects this notification. The device V play photos converts the team play UBU in the infra-red remote command control and transmits an infrared command remote control using infrared radiation, resulting notifies the device V recording on a disc that does not comply with the UBA. This conversion is performed, for example, by using the CPU 374. In this sense, the CPU 374 module is to transform the control signal.

(q) the Device V written to disk detects this notification, reproduces the image recorded on the disc, and transmits the output of the playback of the television receiver 250 via the cable 392 MUCH. Accordingly, reproduced from a disk image display in a television receiver 250.

On Fig is illustrated using a dashed line, the control channel is reproduced is eating above described device V written to disk, using the transmitter 277 remote control of the television receiver 250. On Fig illustrated using dotted lines, the control channel playback device V play photos. Team play UBU (UserControlPressed:PB {1})transmitted from the television receiver 250, passed from module 372 transfer MUCH through the CPU 374 in the RAM 376 and temporarily kept in RAM 376.

The CPU 374 reads and analyzes the management team UBU contained in the RAM 376. The CPU 374 controls the circuit 383 infrared transmission for converting commands to play UBU team infrared remote control and transmits this command to the infrared remote control infrared signal from the module 384 infrared transmission.

As described above, in the AV system 100 shown in figure 1, when the user performs operations on the device V written to disk, which is a device that does not comply with the UBA, using a transmitter 277 remote control of the television receiver 250, the management team UBU, addressed to the device V written to disk, generated from the television receiver 250. In the device V play photos management team UBU transform command to the infrared remote control and the infrared command remotely what about the control is passed to the device V written to disk. Therefore, in the AV system 100 shown in figure 1, the device V written to disk, which is a device that does not comply with the UBA connected to the television receiver 250 can be managed by using a transmitter 277 remote control of the television receiver 250.

It should be noted that, in the embodiment shown in figure 1, presents the device V play photos, which converts the control command UBU, addressed to the device V written to disk, the command infrared remote control and transmits a command to the infrared remote control device V written to disk. However, the device V play photos may convert the control command UBU in the control signal in a predetermined format, and may transmit the control signal to the device V written to the disk through the channel of bi-directional transmission of data, consisting of the reserved line and the line EXTRA cables 391 and 392 MUCH, as shown in Fig. In this case, the circuit 383 infrared transmission and module 384 infrared transmission become unnecessary in the device V play photos. Also, in this case, the module 231 receiving the infrared radiation becomes unnecessary in the device V written to disk.

Next will be described another option you have is filling up the present invention. On Fig shows an example of the structure of the AV system 100', used as another embodiment of the present invention. On Fig plots corresponding to figure 1, are denoted by the same numbers of reference positions, and their detailed description is not provided here.

The device V' play photos and television receiver 250' are connected to each other via a cable 391 MUCH. Thus, one of the two ends of the cable 391 MUCH connected to the connector 371 MUCH device V' play photos, and the other end of the cable 391 MUCH connected to the connector 251 MUCH television receiver 250'. In addition, the device V written to disk and the television receiver 250' are connected to each other through the cable 392 MUCH. Thus, one of the two ends of the cable 392 MUCH connected to the connector 211 MEPC device V written to disk, and the other end of the cable 392 MUCH connected to the connector 254 MUCH television receiver 250'.

The television receiver 250' is a device corresponding to the UBA. In addition to the module (IR receiving module) 276 receiving the infrared radiation receiving infrared remote control transmitter 277 remote control, the television receiver 250' includes infrared module 278 transmission, which transmits an infrared signal. The television receiver 250' is from the battle of the device, obtained by adding an infrared transmission schemes (not shown) and an infrared module 278 transmission to a television receiver 250 in the AV system 100 in figure 1. Here, under the control of the CPU 271 (see figure 4), an infrared transmission scheme manages infrared module 278 transmission and generates an infrared signal.

In addition, the device V' replay photos is a device corresponding to the UBA. The device V' replay photos is a device obtained by removing the infrared circuit 383 transmission and an infrared module 384 transfer device V play photos in the system 100 AB of figure 1. In addition, the device W writing to disk is a device that does not comply with the UBA, and includes a module 231 receiving the infrared radiation, which receives the infrared signal. The device V recording on the hard disk, which is the same as the device V written to disk in the AV system 100 in figure 1.

In the AV system 100'shown in Fig when the device V' play photos connected with the television receiver 250, the device V' play photos obtains the physical address [1000] of the television receiver 250'using the control Protocol MUCH. Because the device V' play photos itself, not only is em a playback device, the device V' play photos specifies the logical address {4}, as the playback device, managed UBU on the basis of the table shown in Fig.

Furthermore, in the AV system 100'shown in Fig when the device V written to disk connected to the TV receiver 250', the device V written to disk receives the physical address [2000] from the television receiver 250'using the control Protocol MUCH. Here, because the device W writing to disk is a device that does not comply with the UBA, the device V written to disk does not perform the operation of determining the logical address of UBA.

After that, the user sets in a television receiver 250' the fact that the physical address [2000] is a device (recording device), which controls the television receiver 250', instead of the physical address [2000]. In accordance with the above-described installation, the television receiver 250' specifies the logical address {1} as a recording device controlled UBU, on the basis of the table shown in Fig.

On Fig presents examples displayed during setup the user remote control of the television receiver 250'. The television receiver 250' includes a connector 251 MUCH related to input 1 MUCH, and a connector 254 MUCH related to input 2 MUCH. Figure 1 (a) depicts the case in which when the cursor position SA is input 1 MUCH. Displayed the fact that the device (device B play photos)connected to input 1 MUCH control command to control the UBA,.

On Fig (b) illustrates the case in which the position of the cursor CA is installed on the input 2 MUCH. This displays the fact that the device (device B written to disk)connected to the input 2 MUCH control using infrared commands. Here, the user may determine that the device (V written to disk)connected to the input 2 MUCH, is a recording device. This operation is, as described above, the operation of the installation in a television receiver 250', consisting in the fact that the physical address [2000] is a device (recording device), which the television receiver 250' controls instead of the physical address [2000].

In the AV system 100'shown in Fig when the user clicks on the play button after switching the input to the device V' play photos, using a transmitter 277 remote control of the television receiver 250', command control playback of the UBA, addressed to the device V' play photos, generate from the television receiver 250', and transmit the device 70 V' play photos. Accordingly, the playback operation begins in the device V' play photos, and reproducible image data is passed through the cable MUCH 391 in the television receiver 250'. Accordingly, the displayed image device V' playback pictures display in a television receiver 250'.

Furthermore, in the AV system 100'shown in Fig when the user clicks on the play button after switching the input to the device V written to disk, using a transmitter 277 remote control of the television receiver 250', generate the command control playback of the UBA, addressed to the device V written to disk, from the television receiver 250'. In a television receiver 250' management team play UBU is converted into an infrared command, and an infrared command is passed from the infrared module 278 transmission device V written to disk.

SUBSTANCE: system for scheduling data selection for transmission in a data network includes a plurality of daughter elements as well as a credit allocator and a transmission selector. The transmission selector is communicatively connected to the credit allocator, wherein each credit can be used to transmit data. The credit allocator operates to provide credits to one of allowable daughter elements and daughter elements having a negative credit counter. The credit allocator also operates to maintain a credit balance which represents the available total volume of unallocated credits, and subtracts the provided credits from the credit balance. The transmission selector operates to select one allowable and operable daughter element for extraction from a queue and add credits to the credit balance in accordance with the amount of data selected for extraction from the queue.

EFFECT: improved queuing using weight coefficients based on reverse management of credits which can be used in case of traffic with controlled exchange rate.
