The technical field
The invention relates to a method of sending commands to the managed device to the system for remote control of the controlled device to the control device, suited for the transmission of commands to the managed device a managed device for receiving commands from the control device, to a computer software product, the method of presenting advertisements to the user, as well as to the signal.
From U.S. patent 4807031 known method, in which commands are transmitted on the main channel with the use of video in an interactive device using the selected modulation sequence of fields of the video signal, acting on the subconscious of the user. The received modulated field of the video image in the viewable area of the TV, where each field is alternating, proportionally increased and decreased the brightness of the horizontal scan lines are constantly monitored using a light sensitive device positioned close to the TV user. The device selects the control data of the television program and generates an IR (infrared) modulated signal with control data. IR modulated signal is radiated into an interactive device that decodare the control data and selectively performs a predefined action in response to the decoded control data.
The disadvantage of this method is that despite the fact that the modulation in the fields of video invisible to the user, the photosensitive device must be positioned so that it could detect the modulated field. This usually means that the input device such as a sensor must be positioned over the desired place (places) of the screen that obscures this place for the user. In addition, you need a separate device, which converts the modulated field in the command signal, which is sent using infrared radiation into an interactive device. This makes the method expensive and difficult to install. An additional disadvantage is that the method is applicable only with video.
A brief statement of the substance of the invention
The present invention is to develop a method of transmitting commands, which provides direct sending commands to the managed device.
The problem is solved in accordance with the invention by developing a method of transmitting commands to perform the following operations:
forming a watermark that contains the command that should be executed by the managed device,
forming a signal with a watermark that contains the watermark and the information block is to send in a managed device
the transmission signal with a watermark in the managed device to the managed device has completed the command. In accordance with the invention, a command is transmitted to the managed device by embedding it in a transmitted signal with a watermark. Thus, the information block is used as a carrier for the team, and there is no need for a control signal, which transmits the command to the controlled device. A managed device can read the signal with the watermark using a microphone or similar device, and decode and execute built-in commands. The method is applicable in any situation and in any environment, for example, in a public place, where the loudspeaker generates audio signals, or the exhibition, where the object is displayed on the screen using a signal that contains the command. The information block may be transmitted by transmitting it by radio or pre-storing media - tape or CD, and then play, and the managed device can receive the signal with a watermark. In practice, the effect of the use of the method lies in the fact that the reproduction signal with the watermark will execute the managed device to take some action, because the transmission of the command is invisible, thanks to the use the of the watermark. Since the audio signals are well distributed, they are very suitable as the modulated signal for the teams. Using this method, you can remotely manage the device using the control device.
Know the use of watermarks for embedding additional information in the information block. This additional information may be, for example, uniform resource locators (Varos) for a resource for the world wide web that contains more information related to the information block (see, for example, U.S. patent 5841978). After receiving an information block with additional embedded information for the managed device can decode Varos and retrieve the associated resource to display it to the user. However, this approach is limited by embedding specific kinds of additional information for presentation to the user and cannot be extended.
In the present invention using watermarks to insert commands in the information block, which is used for remote control of the controlled device.
In the described embodiment, a signal with a watermark generated in the first area by using a watermark in the first area to merge the watermark signal with the information signal, to provide the Commissioner information block in the first area. Preferably the first region is either acoustic area or the visual area. The information block is usually in the second region, for example in an electric field. The advantage is that the original input signal marked with a watermark, and there are no signals that are not marked watermark. For example, the exhibition of paintings watermark to generate the picture and instead of displaying copies of the picture with a watermark visual watermark is projected on to the real picture hanging on the wall. All pictures, etc. made with the picture, will have an embedded watermark. In addition, when the transmission signal with a watermark in an acoustic or a visual field is not required to create a physical channel, such as a cable, to the team reached the managed device. This method is suitable for remote control of any type of devices. For example, the managed device may be implemented as a mobile phone, which the owner just have to focus on the source signal, to receive a signal. Because the command is embedded in the audio or video signal, which is transmitted using a device such as a TV or a speaker, the signal containing a command that directly reaches the managed device.
In an additional embodiment, device is and the team selected at least one from a group consisting of: managing the physical movement of parts of the managed device, the audio signal output by the managed device, playback of the visual signal output by the managed device and adjusting the magnitude of at least one parameter associated with the command. The Central computer, using this method, to give voice commands to other devices you want to manage. Thus, the user can directly hear what serves the team, and see how responsive device, which is preferable when sending invisible commands and the sudden discovery that the devices operate differently. However, rather than an actual voice commands interpreted by a device, this team is built into the signal, which contains the actual command. Thus, speech commands are freely programmable, for example, for local languages or user preferences without requiring any reprogramming of the device. One user may prefer a polite and formal commands, while another may desire a clear and concise commands. Both users are using the method in accordance with the invention, can program their own team, however they want if this were neither required to modify the multitude of the creation of the actual commands, no reprogramming of the device to recognize user commands. Commands can be embedded in the form of short identifiers, such as numbers, which are defined in the same way in the Central computer and the device.
An additional object of the invention is the creation of a system for implementing a method of transmitting commands to the managed device.
This problem is solved in accordance with the invention by creating a system that contains a means of embedding for forming a watermark that contains the command that should be executed by the managed device, the tool stamp watermark, designed for generation of a signal with a watermark that contains the watermark and the information block that is passed to the managed device, the output means to transmit a signal with a watermark in the controlled device to execute the command receiving means for receiving signal in a managed device, decoding means for receiving information from the signal and receiving commands from the information block and actuating the tool to execute the command.
Another objective of the invention is to provide a control device, which would directly send commands to the managed device.
Task d is moved in accordance with the invention by generating a control device, containing means embedding for forming a watermark that contains the command that should be executed by the managed device, the tool stamp watermark intended to signal that contains the watermark and the information block transmitted to the managed device, the output means to transmit a signal with a watermark in the controlled device to execute the command.
Another object of the invention is the creation of a managed device, intended for direct reception team in the first field of the control device.
The problem is solved in accordance with the invention, by creating a managed device containing a receiving means for receiving signal in a managed device, decoding means for receiving information from the signal and receiving commands from the information block and actuating the tool to execute the command.
The invention is also a computer program product for performing a method of transmitting commands.
Another additional object of the invention is to provide a method for presenting advertising, which provides for the direct transmission of the commands associated with the advertisement, to the managed device.
Put the does is solved by creating a way contains the following operations: forming a watermark that contains the command that should be executed by the managed device, and the command refers to the presentation of advertising, the formation of a signal with a watermark that contains the watermark and the information block that is passed to the managed device, and the transmission signal with a watermark in the controlled device to execute the command by generating advertising and presentation of advertising to the user. In this way the advertising message can directly reach consumers. Managed devices can be generally implemented in the form of a Teddy bear or other toy and, if the advertising out of this toy, the owner will most likely have to react to it positively.
The method further comprises the steps of maintaining a user profile through the sale of the controlled device to the user, determining, using the user profile of the product that the user will likely need to buy and add to the command ID of the item. The advantage of this implementation is that the user profile can be used to target advertising goods that advertising was more adapted to the user. This type of personalized message will greatly stimulate p is odagiu advertised goods, as it seems that it arises from a managed device and aimed directly at her owner, and not from some non-personal public announcement.

Description of the preferred embodiment variants of the invention
Some of the means indicated on the drawings, implemented in software.
In the first variant embodiment of the system 100 (figure 1) contains the control device 110 and the managed device 130. The controller 110 includes a module 111 determination module 112 of the load module 113 embedding module 114 mark watermark and output module 115. Control device in accordance with the invention is intended to transmit one or more commands to the managed device 130, which is tenderly to run these commands. Module 111 determines these commands. Commands are preferably associated with the information unit 116, which must be transmitted to the managed device 130. Information unit 116 is, for example, television program, radio, film, advertising, image or sound or any part thereof.
Commands preferably are connected with parts of the information unit 116. For example, to represent a specific part of the background information regarding the object should preferably be given when the object is reproduced during playback. The managed device 130 will then represent the background information at the appropriate time. As another example, the command "play recording of the song" should preferably be given when this song is sung in the information unit 116, so that the actuator 130 "sings along" with the information unit 116. However, teams should not be associated with all of the information unit 116. This is true, when the communication unit 116 must be transmitted with the transmission on the radio, where it can take on other devices. This is discussed in more detail below.
The command can contain values of one or more parameters that affect the execution of the command. For example, the team may only apply to one specific managed device is Wu, but it can take other managed devices. In this case, the command must contain a parameter that identifies one specific controlled device. The managed device 130 may adjust the value of at least one parameter in this configuration, based on the value specified in the command. For example, the command may relate to the volume and contain the numerical value of the volume. The managed device 130 should then adjust its volume to the value specified in the command.
Module 112 load loads the information unit 116. Information unit 116 can be a single signal or the broadcast multiple signals, or it can be a data item stored in the device 117 memory. This memory may be a tape or disc, such as DVD or video compact disc. It can also be taken from an external source, such as Internet, satellite or local network. Information unit 116 may be selected by a user using a remote control or other input device, but the choice may also be made by the managing device 110.
Module 113 embedding generates a watermark containing the command to be executed by the managed device 130. The watermark must be p is the step in the managed device 130 together with the information unit 116 so to watermark formed on the basis of the information unit 116 or its presentation. Sometimes embedding commands must be synchronized with the process in the information unit 116, so that their execution was synchronized with this process. In other situations, you need to run commands at specific points in time, for example, when the commands are used to enable or disable the managed device 130 in accordance with a predetermined plan. In these situations, the expected time playback information block 116 must be known so that the team could be built into the appropriate places in the view. Embedding commands can be executed using any kind of stamp watermark or otherwise disguise the information appropriate for the information unit 116. The watermark can be embedded in the representation of the information unit 116, which is located in the second area, such as an electric field. The view command built into it, then sent to the module 114 mark watermark, which generates a signal 120 with a watermark, which can be transferred to the first region, such as acoustic or visual area in the managed device 130. Alternative command can be embedded by forming the information signal, representing the information unit 116 and a signal with a watermark containing the command and output both signals in the first area, where they can be combined to form a signal 120 with a watermark. This may require two modules 114 mark watermark and/or the two output module 115, one for each signal, the control unit 110. The team is then embedded in the signal 120 with the watermark in the first area, thanks to the merger.
In any case, the module 114 mark watermark 120 generates a signal with a watermark that contains a watermark and information unit 116. The output module 115 then transmits the signal 120 with a watermark in the managed device 130 to execute the command. Although in the present description, the operations are performed in real time, actually not necessary for the control device 110 to build the command signal and the output signal 120 with a watermark immediately. The controller 110 can store a signal 120 with a watermark on the memory device, such as device 117 memory, for later output. For example, the controller 110 may create a marked watermarked video tapes, these tapes can be sold in stores and played the owner of the controlled device 130. Thus, the transmission performed by the output module 115 may the be implemented using output media moreover, the signal 120 with the watermark can be read for transmission in the first area in the managed device 130.
The managed device 130 includes a receiving module 131, the module 132 decoding and Executive module 133. The receiving module 131 receives the signal 120 in the first region and submit it to the module 132 decoding. The receiving module 131 may be a microphone, a camera, or with a light sensor.
Module 132 receives an information decoding unit 116 from the signal 120. Usually the reception and decoding provides conversion signal 120 to the view in the electric field. Module 132 of the decoder then processes the information unit 116 to receive the command.
The team then submitted to the Executive module 133, which executes the command. The team may refer to managing the physical movement of parts of the managed device 130, the audio signal output by the managed device 130, the reproduction of a visual output signal controlled device 130, the adjustment value for at least one parameter associated with the command, or other actions that should perform controlled device 130. Some examples of possible commands is given below with reference to figure 2.
Commands can be embedded as short identifiers, such as numbers, which determine the s same way in the Central computer and the device. It makes the information that you want to embed, very short, but it allows you to embed a potentially long and complex commands. You only need to control unit 130 viewed the appropriate command for the ID which is embedded in the signal 120. One team may start a sequence of predefined actions. For example, one team "to begin dancing" may start the movement of the feet, head and arms of the doll, which is arranged accordingly.
The controller 110 may be implemented as a computer program product 140, adapted for the processor to perform the control in accordance with the invention. The computer program product 140 enables a programmable device when executing a computer program product to function as the control device 110.
Similarly, the managed device 130 can be implemented as a computer program product 141 enabling a programmable device when executing a computer program product to operate as a managed device 130.
Figure 2 shows schematically a second variant implementation of the system 100. In this case, the control device 110 is designed for the output signal 120 by passing him on the radio. For example, the audio signal 120 m which can be displayed using the loudspeaker so, all managed devices can read it using a microphone. A managed device can be implemented as a multimedia station, such as a television receiver 230 or personal stereostructure 231. It can also be implemented as a toy such as a Teddy bear 232. Other variants of implementation. Managed devices 230, 231, 232 have respective receiving devices 131, in the case of an audio signal, preferably a microphone, which can read the signal 120 to the radio.
It may happen that a particular command is intended only for a specific managed device. Other managed devices should not run this command, as this may lead to undesirable consequences. To ensure that only the specified managed device performs the command, control device 110 should add the ID for a specific managed device to the command before embedding it in the information unit 116. For example, the information unit 116 may be a background music into the speaker, and it can be intended only for a single managed device 130, which is within the scope of the loudspeaker. Note that in this case, although the information unit 116 before the is through the transmission of radio controlled device 130, it is not associated with the information unit 116.
The command executed in the managed device may refer to managing the physical movement of parts of the managed device. For example, the controller 110 can send a Teddy bear 232 command to move her paw 239. If the commands embedded in the information unit 116, are coordinated with the process in the information block 116, then the physical movements performed by the managed device, will be seen as reacting to the information unit 116. It refers to the movement of one or more parts of the controlled device, and audible or visual output signal using the controlled equipment or other actions it may take in response to receiving commands.
As an example, the actuating means 133 in the plush bear 232 may be adapted to move the paw 239 or other parts of the body bears 232, as well as to play a song or display a sentence or a word in response to receiving the appropriate command from the control device 110. If the information unit 116 is a television program, then the teams can be built in places where the appropriate action to happen in the television program. The effect will be that Teddy bear 232 will sing together singing Persian the characters of the television program, to move parts of the body, when the characters of television programs do so For an observer it will seem like a Teddy bear 232 was actually responding to a television program.
It is possible to implement control device 110 and the managed device 130 in a single physical device, such as a Teddy bear 232. Mishka 232 will contain the output module 115, the receiving module 131, and the module 111 determination module 112 of the load module 113 embedding module 114 mark watermarks, module 132 decoding and Executive module 133. Two Teddy bears, so implemented, can now exchanging commands and respond to commands from each other. For an observer it will seem as if they really interact with each other. For example, one Teddy bear can start singing the song, implemented with the beginning of playing pre-recorded music unit, and the other will sing together as the musical output unit has a built-in command, which causes another Teddy bear to start singing. Preferably, the command includes a parameter that indicates at what point in the music block another Teddy bear should start playing to both sang synchronously.
Figure 3 shows another variant implementation of the control device is TBA 110 and the controlled device 130. The managed device 130 can be implemented as a mobile phone 310, a laptop computer 311 or personal digital assistant 312, or any other type of mobile device. The control device 110 in this case is designed to transmit the information unit 116 in the managed device 320, 311, 312 with the team to record or register of statistical data or built-in information associated with the information unit 116. The advantage of the controlled device 130 as a mobile phone 310, a laptop computer 311 or personal digital assistant 312 is that they usually already have a receiving module 131, such as a microphone, and require no external modifications. If the module 132 decoding and Executive module 133 can be implemented as software modules, does not require adjustment of technical support, thus saving costs in the production of these managed devices 130. To implement commands to be executed by the Executive module 133, the owner of the controlled device 130 need only be targeted device 130 to the source signal 120, such as a loudspeaker. Of course, the microphone must be sensitive enough to read the signal 120 without direction to the source.
Managed devices 310, 311, 312 in this var the ante embodiment of the invention adapted for in order to receive a signal containing information unit 116, to get the built in command and execute the command. Commands related to register the received information blocks. For example, the command may be the expression "to write in the registration file with the value of the parameter that identifies the accepted information unit. It can also order a managed device to present the questionnaire to the user, for example, to assess its preference for a received information block. User input is then registered together with the identification for the received information block. In addition, the team may order a managed device to depict the buy button, which the user can enable to directly buy a piece of information.
Managed devices 310, 311, 312 can be connected through the connection unit 320 to the network 330, such as Internet. The connecting device 320 may be a transmission device or a docking station for managed devices 310, 311, 312, or base station that can transmit radio communication session via the network 320. Connected to the network 330 are also many servers 340. Using the network connection, managed devices 310, 311, 312 can transmit the information recorded in their registers is the R files in the server 340. Using this information, the server 340 may generate or maintain a user profile for the owner of the managed devices 310, 311, 312. Many servers 340 may also contain service e-Commerce, which take the registration file, or other data from managed devices 310, 311, 312 and perform on the basis of their actions.
The system 100 and the various embodiments of the control device 110 and the controlled device 130, as described above, can be used to improve radio and television programmes, interactive films and advertising. The managed device 130 can be used to draw attention to a television unit, when it receives a specific command, for example, by playing back pre-recorded sound module, which contains audio messages. If the TV unit then shows the advertising transmission, which is built of a particular team, the managed device 130 will attract attention to this advertising gear. This increases the external impact of the commercials.
The same principle can be used in other situations. Two managed devices 130 can respond to each other if they are in a certain area, for example, by embedding commands unique is the principal identifier for ourselves in all audio output signals. This command should force other managed devices 130 to respond with a greeting or to initiate a joint action, such as singing a song. This command can also be embedded in background music in a toy store so that its owner could take his Teddy bear 232 to the store and get interaction with other selling Teddy bears 232.
4 shows an alternative embodiment of system 100. If a managed device, such as a Teddy bear 232, personalized and has an identifier that is associated with its owner 420, then this ID can be used for distributing targeted advertisements. Sold 400 may monitor data on sales of Teddy bears 232 using the base 410 of the data, and can match these data with other data marketing in order to get the profile 411 user for consumers who bought Teddy bear 232. On the basis of the profile 411 user sold 400 may generate targeted advertising.
Sold 400 then uses its control device 110 in order to embed the command associated with advertising in the information unit 116, which is the owner of a particular managed device 130 may need to take. The command must contain the parameter values that amlawdaily for targeted advertising, such as an identifier for a Teddy bear 232, ID, and the price for the advertised product or service. When the command is embedded in the information block 116, block 116 is sent to a Teddy bear 232 in the form of a signal 120. Teddy bear 232 receives the signal 120 using a microphone 131, and decode built in command. It then executes the command so that targeted advertising 430 submitted to the owner 420.
There are various ways to build and present targeted advertising 430. Several methods are described below.
Suppose that there is a new model or accessory. On the basis of the profile 410 user 420 owner sold 400 determines that the owner 420 want to buy this new model or accessory. Sold 400 selects "submit advertising and adjusts the corresponding values of parameters for advertising, such as the ID for the new item and its price, the identifier for the user and possibly other parameters.
Then sold 400 determines the information unit 116, which is the owner of 420 wants to take. This can be a television program showing a Teddy bear 232, CD or DVD with the music associated with the image display Teddy bears 232, etc. Alternative background music in a place where the shop is located could be ODA is defined as the information unit 116. Background music is presented to the customers through the loudspeaker. Sold 400 embeds a command to present advertising" with the appropriate values for the parameters in the background music.
When the target Teddy bear 232 receives the signal of the background music, it decodes the command and executes it through the formation and representation of a signal advertising 430 to its owner. It is preferable to audio messages advertising the goods specified in the command. Teddy bear 232 then executes the command by saying its owner, for example: "Hey, I have a new friend. It is available now only for dollars 29,95! Run to the store." This type of personalized message will greatly stimulate sales of the advertised product, as it seems that it arises from a Teddy bear 232 and aimed directly at his owner, and not from some non-personal announcement over the loudspeaker.
Alternatively, if the managed device 130 is a display advertising can be shown on the display. The managed device 130 can load a video or audio units and present them to the user. This mechanism can be used to load and present the advertisement in response to the command.
