Description

Signal stream transmission opening and closing method and device

Technical Field

The present invention relates to the field of display control technologies, and in particular, to a method and an apparatus for turning on and off signal stream transmission.

Background

In the prior art, a video wall display system may include a main control device, a front end, and a display end (as shown in fig. 1), where the main control device may include a main control device, a source end, and a destination end, where the source end may be any one of input chips included in an input module in fig. 1, and the destination end may be any one of output chips included in an output module in fig. 1, and the main control device is connected to the input module and the output module through a transmission bus. The front end is used to provide a signal stream, such as a Personal Computer (PC), a Camera (Camera), a projector, etc. in fig. 1, and the source end may be connected to the front end through a data line, and convert an analog signal sent by the front end into a digital signal and output the digital signal to a corresponding destination end. The destination terminal may receive the digital signal sent by the source terminal, convert the digital signal into a displayable signal, and send the displayable signal to the display terminal for displaying, where the display terminal may be one or more split screens included in the television wall shown in fig. 1, or may also be any display. Each output chip shown in fig. 1 may generally control a plurality of split screens included in the television wall, one or more of the split screens constituting a display window of the television wall. A tv wall may generally display a plurality of display windows, for example, 9 windows from window 1 to window 9 shown in fig. 1, but may also display other number of display windows. Each input chip may include a plurality of input channels, one input channel may be used to connect a front end and one input chip, each output chip may also include a plurality of output channels, and one output channel may be used to connect a display end and one output chip. The main control device is mainly used for controlling signal flow input to each chip.

At present, when the display control of the television wall is performed, a plurality of display schemes can be preset at a user control end, and the switching time is set, the user control end can send a switching command to a main control device at intervals of the switching time, and then the main control device can switch the current display scheme of the television wall to the display scheme specified by the switching command. For example, the first display scheme may specify a screen that divides the television wall into 1 × 2 screens, that is, two display windows, where the window 1 receives and displays a signal stream of a personal computer, and the window 2 receives and displays a signal stream of a camera, and then the switching command for switching to the first display scheme may include two switching messages, where the first switching message is switching information for controlling the window 1 to receive and display a signal stream of the personal computer, and the second switching message is switching information for controlling the window 2 to receive and display a signal stream of the camera.

However, currently, the main control device receives switching information according to a single switching information unit, and after receiving a piece of switching information, it waits for the completion of the execution of the piece of switching information, that is, after completing the reception and display of a signal stream of the personal computer by a display window corresponding to the piece of switching information, it will continue to receive the next piece of switching information. When the display screen of the television wall is small, the switching method can meet the time delay requirement, but when the display screen of the television wall is large and the display scheme with more display windows is switched, the switching time required by the whole television wall is large, for example, when the number of split screens is 80, when the display windows of the television wall are switched from 9 to 10, the time is usually consumed for 4-5 seconds, obviously, the time required for switching is too long, so that the user experience quality is poor.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

The technical background of the embodiments of the present invention is described below.

Currently, a main control device receives switching information according to a single switching information unit, and after receiving a piece of switching information, the main control device waits for the completion of the execution of the switching information, that is, after completing the reception of a signal stream of a personal computer by a display window corresponding to the switching information and displaying the signal stream, the main control device continues to receive the next piece of switching information. When the display screen of the television wall is small, the switching method can meet the time delay requirement, but when the display screen of the television wall is large and the display scheme with more display windows is switched, the switching time required by the whole television wall is large, for example, when the number of split screens is 80, when the display windows of the television wall are switched from 9 to 10, the time is usually consumed for 4-5 seconds, obviously, the time required for switching is too long, so that the user experience quality is poor.

In view of this, an embodiment of the present invention provides a method for starting signal stream transmission, in which when a main control device obtains M pieces of start information for starting M pieces of signal stream transmission, a first command is directly sent to a corresponding destination according to the M pieces of start information, so as to notify the destination to bind a receiving resource of the destination with a corresponding transmission channel, that is, to prepare for receiving a signal stream; on the other hand, the master control device sends the second command to the source end corresponding to the first start information, that is, the start information that the corresponding destination ends are bound successfully, so as to notify the source end to bind the sending resource of the source end with the corresponding transmission channel, after the source end is bound successfully, the transmission channel between the source end and the destination end is conducted, and the source end can send the signal stream to the destination end through the transmission channel that is directly bound. After the master control device obtains the plurality of pieces of opening information, the next piece of opening information is executed without waiting for the completion of the corresponding process of one piece of opening information, and the plurality of pieces of opening information are directly sent to the destination end, so that all the destination ends can perform binding operation at the same time, and the source end is similar to the destination end, thereby reducing the waiting time of the master control device, reducing the total time consumption for switching the display schemes, and improving the user experience quality.

The technical scheme provided by the embodiment of the invention is described below by combining the accompanying drawings.

Referring to fig. 2, an embodiment of the present invention provides a method for starting signal stream transmission, where the method can be executed by a master control device according to the embodiment of the present invention. The flow of the method is described below.

In the embodiment of the invention, a user can set a plurality of display schemes at the user control end, and the number of the display windows to be displayed by the television wall and the content to be displayed by each display window can be set at the user control end. After the user control end sets a plurality of display schemes, the time for the television wall to display one of the display schemes can be set, and a switching command is sent to the main control device at the set time, so that the main control device controls the television wall to be switched to the display scheme indicated by the switching command. Of course, when the tv wall does not display any content, the main control device may also receive a switching command from the user control end, so that the tv wall displays the display scheme indicated by the switching command, which is described below by taking the case that the tv wall does not currently display any content as an example.

S201: the master control device acquires M pieces of opening information for opening transmission of M pieces of signal streams.

In the embodiment of the invention, after the user control end sends the switching command to the main control device, the main control device receives the switching command. Specifically, the master control device may include a service management layer and a service implementation layer. The user control end can receive a switching command sent by the user control end through the service management layer, and after receiving the switching command, the service management layer can acquire M pieces of opening information for opening transmission of M signal streams according to a display scheme indicated by the switching command, wherein M is a positive integer. For example, the display scheme indicated by the switching command is that a television wall is required to display two display windows, window 1 displays a picture of a signal stream of a PC, and window 2 displays a picture of a signal stream of a camera, so the service management layer can acquire two pieces of opening information of the two signal streams, because the display of the display window of the television wall is controlled by an output chip connected to the television wall, that is, a destination, the opening information 1 may be a destination corresponding to the control window 1 to receive and control the signal stream of the display PC, and the opening information 2 may be a destination corresponding to the control window 2 to receive and control the signal stream of the display camera.

In the embodiment of the invention, after the service management layer acquires the M pieces of opening information, the M pieces of opening information are sent to the service implementation layer, and the service implementation layer stores the M pieces of opening information. Specifically, the service management layer may send M pieces of opening information to the service implementation layer in sequence, and use the two pieces of opening information as an example, the service management layer may send opening information 1 to the service implementation layer first, and then send opening information 2 to the service implementation layer, and the service implementation layer stores the opening information each time it receives one piece of opening information, and of course, the service management layer may also send the opening information 1 and the opening information 2 in other sequences, for example, send opening information 2 first and then send opening information 1, or the service management layer sends opening information 1 and opening information 2 to the service implementation layer at the same time.

S202: the main control device sends a starting command to the service realization layer through the service management layer.

In the embodiment of the present invention, after the service implementation layer receives and stores the M pieces of opening information, the service management layer may send a start command to the service implementation layer to notify the service implementation layer to start executing the opening information. Specifically, after receiving and storing the M pieces of opening information, the service implementation layer may send a confirmation message to the service management layer to notify the service management layer that the storage is completed, and after receiving the confirmation message, the service management layer sends a start command to the service implementation layer.

S203: the main control device sends a first command to the N destination terminals through the service implementation layer.

In the embodiment of the invention, the destination is an output chip which is connected with the split screens of the television wall and is used for controlling the split screen display, one destination can receive signals of the source and control the display of a plurality of split screens, for example, one destination can control the display of two split screens. One piece of opening information corresponds to one display window, and one display window is usually formed by a plurality of split screens, and one split screen has a destination corresponding to the split screen for controlling split screen display, that is, if the television wall includes N destination, where N is a positive integer, then one piece of opening information corresponds to at least one destination in the N destination. For example, the display window corresponding to the opening information 1 is composed of a split screen 1 to a split screen 4, the display window corresponding to the opening information 2 is composed of a split screen 5 to a split screen 8, the destination 1 can control the split screen 1 and the split screen 2, the destination 2 can control the split screen 3 and the split screen 4, the destination 3 can control the split screen 5 and the split screen 6, and the destination 4 can control the split screen 7 and the split screen 8, so that the opening information 1 corresponds to the destination 1 and the destination 2, and the opening information 2 corresponds to the destination 3 and the destination 4.

In the embodiment of the invention, the service implementation layer can send the first command to the N destination terminals according to the M pieces of opening information. The first command is used for instructing the N destination terminals to bind the receiving resources of the destination terminals with the transmission channels indicated by the opening information corresponding to the destination terminals.

Specifically, the service implementation layer may send the first command to the destination corresponding to each piece of the opening information according to each piece of the opening information. Referring to fig. 3, following the two examples of the opening information, fig. 3 is a schematic flow chart illustrating the service implementation layer sending the first command to the destination 1 to the destination 4.

S2031: the service implementation layer sends a first command to the destination 1.

Specifically, the service implementation layer may send the first command to the destination sequentially, for example, the first command may be sent to the destination corresponding to the opening information according to the order of the opening information, that is, the service implementation layer may send the first command to the destination corresponding to the opening information 1 sequentially, and then send the first command to the destination corresponding to the opening information 2 sequentially, of course, the service implementation layer may also send the first command according to other orders, for example, send the first command to the destination corresponding to the opening information 2 sequentially, and then send the first command to the destination corresponding to the opening information 1 sequentially. In fig. 3, the start-up information 1 is first sent as an example.

The first command is used to instruct the destination 1 to bind its own receiving resource with the transmission channel indicated by the opening information 1, specifically, one signal stream needs to be transmitted by one transmission channel, for example, the signal stream corresponding to the opening information 1 may be transmitted by the transmission channel 1, and the signal stream corresponding to the opening information 2 may be transmitted by the transmission channel 2. The transmission channel is a channel formed by an input channel and an output channel in the main control device, and one input channel and one output channel are matched with each other to form one transmission channel. Then, the first command received by the destination 1 is to bind the receiving resource of the destination 1 with the transmission channel 1.

S2032: the service implementation layer receives the response message sent by the destination terminal 1.

Specifically, after receiving and storing the first command sent by the service implementation layer, the destination 1 feeds back a response message to the service implementation layer to notify the service implementation layer that the first command has been received by itself.

S2033: the service implementation layer sends a first command to the destination 2.

Specifically, after receiving the response message of the destination terminal 1, the service implementation layer may send a first command to the destination terminal 2. Since the destination 2 and the destination 1 need to receive the same signal stream, that is, both the signal streams are signal streams of a PC, the signal streams are also transmitted through the same transmission channel, that is, the first command received by the destination 2 is to bind the receiving resource of the destination 2 with the transmission channel 1. It can be seen that, after knowing that the destination terminal 1 receives the first command, the main control device does not wait for the destination terminal 1 to complete the execution, but directly continues to send the first command to the destination terminal 2, so that different destination terminals can receive the first command in time, that is, different destination terminals can execute the first command in parallel, thereby reducing the waiting time of the main control device, and further reducing the total time consumption of the television wall for displaying a plurality of display windows.

S2034: the service implementation layer receives the response message sent by the destination terminal 2.

Specifically, after receiving and storing the first command sent by the service implementation layer, the destination 2 feeds back a response message to the service implementation layer to notify the service implementation layer that the first command has been received by itself.

S2035: the service implementation layer sends a first command to the destination 3.

Specifically, after receiving the response message of the destination 2, the service implementation layer may send a first command to the destination 3. The destination 3 corresponds to the opening information 2, the signal stream that needs to be received is the signal stream of the camera, the signal stream corresponding to the opening information 2 is transmitted by the transmission channel 2, and then the first command received by the destination 3 is to bind the receiving resource of the destination 3 with the transmission channel 2.

It should be noted that the first command of the embodiment of the present invention is to instruct the destination to bind its own receiving resource with the corresponding transmission channel, that is, the first command is only used to illustrate the binding effect, and the transmission channel bound with the destination indicated by the first command may be different, for example, the destination 2 receives the first command to bind the destination 2 with the transmission channel 1, and the destination 3 receives the first command to bind the destination 3 with the transmission channel 2, so that the content specifically carried by the first command received by different destinations may be different.

S2036: the service implementation layer receives the response message sent by the destination terminal 3.

Specifically, after receiving and storing the first command sent by the service implementation layer, the destination 3 feeds back a response message to the service implementation layer to notify the service implementation layer that the first command has been received by itself.

S2037: the service implementation layer sends a first command to the destination 4.

Specifically, after receiving the response message of the destination terminal 3, the service implementation layer may send a first command to the destination terminal 2. Since the destination 4 and the destination 3 need to receive the same signal stream, that is, both the signal streams are signal streams of a PC, the signal streams are also transmitted through the same transmission channel, that is, the first command received by the destination 4 is to bind the receiving resource of the destination 4 with the transmission channel 2.

S2038: the service implementation layer receives the response message sent by the destination terminal 4.

Specifically, after receiving and storing the first command sent by the service implementation layer, the destination 4 feeds back a response message to the service implementation layer to notify the service implementation layer that the first command has been received by itself.

In the embodiment of the invention, after receiving the first command, the destination 1 to the destination 4 can execute the first command, namely bind the self receiving resource with the transmission channel indicated by the self corresponding opening information, then store the binding result in the destination, and return the binding result to the service implementation layer when the service implementation layer requests to obtain the binding result. In addition, a synchronization module may be disposed in the destination, where the synchronization module has a function that the destination executes the first command after receiving the first command, and stores the first execution result in the synchronization module, and a service implementation layer of the main control device can directly access the synchronization module, that is, the service implementation layer can directly read the first execution result stored in the synchronization module.

Please continue with fig. 2.

S204: the main control device determines first opening information from the M pieces of opening information.

In the embodiment of the present invention, after the main control device sends the first command to the N destination terminals through the service implementation layer, it is further required to know a result of the N destination terminals executing the first command, that is, whether the N destination terminals are successfully bound, so that the main control device further reads the first execution result from the synchronization module of the destination terminal through the service implementation layer, and further determines the first opening information from the M pieces of opening information according to the first execution result. The first opening information refers to opening information that all destination terminals corresponding to the opening information are bound successfully.

Specifically, since the time required for binding the destination is longer than the time for sending the first command by the service implementation layer, the destination may not complete the binding process when the service implementation layer reads the first execution result, and therefore, the service display layer starts timing after all the first commands are sent, and reads the first execution results from the N destinations in sequence in a polling manner within the preset time. For example, the service implementation layer sequentially reads first execution results in the destination 1 to the destination 4, and if binding is still incomplete in the destination 1 to the destination 4, that is, there is a destination that has not read the first execution results, continues to sequentially read the first execution results in the destination 1 to the destination 4 until the timing time is reached; or whether the first execution result is read or not, or the content represented by the read first execution result, continuously and sequentially reading the first execution results from the destination 1 to the destination 4 until the timing time is reached.

After the timing time is reached, if there are destination terminals that have not read the first execution result or the first execution result represents that the binding fails, because the destination terminals may fail to bind with the transmission channel successfully and cannot accept the signal stream, the subsequent transmission cannot be executed continuously, so the service implementation layer removes the opening information corresponding to the destination terminals from the M pieces of opening information and takes the remaining opening information as the first opening information.

S205: and the main control device sends a second command to the P source ends according to the first opening information.

Since the subsequent transmission flows of other opening information except the first opening information cannot be continued, only the second command needs to be sent to the P source ends corresponding to the first opening information, where P is a positive integer. And the second command is used for indicating the P source ends to bind the sending resources of the P source ends with the transmission channels indicated by the opening information corresponding to the P source ends. Wherein one piece of start information corresponds to one source terminal.

Please refer to fig. 4, following the two examples of the start information, where P source ends are source ends connected to the PC and the camera, respectively, and fig. 3 is a schematic flow chart of a service implementation layer sending a second command to the source ends, where fig. 3 shows a case where all destination ends corresponding to the two start information are successfully bound. The source end connected to the PC may be, for example, the source end 1, and the source end connected to the camera may be, for example, the source end 2.

S2051: the service implementation layer sends a second command to the source end 1.

Specifically, the service implementation layer may send the second command to the source end in sequence, for example, the second command may be sent to the source end corresponding to the opening information according to the sequence of the opening information, that is, the service implementation layer may send the second command to the source end corresponding to the opening information 1 first and then send the second command to the source end corresponding to the opening information 2, and of course, the service implementation layer may also send the second command according to other sequences, for example, send the second command to the source end corresponding to the opening information 2 first and then send the second command to the source end corresponding to the opening information 1 in sequence. In fig. 3, the start-up information 1 is sent first, i.e. sent to the source end 1 first.

Specifically, one signal stream needs to be transmitted through one transmission channel, for example, the signal stream corresponding to the opening information 1 may be transmitted through the transmission channel 1, and the signal stream corresponding to the opening information 2 may be transmitted through the transmission channel 2. Then the second command received by the source 1 is to bind the transmission resource of the source to the transmission channel 1.

S2052: the service implementation layer receives the response message sent by the source end 1.

Specifically, after receiving and storing the second command sent by the service implementation layer, the source end 1 feeds back a response message to the service implementation layer to notify the service implementation layer that the second command has been received by itself.

S2053: the service implementation layer sends a second command to the source end 2.

Specifically, after receiving the response message of the source end 1, the service implementation layer may send a second command to the source end 2. Since the source end 2 corresponds to the start information 2, and the signal stream of the start information 2 is transmitted through the transmission channel 2, the second command received by the source end 2 is to bind the transmission resource of the source end with the transmission channel 2. It can be seen that, after knowing that the source end 1 receives the second command, the master control device does not wait for the source end 1 to execute the second command, but directly continues to send the second command to the source end 2, so that different source ends can receive the second command in time, that is, different source ends can execute the second command in parallel, thereby reducing the waiting time of the master control device, and further reducing the total time consumption of the video wall for displaying a plurality of display windows.

It should be noted that the second command in the embodiment of the present invention is to instruct the source end to bind its own transmission resource with a corresponding transmission channel, that is, the second command is only used for explaining the binding, and the transmission channels bound to the source end and indicated by the second command may be different, for example, the second command received by the source end 1 is to bind the transmission resource of the source end with the transmission channel 1, and the second command received by the source end 2 is to bind the transmission resource of the source end with the transmission channel 2, so that the contents specifically carried by the second commands received by different source ends may be different.

S2054: the service implementation layer receives the response message sent by the source end 2.

Specifically, after receiving and storing the second command sent by the service implementation layer, the source end 2 feeds back a response message to the service implementation layer to notify the service implementation layer that the second command has been received by itself.

In the embodiment of the present invention, after receiving the second command, the source end 1 and the source end 2 may execute the second command, that is, bind the sending resource thereof with the transmission channel indicated by the opening information corresponding to the source end, store the binding result in the destination end, and send the binding result to the service implementation layer when the service implementation layer requests to obtain the binding result. In addition, the source end may also be provided with a synchronization module, where the synchronization module has a function that the destination end executes the second command after receiving the second command, and stores the second execution result in the synchronization module, and the service implementation layer of the main control device can directly access the synchronization module, that is, the service implementation layer can directly read the second execution result stored in the synchronization module.

In the embodiment of the invention, after the P source ends are successfully bound with the corresponding transmission channels, namely the transmission link between the source end and the destination end is successfully established, the signal stream can be directly transmitted to the destination end through the bound transmission channels, and after the destination end receives the signal stream, the split-screen display of the television wall can be controlled according to the signal stream. Since the destination control display belongs to the category of the prior art, it is not described herein in detail.

Please continue with fig. 2.

S206: the main control device determines second opening information from the M pieces of opening information.

In the embodiment of the present invention, after the main control device sends the second command to the P source ends through the service implementation layer, it is further required to know a result of the P source ends executing the second command, that is, whether the P source ends are successfully bound, so that the main control device may further read the second execution result from the synchronization module of the source ends through the service implementation layer, and further determine the second opening information from the M pieces of opening information according to the second execution result. The second start information is start information that source end binding corresponding to the start information is unsuccessful.

Specifically, since the time required for the source end to bind is longer than the time for the service implementation layer to send the second command, the source end may not complete the binding process when the service implementation layer reads the second execution result, and therefore, the service display layer starts to time after all the second commands are sent, and reads the second execution results from P source ends in sequence in a polling manner within the preset time. For example, the service implementation layer sequentially reads the second execution results in the source end 1 and the source end 2, and if the source end still has incomplete binding, that is, there is a source end that has not read the second execution result, continues to sequentially read the second execution result in the source end until the timing time is reached; or, whether the second execution result is read or not, or the content represented by the read second execution result, the second execution results of the source end 1 and the source end 2 are continuously and sequentially read until the timing time is reached.

S207: the main control device feeds back the execution result of the starting command to the service management layer through the service implementation layer.

After the timing time is reached, if there is a destination end which does not read the first execution result or the first execution result represents the binding failure, because the destination end may fail to bind with the transmission channel successfully and cannot send the signal stream, the subsequent transmission cannot be continuously executed, so the service implementation layer can also feed back the information as the execution result of the start command to the service management layer, that is, the start information of the successful start and the start information of the failed start are sent to the service management layer, so that the service management layer can inform the user control end in time, so that the user finds the failure and arranges maintenance.

In the embodiment of the present invention, when the content of multiple display windows is being displayed on the television wall, if a display scheme needs to be switched, the currently displayed window needs to be closed, so please refer to fig. 5, the embodiment of the present invention further provides a signal stream transmission closing method, which can also be executed by the main control device, and a flow of the method is described as follows.

S501: the master control device acquires L pieces of information to be closed for closing transmission of L pieces of signal streams.

In the embodiment of the present invention, if the content of the video wall is already displayed, that is, when the signal stream is being transmitted between the destination and the source, if the main control device receives the switch command again, the main control device may first close the signal stream being transmitted before executing the opening information included in the switch command.

Specifically, after receiving the switching command through the service management layer, the main control device finds the opening information of L signal flows to be closed in the opening information stored in the main control device, and marks the opening information as information to be closed, where L is a positive integer. The opening information of the signal flow that needs to be closed may be, for example, opening information that the signal flow is successfully opened in the opening procedure, or may be all opening information included in the last switching command stored in the master control device.

In the embodiment of the invention, after the service management layer acquires the L pieces of information to be closed, the L pieces of information to be closed are sent to the service implementation layer, and the service implementation layer stores the L pieces of information to be closed. Specifically, the process of sending the information to be closed to the service implementation layer by the service management layer is similar to the process of sending the information to be closed to the service implementation layer, so the process may refer to the description of the opening information, and is not described herein again.

S502: the main control device sends a starting command to the service realization layer through the service management layer.

In the embodiment of the present invention, after the service implementation layer receives and stores L pieces of information to be closed, the service management layer may send a start command to the service implementation layer to notify the service implementation layer to start executing the information to be closed. Specifically, after receiving and storing the L pieces of information to be closed, the service implementation layer may send a confirmation message to the service management layer to notify the service management layer that the storage of the service management layer is completed, and after receiving the confirmation message, the service management layer sends a start command to the service implementation layer to start the closing of the signal stream transmission.

S503: and the master control device sends a third command to the L source ends through the service implementation layer.

In the embodiment of the present invention, when the signal stream transmission is turned off, if the reception of the destination signal stream is turned off first, the source terminal may further continue to transmit the signal stream, so that it is likely that the signal stream accesses an inaccessible area of the destination, which causes a device failure, and therefore, the transmission of the source signal stream needs to be turned off first. Referring to fig. 6, by using the above two examples of the opening information, after the transmission of the signal streams corresponding to the two opening information is successfully opened, the transmission of the two signal streams also needs to be closed when the transmission of the signal streams is closed, that is, the number of the information to be closed is 2, where the information to be closed 1 corresponds to the source end 1, and the information to be closed 2 corresponds to the source end 2.

S5031: the service implementation layer sends a third command to the source end 1.

Specifically, the service implementation layer may send the third command to the source end in sequence, for example, the third command may be sent to the corresponding source end according to the sequence of the information to be closed, that is, the service implementation layer may send the second command to the source end corresponding to the information to be closed 1 first, and then send the second command to the source end corresponding to the information to be closed 2, and of course, the service implementation layer may also send according to other sequences, for example, send to the source end corresponding to the information to be closed 2 first, and then send to the source end corresponding to the information to be closed 1. In fig. 6, the information to be turned off 1 is sent first, that is, sent to the source end 1 first.

The third command is used to instruct the source end to unbundle its own transmission resource and the bound transmission channel to stop transmission of the signal stream, and the transmission channel after being unbundled may also be used for transmission of signal streams of other source ends. For example, the third command received by the source 1 is to unbundle the transmission resource of the source 1 from the transmission channel 1.

S5032: the service implementation layer receives the response message sent by the source end 1.

Specifically, after receiving and storing the third command sent by the service implementation layer, the source end 1 feeds back a response message to the service implementation layer to notify the service implementation layer that the third command has been received by itself.

S5033: the service implementation layer sends a third command to the source end 2.

Specifically, after receiving the response message of the source end 1, the service implementation layer may send a third command to the source end 2. The third command received by the source peer 2 is to unbundle the transmission resource of the source peer 2 from the transmission channel 2. It can be seen that, after knowing that the source end 1 receives the third command, the master control device does not wait for the source end to complete the execution, but directly continues to send the third command to the source end 2, so that different source ends can receive the third command in time, that is, different source ends can execute the third command in parallel, thereby reducing the waiting time of the master control device, and further reducing the total time consumed for switching the display scheme.

S5034: the service implementation layer receives the response message sent by the source end 2.

Specifically, after receiving and storing the third command sent by the service implementation layer, the source end 2 feeds back a response message to the service implementation layer to notify the service implementation layer that the third command has been received by itself.

In the embodiment of the invention, after receiving the third command, the source end connecting the PC and the camera can execute the third command, that is, unbind the sending resource of the source end and the bound transmission channel, and then store the third execution result in the destination end, and send the third execution result to the service implementation layer when the service implementation layer requests to obtain the third execution result. In addition, the synchronization module in the source end may further execute the third command after receiving the third command, and store the third execution result in the synchronization module, and the service implementation layer of the main control device may directly read the third execution result stored in the synchronization module.

Please continue with fig. 5.

S504: the main control device determines first information to be closed from the L pieces of information to be closed.

In the embodiment of the present invention, after the main control device sends the third command to the L source ends through the service implementation layer, it is further required to know a result of the L source ends executing the third command, that is, whether the L source ends are successfully unbound, so that the main control device further reads the third execution result from the synchronization module of the source ends through the service implementation layer, and further determines the first information to be closed from the L pieces of information to be closed according to the third execution result. The first information to be closed refers to information to be closed, of which the corresponding source end is unsuccessfully unbound. The process of reading the third execution result by the main control device is similar to the process of reading the second execution result, and is not repeated here.

S505: and the main control device releases the transmission channel occupied by the first information to be closed.

In the embodiment of the invention, if a source end with a failed unbinding exists, in order to avoid that the source end continues to send data and further accesses an inaccessible area of a destination end, a transmission channel bound with the source end can be forcibly released through a main control device, and the released transmission channel is not used for transmitting the signal stream of the source end with the failed unbinding. After the master control device forcibly releases the transmission channel, it can consider that all source ends are successfully unbundled.

S506: and the master control device sends a fourth command to the K destination terminals through the service implementation layer.

The first command is used for instructing the K destination terminals to unbind the own receiving resources from the bound transmission channels. Referring to fig. 7, following the two examples of the information to be closed, fig. 7 is a schematic flow chart illustrating that the service implementation layer sends a fourth command to the destination 1 to the destination 4.

S5061: the service implementation layer sends a fourth command to the destination 1.

The fourth command received by the destination 1 is used to unbundle the receiving resource of the destination 1 from the transmission channel 1. The process of the service implementation layer sending the fourth command to the destination end is similar to the process of sending the first command to the destination end, and therefore, redundant description is not repeated here.

S5062: the service implementation layer receives the response message sent by the destination terminal 1.

Specifically, after receiving and storing the fourth command sent by the service implementation layer, the destination 1 feeds back a response message to the service implementation layer to notify the service implementation layer that the fourth command has been received by itself.

S5063: the service implementation layer sends a fourth command to the destination 2.

The fourth command received by the destination 2 is used to unbundle the receiving resource of the destination 2 from the transmission channel 1.

S5064: the service implementation layer receives the response message sent by the destination terminal 2.

Specifically, after receiving and storing the fourth command sent by the service implementation layer, the destination 2 feeds back a response message to the service implementation layer to notify the service implementation layer that the fourth command has been received by itself. It can be seen that, after knowing that the destination terminal 1 receives the fourth command, the master control device does not wait for the destination terminal 1 to complete the execution, but directly continues to send the fourth command to the destination terminal 2, so that different destination terminals can receive the fourth command in time, that is, different destination terminals can execute the fourth command in parallel, thereby reducing the waiting time of the master control device, and further reducing the total time consumed for switching the display scheme.

S5065: the service implementation layer sends a fourth command to the destination 3.

The fourth command received by the destination 3 is used to unbundle the receiving resource of the destination 3 from the transmission channel 2.

S5066: the service implementation layer receives the response message sent by the destination terminal 3.

Specifically, after receiving and storing the fourth command sent by the service implementation layer, the destination 3 feeds back a response message to the service implementation layer to notify the service implementation layer that the fourth command has been received by itself.

S5067: the service implementation layer sends a fourth command to the destination 4.

The fourth command received by the destination 4 is used to unbundle the receiving resource of the destination 4 from the transmission channel 2.

S5068: the service implementation layer receives the response message sent by the destination terminal 4.

Specifically, after receiving and storing the fourth command sent by the service implementation layer, the destination 4 feeds back a response message to the service implementation layer to notify the service implementation layer that the fourth command has been received by itself.

Please continue with fig. 5.

S507: and the main control device determines second information to be closed from the L pieces of information to be closed.

Specifically, the master control device may read a fourth execution result from the synchronization module of the source end through the service implementation layer, and then determine the second information to be closed from the L pieces of information to be closed according to the fourth execution result. The second information to be closed refers to information to be closed, of which the corresponding destination terminal has not successfully unbound. The process of reading the fourth execution result by the master control device is similar to the process of reading the first execution result, and is not repeated here.

S508: the master device releases the transmission channels except the transmission channel released in S505 in the L pieces of closing information.

Specifically, since in S505, part of the transmission channels have been released, the released transmission channels may be ignored here, and the remaining transmission channels except the transmission channels released in S505 may be released. In a specific implementation, all the transmission channels may be released directly in S508 without releasing the transmission channels in S505.

S509: the main control device feeds back the execution result of the starting command to the service management layer through the service implementation layer.

Specifically, after all the destination and source ends are unbound, the service implementation layer may feed back a start command execution result, that is, a result of closing signal stream transmission, to the service management layer, and then the service management layer may determine whether to display the next display scheme according to the result. In addition, the service implementation layer can also notify the service management layer of the device information of the source end and the destination end which are failed to unbind, so that the service management layer can notify the user control end in time, and a user can find a fault and arrange maintenance.

In the embodiment of the present invention, the signal stream transmission turning-on and turning-off methods may be used in combination. For example, when the existing display windows of the television wall are displayed, if switching to the next display scheme is required, the display windows currently being displayed need to be closed first by a signal stream closing method, that is, transmission of signal streams corresponding to the display windows is closed, and then transmission of a signal stream corresponding to the next display scheme is opened by a signal stream transmission opening method, so that the television wall displays the content of the next display scheme.

In summary, in the embodiment of the present invention, the main control device does not need to wait for the completion of all corresponding processes of one piece of opening information or information to be closed before executing the execution of the next piece of opening information or information to be closed, but directly sends the remaining opening information or information to be closed to the destination, so that all the destinations can perform binding or unbinding operations at the same time, and the source end is similar to the destination, thereby reducing the waiting time of the main control device, reducing the total time consumption for switching the display schemes, and improving the user experience quality.
