In the embodiment of the invention, under the condition that the decoding speed of the decoder is not equal to that of the video wall client, in order to synchronize the video played by the video wall client and the video played by the video wall, in the process of playing the video, the video wall client can also send the playing progress acquiring request of the video to be played to the video wall server, so that the playing progress acquiring request of the video to be played is sent to the decoder through the video wall server, and then the decoder acquires the playing progress information of the video to be played based on the playing progress acquiring request and sends the playing progress information of the video to be played to the video wall client, so that the video wall client can conveniently adjust the playing progress of the video wall client.

It should be noted that the video wall client may forward the request for obtaining the playing progress of the video to be played to the decoder through the video wall server, or may directly send the request for obtaining the playing progress of the video to be played to the decoder, which is not limited in the embodiment of the present invention.

In step 509, the video wall server receives a request for acquiring the playing progress of the video to be played sent by the video wall client, and records the request for acquiring the playing progress.

The video wall server receives a playing progress acquiring request of a video to be played, which is sent by the video wall client, and records the playing progress acquiring request, so that the playing progress acquiring request can be conveniently inquired subsequently, and the video playing information of the video to be played can be obtained.

In the embodiment of the present invention, the video wall server may record the request for obtaining the playing progress in a specified file. The designated file is the same file as the designated file where the control information is located.

And step 510, the video wall server sends a playing progress acquisition request to a decoder.

And 511, the decoder acquires the playing progress information of the video to be played based on the playing progress acquisition request. The playing progress information of the video to be played is used for indicating the playing progress of the video to be played by the decoder.

For example, the decoder may obtain the playing progress information of the video to be played in the following 3 ways:

in the first way, the decoder may obtain a frame number of a currently played video frame, and determine the playing progress information of the video to be played based on the obtained frame number. For example, the frame number of the currently played video frame obtained by the decoder is 011, and after the decoder obtains the playing progress information, the decoder needs to send the playing progress information to the tv wall client through the tv wall server, so to improve the accuracy of the tv wall client in adjusting the playing progress of the tv wall client, the decoder may process the obtained frame number, for example, the frame number of the frame number 011 obtained by the decoder is 012, and then the decoder may determine the frame number 012 as the playing progress information of the video to be played.

In the second manner, the decoder may obtain a frame number of a previous video frame and a frame number of a next video frame of a currently played video frame, and determine the playing progress information of the video to be played based on the obtained frame number of the previous video frame and the obtained frame number of the next video frame.

For example, the frame number of the currently played video frame is 011, the frame number of the previous video frame is 010, and the frame number of the next video frame is 012, and after the decoder acquires the playing progress information, the decoder needs to send the playing progress information to the tv wall client through the tv wall server, so that in order to improve the accuracy of the tv wall client in adjusting the playing progress of the tv wall client, the decoder can process the two acquired frame numbers, and determine the processed frame number as the playing progress information of the video to be played. For example, the decoder may determine the frame number 011 after the frame number 010 and the frame number 013 after the frame number 012 as the play progress information of the video to be played.

In the third mode, the decoder may obtain the playing time length of the video to be played, and determine the playing progress information of the video to be played based on the obtained playing time length. Similarly, in order to improve the accuracy of the television wall client for adjusting the playing progress of the television wall client, the decoder may process the acquired playing time, and determine the processed playing time as the playing progress information of the video to be played. For example, if the playing time duration obtained by the decoder is 10 minutes, the decoder may determine 10 minutes and 30 seconds as the playing progress information of the video to be played.

And step 512, the decoder sends the playing progress information of the video to be played to the video wall server.

The decoder sends the playing progress information of the video to be played to the television wall server, and the playing progress information of the video to be played is sent to the television wall client through the television wall server.

It should be noted that the decoder may forward the playing progress information of the video to be played to the video wall client through the video wall server, or may directly send the playing progress information of the video to be played to the video wall client, which is not limited in the embodiment of the present invention.

And 513, the video wall server receives the playing progress information of the video to be played sent by the decoder, and records the playing progress information.

The video wall server receives the playing progress information of the video to be played sent by the decoder and records the playing progress information, so that the playing progress information can be conveniently inquired subsequently, and the related information of the playing progress of the video to be played can be obtained.

For example, the tv wall server may record the playing progress information in a designated file. The designated file is the same as the designated file where the control information and the playing progress acquisition request are located. By inquiring the specified file, more video playing information about the video to be played can be obtained.

And step 514, the television wall server sends the playing progress information to the television wall client.

Step 515, when the first playing progress of the video to be played by the tv wall client is not equal to the playing progress indicated by the playing progress information, the tv wall client adjusts the first playing progress to the playing progress indicated by the playing progress information.

The mode of determining the first playing progress of the video to be played by the video wall client and the mode of determining the playing progress information of the video to be played by the decoder can be the same. For example, the video wall client may determine the first playing progress of playing the video to be played in the following two 3 ways.

In the first mode, the video wall client may obtain a play frame number of a video frame of a currently played video, and determine the obtained frame number as a first play progress of playing the video to be played.

In the second mode, the video wall client may obtain a frame number of a previous video frame and a frame number of a next video frame of a currently played video frame, and determine a first playing progress for playing the video to be played based on the obtained frame number of the previous video frame and the obtained frame number of the next video frame.

In a third manner, the video wall client may obtain a playing time length of the video to be played, and determine a first playing progress of playing the video to be played based on the obtained playing time length.

After determining a first playing progress of playing the video to be played, the video wall client compares the first playing progress with the playing progress indicated by the playing progress information. When the first playing progress of the video to be played by the television wall client is not equal to the playing progress indicated by the playing progress information, the television wall client adjusts the first playing progress to the playing progress indicated by the playing progress information.

For example, the decoder determines the playing progress information of the video to be played based on the frame number of the currently played video frame, the video wall client determines the first playing progress of the video to be played based on the frame number of the currently played video frame, and if the frame number of the currently played video frame acquired by the video wall client is 08 and the frame number in the playing progress information received by the video wall client and sent by the decoder is 012, the video wall client may adjust the currently played video frame to the video frame with the frame number of 012 in order to ensure that the video wall client and the video wall play synchronously.

For another example, the decoder determines the playing progress information of the video to be played based on the frame number of the previous video frame and the frame number of the next video frame of the currently played video frame, and the video wall client determines the first playing progress of the video to be played based on the frame number of the currently played video frame, assuming that the frame number of the currently played video frame acquired by the video wall client is 08, and the frame numbers in the playing progress information received by the video wall client and sent by the decoder are 011 and 013, then, in order to ensure that the video wall client and the video wall play are synchronized, the video wall client may adjust the currently played video frame to the video frame with the frame number of 012.

For another example, the decoder determines the playing progress information of the video to be played based on the playing time of the video to be played, the video wall client determines the first playing progress based on the playing time of the video to be played, and if the playing time of the video to be played acquired by the video wall client is 8 minutes and the playing time in the playing progress information sent by the decoder and received by the video wall client is 10 minutes and 30 seconds, the video wall client may adjust the current playing time to 10 minutes and 30 seconds and start playing the video at 10 minutes and 30 seconds in order to ensure that the video wall client and the video wall are played synchronously.

In the embodiment of the present invention, the decoder and the video wall client may also determine the playing progress based on the progress information indicated by the playing progress bar. For example, assuming that the playing progress of the video to be played by the decoder (i.e., the playing progress indicated by the playing progress information) is 50%, and the first playing progress of the video to be played by the video wall client is 48%, since the first playing progress of the video to be played by the video wall client is not equal to the playing progress indicated by the playing progress information, the television wall client may adjust the first playing progress to the playing progress indicated by the playing progress information, and further synchronize the video played by the video wall client with the video played by the video wall.

In the related art, when the decoding speed of the video wall client is not equal to the decoding speed of the decoder, for example, when the decoding speed of the video wall client is greater than the decoding speed of the decoder, the speed of the video to be played by the video wall client is greater than the speed of the video to be played by the video wall, and a phenomenon that the video wall client continues to acquire video data from the video-on-demand server and copies the video data to the decoder, but the decoder does not receive the video data sent by the video wall client may occur, so that the video data is lost, a video skip second phenomenon occurs, and the video played by the video wall client is not synchronized with the video played by the video wall. In the embodiment of the invention, even if the decoding speed of the video wall client is greater than that of the decoder, the video wall client can adjust the first playing progress to the playing progress of the video to be played by the decoder, so that the synchronization between the video played by the video wall client and the video played by the video wall can be ensured.

It should be noted that, in the embodiment of the present invention, the decoder may also obtain, through the video wall server, the playing progress information of the video to be played by the video wall client, where the playing progress information is used to indicate the playing progress of the video to be played by the video wall client. When the second playing progress of the video to be played by the decoder is not equal to the playing progress of the video to be played by the television wall client, the decoder can adjust the second playing progress to the playing progress of the video to be played by the television wall client, so that the synchronization between the video played by the television wall client and the video played by the television wall is ensured. For example, when the decoding speed of the decoder is higher than that of the video wall client, the speed of playing the video to be played by the video wall is higher than that of playing the video to be played by the video wall client, and a phenomenon that a local buffer area of the decoder is empty may occur in the related art, which may finally cause the video wall to play suddenly in advance of the video wall client for a period of time to generate a black screen, and the video data sent by the video wall client is continuously played when the video data is received again. In the embodiment of the invention, even if the decoding speed of the decoder is higher than that of the television wall client, the second playing progress can be adjusted to be the playing progress of the video to be played by the television wall client by the decoder, so that the phenomenon of black screen of the television wall can be avoided, and the synchronization between the video played by the television wall client and the video played by the television wall is ensured.

In summary, in the video playing method provided by the embodiment of the present invention, the decoder obtains the video data from the vod server based on the storage path in the control information, and then outputs the video data and the control information to the tv wall, since the decoder can directly obtain the video data from the vod server based on the storage path in the control information, without obtaining the video data from the tv wall client, therefore, the influence of the working state of the television wall client on the video playing of the television wall is avoided, therefore, the picture quality of the video to be played by the television wall is improved, and when the first playing progress of the video to be played by the television wall client is not equal to the playing progress indicated by the playing progress information, the video wall client can adjust the playing progress of the local playing video to be played according to the current playing progress of the decoder, and further enables the video wall client to play the video and the video wall to play the video synchronously.

And step 606, the video wall client acquires the video data from the video-on-demand server based on the storage path in the control information.

Step 607, the video wall client plays the video to be played based on the video data.

Step 608, in the process of playing the video to be played on the video wall, the video wall client sends the video playing instruction for the video to be played to the video wall server.

The video playing instruction is used for instructing the decoder to control the playing state of the video to be played. For example, the video playing instruction may be a playing instruction, a pause instruction, a close instruction, a positioning instruction, a fast forward instruction, a fast rewind instruction, or the like.

It should be noted that the video wall client may forward the video playing instruction for the video to be played to the decoder through the video wall server, or may directly send the video playing instruction for the video to be played to the decoder, which is not limited in the embodiment of the present invention.

And step 609, the video wall server receives a video playing instruction aiming at the video to be played and sent by the video wall client, and records the video playing instruction.

The video wall server receives a video playing instruction aiming at the video to be played and sent by the video wall client, and records the video playing instruction, so that the video playing instruction can be conveniently inquired subsequently, and the video playing information of the video to be played can be obtained.

In the embodiment of the invention, the video wall server can record the video playing instruction in the specified file. The designated file is the same as the designated file where the control information of the video data of the video to be played and the playing progress acquisition request of the video to be played are located.

In the embodiment of the present invention, since more video playing information related to the video to be played passes through the video wall server, for example, the video playing information may be: the video playing information can be stored by the video wall server aiming at the video playing instruction of the video to be played, the control information of the video data of the video to be played and the playing progress acquiring request of the video to be played, so that the video playing information can be directly acquired subsequently when needed, and the video can be played again.

And step 610, the video wall server sends the video playing instruction to a decoder.

In this step, the video wall server transparently transmits the video playing command to the decoder.

Step 611, the decoder controls the playing status of the video to be played based on the video playing instruction.

For example, assuming that the video playing instruction is a pause instruction, the decoder may control the video to be played to be in a pause state based on the pause instruction.

In summary, in the video playing method provided in this embodiment, the video wall server receives the control information of the video data of the video to be played, which is sent by the video wall client, sends the control information to the decoder, and records the control information, so that the decoder obtains the video data from the vod server based on the storage path in the control information.
