It is worth noting that the computer device 100 and the video playout server 200 are configured with a preset control protocol that is constructed based on preset length character encoding, the preset control protocol including a multi-file preload command and a multi-signal preload command.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a step of a video program processing method according to an embodiment of the present application, where the video program processing method can be implemented by the computer device 100 in fig. 1 as an execution main body, and the video program processing method is described in detail below.

Step S201, acquiring a program list to be broadcasted.

The program list to be broadcast comprises a plurality of programs to be broadcast, and the programs to be broadcast are configured with preloading preparation time and program broadcasting time.

Step S202, under the condition that the system time reaches the pre-loading preparation time configured by the target program to be broadcast, the program type of the target program to be broadcast is judged.

The target program to be broadcast is any one of a plurality of programs to be broadcast, and the program types of the programs to be broadcast comprise multi-file programs and multi-signal programs.

If the program type of the target program to be broadcast is a multi-file program, step S203 is executed.

Step S203, sending a multi-file preloading command to the video broadcast server 200, so that the video broadcast server 200 performs a first preloading operation on a plurality of files to be broadcast corresponding to the target program to be broadcast.

The first preloading operation is used for calling a file decoder of the video broadcasting server so as to decode a plurality of files to be broadcasted by using the file decoder.

If the program type of the target program to be broadcast is a multi-signal program, step S204 is executed.

Step S204, sending a multi-signal preloading command to the video broadcast server 200, so that the video broadcast server 200 performs a second preloading operation on a plurality of signals to be broadcast corresponding to the target program to be broadcast.

And the second preloading operation is used for calling a signal decoder of the video playing-out server so as to decode the plurality of signals to be played out by the signal decoder.

Step S205, when the system time reaches the program broadcasting time configured for the target program to be broadcasted and the preloading completion feedback of the video broadcasting server 200 is received, a broadcasting command is sent to the video broadcasting server 200, so that the video broadcasting server 200 broadcasts the target program to be broadcasted.

In the embodiment of the application, the preset control protocol is constructed based on UTF-8 (8-bit, Universal Character Set/Universal Transformation Format) coding, and the protocol constructed by the scheme has the characteristics of high flexibility, high safety, high compatibility and the like, and the length of the protocol Character string is not limited. Compared with the traditional VDCP limited byte instruction, the method is not suitable for complex instructions and scenes controlled by a network. The character length of the preset control protocol provided by the embodiment of the application is not limited, the protocol adopts network character strings, and the operation is flexible and convenient. Based on this, multi-file type programs or multi-signal type programs in the related art can be processed.

In order to more clearly describe the scheme provided by the embodiment of the present application, for example, the preset control protocol provided by the embodiment of the present application may be defined by the following command specification: 1) UTF-8 encoding; 2) each command takes the carriage return line feed character as a terminator; 3) the command does not distinguish case; 4) the command parameters are separated by spaces, and if a certain parameter contains a space, the parameter is included by a quotation mark; 5) the special sequence is as follows: the parameters are enclosed by quotation marks, and the quotation marks in the parameters are represented by escape sequences. The universal escape character is backslash. The commonly used escape sequence is suggested as follows (avoiding the use of special characters): \\ quotation mark; \ \ reverse slash; \\ n line feed; 6) comma separation is used between the command pending values.

Based on the command specification, the preset control protocol provided in the embodiment of the present application can implement processing of multiple file programs or multiple signal programs, and can implement operations only according to multiple file preloading commands or multiple signal preloading commands, without an additional protocol or sending commands multiple times, and only one command needs to be sent, so that the video broadcast server 200 can expand the processing function of multiple file programs or multiple signal programs. It should be understood that, when an actual program is broadcast, each program to be broadcast in the program list to be broadcast may be broadcast through the above scheme, and after the current target program to be broadcast is broadcast, the above steps may be repeated until the unicast of the whole program to be broadcast is completed.

In one possible embodiment, the video playout server 200 comprises a plurality of video playout channels, and the multi-file preload command comprises channel allocation rules;

the aforementioned step S203 may be implemented by performing the following detailed steps.

And a substep S203-1, sending a multi-file preloading command to the video broadcasting server 200, so that the video broadcasting server 200 caches a plurality of files to be broadcasted to a plurality of video broadcasting channels according to a channel allocation rule, and calling a file decoder.

The aforementioned step S204 may be implemented by performing the following detailed steps.

And a substep S204-1, sending a multi-signal preloading command to the video broadcasting server 200, so that the video broadcasting server 200 performs signal address acquisition on a plurality of signals to be broadcasted in a plurality of video broadcasting channels according to a channel allocation rule, and calls a signal decoder.

In order to more clearly describe the scheme provided by the embodiment of the present application, the multi-file preloading command and the multi-signal preloading command included in the preset control protocol may be referred to as preload command LOADBG, and the syntax structure may be as follows:

LOADBG[channel：int]{-[layer：int]}[clip：string]{SEEK[frame：int]}{LENGTH[frames：int]}{[loop：LOOP]}

[ channel: int ] { [ layer: int ] } channel: a channel number;

[ clip: string ]: name of material

Based on this, taking the program to be broadcast as an 8K program as an example, the multi-file preloading command may be represented by the following form:

LOADBG 1 layers{10：xxxx；11：xxxx；12：xxxx；13：xxxx}list

wherein xxxx is 4K file names. Therefore, the aim of caching a plurality of files to be played to a plurality of video playing channels is fulfilled.

The multi-signal preload command may be represented by the following form:

Loadbg 1-10 matrox xxxx

Loadbg 1-11 matrox xxxx

Loadbg 1-12 matrox xxxx

Loadbg 1-13 matrox xxxx

wherein xxxx is specific parameter information, including an output card, an IP address, a port number, and the like, and examples are as follows:

card 0 sdi 02110 vbitecount 10 depth-frames 6 igmpv3 inclusion duplication retry 0 srcap 192.168.0.10 video objects "multiaddress 238.0.1.1 port 10000" audioareas "multiaddress 238.0.1.2 port 10000 aupktdur 1 usertkcnt false trkcnt 2" ancars "multiaddress 238.0.1.3 port 10000" ratio 16: 9 format 2160p5000 channel _ layout 8ch redundancy true srcap _ r 192.168.0.20 video areas _ r "multiaddress 238.1.1.1 port 10000" audioareas _ r "multiaddress 238.1.1.2 port 10000" ancargs _ r "multiaddress 238.1.1.3 port 10000. Therefore, the aim of acquiring the signal addresses of a plurality of signals to be played in a plurality of video playing channels is fulfilled.

In a possible implementation manner, the preset control protocol further includes a single file preloading command and a single signal preloading command, and the program types of the programs to be broadcast further include single file type programs and single signal type programs.

Step S206, if the program type of the target program to be broadcast is a single file program, sending a single file preloading command to the video broadcast server 200, so that the video broadcast server 200 performs a first preloading operation on the file to be broadcast corresponding to the target program to be broadcast.

Step S207, if the program type of the target program to be broadcast is a single signal program, sending a single signal preloading command to the video broadcast server 200, so that the video broadcast server 200 performs a second preloading operation on the signal to be broadcast corresponding to the target program to be broadcast.

In this embodiment of the application, the preset control protocol constructed in the foregoing may also implement processing of a single file type program or a single signal type program, and on the basis of the foregoing command rule, taking an example that a program to be played is an 8K program, a single file preloading command may be represented in the following form:

LOADBG 1-10：xxxx

wherein xxxx is the name of the 8K file. Therefore, the aim of caching the file to be played in the video playing channel is fulfilled.

The single signal preload command may be represented by the following form:

LOADBG 1-10 matrox xxxx

where xxxx represents the specific parameter information required such as:

card 0 sdi 02110 vbitecount 10 depth-frames 6 igmpv3 inclusion duplication retry 0 srcap 192.168.0.10 video objects "multiaddress 238.0.1.1 port 10000" audioareas "multiaddress 238.0.1.2 port 10000 aupktdur 1 usertkcnt false trkcnt 2" ancars "multiaddress 238.0.1.3 port 10000" ratio 16: 9 format 2160p5000 channel _ layout 8ch redundancy true srcap _ r 192.168.0.20 video areas _ r "multiaddress 238.1.1.1 port 10000" audioareas _ r "multiaddress 238.1.1.2 port 10000" ancargs _ r "multiaddress 238.1.1.3 port 10000. Therefore, the aim of acquiring the signal address of the signal to be played in the video playing channel is fulfilled.

In a possible implementation manner, the preset control protocol further includes a teletext rendering command and a teletext clearing command, and the following implementation manner is further provided in an embodiment of the present application.

And step S208, obtaining the image-text rendering file.

The image-text rendering file comprises rendering parameters and images and texts to be rendered.

Step S209, sending an image-text rendering command to the video broadcast server 200 when the first preset condition is met, so that the video broadcast server 200 renders the image-text to be rendered into the display frame of the target program to be broadcast according to the rendering parameter.

Step S210, sending an image-text clearing command to the video broadcasting server 200 when a second preset condition is met, so that the video broadcasting server 200 clears the image-text to be rendered from the display picture of the target program to be broadcasted according to the image-text to be rendered.

In the functions that the video broadcasting server 200 needs to expand at present, the image-text rendering is a relatively important function, and when the image-text display needs to be additionally performed in the display picture of the target program to be broadcasted, for example, the image-text of a certain television station logo or an advertisement of a certain sponsor can be realized by utilizing the image-text rendering command and the image-text clearing command which are included in the preset control protocol. On the basis of the aforementioned command specification, the syntax structure of the teletext rendering command CG and the teletext clear command CG may refer to:

CG[video_channel：int]{-[layer：int]}[add|remove]

[layer：int][parament：string]

it should be understood that the teletext rendering commands CG in the embodiments of the application can be directly validated without performing the aforementioned preloading and playing operations of the program to be broadcast. In order to more clearly describe the scheme provided by the embodiment of the present application, the following describes the use of the graphics-text rendering command CG in detail.

(1) And (3) making the prepared html5 page and all the related files used by the page into a picture-text rendering file, (the name of the picture-text rendering file is the same as that of the html5 page), and putting the picture-text rendering file into a template directory of the integrated video server, for example: the folders of cctv8klogo, shizhong and the like respectively comprise corresponding html5 pages and reference files thereof. In other embodiments of the embodiment of the present application, the production of the image-text rendering file may also be completed on the computer device 100, and the manner of obtaining the image-text rendering file is not limited herein.

(2) Sending a graphics rendering command CG to a video server, for example, there may be a command CG 1-100add 1 "cctv 8klogo/cctv8 klogo" 1, where the command sends a graphics rendering command to the all-in-one broadcast video server 2001, and indicates that html5 page CG 1-100add 2 "shizhong/shizhong" 1, which is the html 8klogo rendered on the first layer of CEF of 100 layers of video, sends a graphics rendering command to the all-in-one broadcast video server 2001, and indicates that html5 page shizhong is rendered on the second layer of CEF of 100 layers of video, and other pages are the same and are not described herein again.

For the teletext command CG, reference is instead made to the following example:

CG 1-100remove 1 (or 2)

The instruction clears the html5 page rendering for that layer.

STOP 1-100

The command stops the video layer where the entire teletext is located and all teletext is removed.

For the above-mentioned teletext and teletext command, where 1 denotes the first video broadcast channel, 100 is the video layer, the layer number can be customized, add denotes the upper teletext layer, 1 denotes that the layer number of the html5 page in CEF can be filled in freely but is unique (it is suggested to increase in order from 1), "the content is html5 page name (including folder and file name without suffix). For CG 1-100remove 1, where remove represents the lower teletext layer, the others are as above. For STOP 1-100 it is actually the STOP play-out command in the set of play-out commands. For teletext commands, which all start with a CG and take effect immediately, there is no preload and playout logic.

Through the grammar structure, the image-text rendering can be realized when a user needs to add the trademark of the sponsor of the program on the display picture of the target playing program being played (a first preset condition), and the image-text clearing can be realized when the user switches to the next program and needs to remove the trademark of the sponsor of the previous program (a second preset condition).

In a possible implementation manner, the preset control protocol further includes a pause playback command and a resume playback command, and the following implementation manner is further provided in an embodiment of the present application.

Step S211, when the third preset condition is satisfied, sends a pause playing command to the video broadcast server 200, so that the video broadcast server 200 pauses the display screen of the target program to be broadcast.

In step S212, when the fourth preset condition is satisfied, a continue playing command is sent to the video broadcast server 200, so that the video broadcast server 200 continues to play the display picture of the target program to be broadcast.

On the basis of the foregoing, the syntax structure of the preset control protocol further including the PAUSE playback command PAUSE and the RESUME playback command RESUME provided in the embodiment of the present application may refer to the following example.

PAUSE[video_channel：int]{-[layer：int]|-0}。

RESUME[video_channel：int]{-[layer：int]|-0}。

In the embodiment of the present application, when a user needs to pause a program being played, for example, the playing content needs to be confirmed (a third preset condition), or resume playing from a paused state, for example, the playing content is determined to be correct (a fourth preset condition), the above syntax structure can be used to implement the method.

In a possible implementation manner, the preset control protocol further includes a clear program command, and the following implementation manner is further provided in an embodiment of the present application.

Step S213, sending a program clearing command to the video broadcast server 200 when the fifth preset condition is met, so that the video broadcast server 200 clears the relevant data of the target program to be broadcast.

On the basis of the foregoing, the syntax structure of the preset control protocol including CLEAR program command CLEAR may be as follows:

CLEAR[video_channel：int]{-[layer：int]}

for example, when the video channel 1 of the video playout server 200 needs to be cleared (fifth preset condition), "CLEAR 1" may be configured, which enables removing foreground and background material of all layers of the channel 1. More elaborate operations can be implemented, for example, CLEAR 1-10 can only remove all material at layer 10 of channel 1, which is not possible with the existing control protocol for the video playback server.

In a possible implementation manner, the preset control protocol further includes a server status query command, a media file query command, and a program status query command, and the following implementation manners are further provided in an embodiment of the present application.

In step S214, when the sixth preset condition is satisfied, a server status query command is sent to the video broadcast server 200, so that the video broadcast server 200 feeds back the channel status of the video broadcast server 200.

Step S215, sending a media file query command to the video broadcast server 200 when a seventh preset condition is met, so that the video broadcast server 200 feeds back multimedia information of a program to be broadcast;

in step S216, when the eighth preset condition is met, a program status query command is sent to the video broadcast server 200, so that the video broadcast server 200 feeds back whether the program to be broadcast is ready for preloading.

In addition to the commands included in the preset control protocol provided above, the embodiments of the present application also provide a server status query command INFO, a media file query command CLS, and a program status query command CINF, and the following examples may be referred to for syntax structures of the three.

INFO [ video _ channel: int ] { [ layer: int ] }, through the syntax structure, the channel of the video broadcast server 200 or the information of the channel-designated layer can be obtained, and if the layer is not designated, the information of the whole channel is returned.

CLS { [ sub _ direction: string ] }, through the syntax structure, all media file information under the media path of the video broadcast server 200 can be acquired, and if a sub _ direction is specified, only the media file information under the sub _ direction is returned.

CINF [ filename: string ], through this syntax structure, all file information named file under the media path of the video playout server 200 can be obtained, and the file information format is: filename material type file size file modify time material duration time _ bas.

In addition, the preset control protocol provided in the embodiment of the present application can also complete the basic PLAY command PLAY and the STOP PLAY command STOP, and the following examples can be referred to for syntax structures of the two commands.

PLAY [ video _ channel: int ] { [ layer: int ] | -0} { [ clip: string ] } { "additional parameters" } through the syntax structure, the material, i.e. the program to be broadcast, can be played.

STOP [ video _ channel: int ] { [ layer: int ] | -0}, and through the grammar structure, the foreground playing material of the specified layer can be removed, namely, the playing is stopped.

In order to more clearly describe the scheme provided in the embodiment of the present application, please refer to fig. 3, and fig. 3 is a schematic diagram of an overall structure of the video program processing system provided in the embodiment of the present application, where the computer device 100 may be an integrated broadcast controller 1001, the video broadcast server 200 may be an integrated broadcast video server 2001, the two are communicatively connected through a broadcast Control switch 300, the MIXER is a modulator, the Stream is a signal Stream, the file is a file, the OUTPUT is a video OUTPUT unit, the ge is a coordination unit, the consum is a user allocation unit, and the Frame Rate Control is a Rate controller.
