DETAILED DESCRIPTION OF THE EMBODIMENTS In order to make the technical solutions and advantages of the embodiments of the present invention more clearly, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The method for playing the patch data provided by the embodiment of the present invention includes first acquiring the patch data, and then playing the patch data while playing the network video.

1 is a flow chart of a method for playing patch data in an embodiment of the present invention. As shown in FIG. 1, the method for playing the patch data provided by the embodiment of the present invention includes two relatively independent steps:

Step S10: Acquire playback control data, and the to-be-played patch data indicated in the playback control data.

In order to ensure that the client can play the latest patch data in time while playing the video, the client first downloads related files, including patch data files and playback control data files, from the server. The patch data file may include one patch data or multiple patch data. When a tile data file contains multiple patch data, the patch data is a fixed whole. Here, the patch data file may be a file file such as a JPG, BMP, or the like, or an animation file such as a file in a format such as GIF or SWF, or a file in a multimedia file such as MPEG, AVI, WMV, or the like. The playback control data file includes playback control data, which may also be referred to as a playback control file.

The server side can manually or automatically update the patch data file as needed to ensure that the patch data file is always up to date. Here, after updating a patch data file on the server side of a patch data file, a check code is generated for the patch data file according to a predetermined algorithm, and each patch data file has a unique check code, and the check code is written. In the playback control file. In addition to the check code, the playback control file is more important to record the version number of the current playback control file and the identifier of each patch data file (not including the patch data file, only its logo), such as the patch. The file name of the data file, and the playback policy data for each tile data file.

Playing the policy data, indicating which channel each patch data file plays simultaneously with, playing order, display size, display position, playing time and playing time, etc. Specifically, the playing strategy of the audio patch data file includes: The sound size, rhythm change, etc. of the audio data. The playback strategy of the video tile data file can include:

A. The display size of the patch data playback window, the client displays the window of the patch data according to the size, and the widget data can be displayed with a relatively small window relative to the video screen size;

B. The motion mode in which the patch data appears dynamically, the client controls the motion mode when the patch data appears according to the specified motion mode, such as the rotation mode, the fade-out mode, the blind method, etc., to attract the user's attention;

C. The starting point and the ending position of the patch data playing window movement, the client controls the appearance position and the staying position of the patch data window according to the two positions, and the position of the playing window staying should be obvious but does not block the main video picture;

D. The playing time of the patch data, the client controls the playing time of the patch data according to the playing duration. When the time is up, the patch data window is hidden, and the appearance and disappearance of the patch data playing window can also be matched with the playing of the network video content. And ending, when playing the network video content, playing the patch data with the network video, and ending the playback of the patch data at the end of the network video;

E. The time interval for playing the next patch data, according to the time interval, the client controls the playing time of the next patch data, that is, the last patch data playback ends, and after the patch data playing window disappears, how long is the interval The next patch data window will automatically appear and play;

F. Whether the size of the patch data window is automatically scaled as the size of the video screen changes.

Of course, the playback strategy can also be changed according to actual needs.

In this way, when the client obtains the playback control file from the server, the client can control according to the playback. The file contains at least one identifier of the to-be-played tile data file to obtain at least one tile data to be played.

Step S30: The client controls to play the patch data. When the patch data is played, different play programs are called according to the format of the patch data file, and the step is followed in the played video according to the play policy data recorded in the play control file. The patch data acquired in S10.

2 is a flowchart of a method for acquiring a playback control file and a patch data file in the embodiment of the present invention. The method for obtaining a playback control file and a patch data file by the client in detail will be described below with reference to FIG. 2, as shown in FIG. 2, including :

Step S101: After the client starts, it is determined whether the playback control file already exists locally, if yes, step S103 is performed, otherwise step S102 is performed;

Step S102: The client downloads the latest playback control file from the server and stores it locally, and then performs step S106;

Step S103: The client reports the version number of the locally stored playback control file to the server or the server, and returns the version number of the latest playback control file to the client.

Step S104: The client or the server compares the version number of the playback control file of the client with the version number of the latest playback control file of the server, and determines whether the two are the same. If yes, step S106 is performed; otherwise, step S105 is performed;

Step S105: The client updates and downloads the latest playback control file, and stores it;

Step S106: Align the identifiers of the patch data files in the playback control file with the identifiers of the patch data files already existing in the client, and determine whether the client stores all the patch data that is the same as the identifier in the playback control file. Then step S108 is performed, otherwise step S107 is performed;

Step S107: downloading the patch data file that the client does not have the identifier in the playback control file, and then executing step S111;

Step S108: The client temporarily generates a check code for the patch data file stored in the client but identifies the patch data file recorded in the playback control file according to the check code algorithm predetermined by the server;

Step S109: comparing the check code of the patch data file in the playback control file one by one with the client side If the check code is generated, it is determined whether the two are the same, otherwise step S110 is performed, and then step S111 is performed; step S110: the client updates the patch data file with the same identifier but different check code from the server side, and The downloaded patch data file is stored on the client;

Step S111: The client clears the patch data file not recorded in the playback control file, and then executes step S30.

Of course, the server can also actively return to the client to play control files and / or patch data files. In the embodiment of the present invention, the server may generate a playback control file according to the personality data reported by the client, that is, select different to-be-played patch data files for the client and formulate different playback policy data according to different characteristics of the client. When the client does not report the personality data, the server generates a default playback control file for the client. The server uses the version number (such as when the playback control file was generated and the object) to distinguish between different playback control files generated for different clients. In the foregoing embodiment, in step S102 and S105, the client downloads the latest playback control file generated by the server for the client. In step S103, the server returns the latest playback generated for the client. Controlling the version number of the file; in step S104, the client or server compares the version number of the playback control file of the client with the version number of the latest playback control file generated by the server for the client.

3 is a flowchart of a client controlling a play patch data file according to an embodiment of the present invention. As shown in FIG. 3, the step of controlling a play patch data file specifically includes:

Step S301: extract the identifier of the patch data file to be played by each network video channel from the play control file, generate a patch data file identifier play queue for each channel, and store it in the memory of the client;

Step S302: Extract the play policy data corresponding to the play queue of the patch data file identifier from the play control file, form a queue, and store it in the client memory;

Step S303: When the video starts playing, according to the channel of the currently playing video, the above two queues are searched to obtain corresponding data required for playing;

In step S304, while playing the video, the corresponding play is called according to the obtained corresponding data. The program plays the patch data.

The server and the client for playing the patch data provided by the embodiment of the present invention are described below in conjunction with the method for playing the patch data provided by the embodiment of the present invention.

4 is a schematic structural diagram of a server in an embodiment of the present invention. As shown in FIG. 4, the server includes a play control file generating module 410, a database 411, a play control file version number comparison module 412, and a check code generating module 413.

The playback control file generating module 410 generates a playback control file, and stores the generated playback control file in the database 411. The database 411 stores the patch data file and the generated playback control file, and the check code generation module 413 performs each patch data file according to a predetermined verification algorithm after each patch data file in the database 411 of the server side is updated. Generate a check code and write the check code to the playback control file.

The play control file version number comparison module 412 receives the version number of the play control file from the client and compares it with the version number of the play control file in the database 411, when the version number or comparison of the play control file of the client is not obtained. When the result is different, the client is notified to download the latest playback control file.

Here, the server side may not need to play the control file version number comparison module 412. In this case, the database 411 directly returns the version number of the latest playback control file to the client.

5 is a schematic structural diagram of a client according to an embodiment of the present invention. As shown in FIG. 5, the client includes a database 510, an update download module 511, a patch data file identifier and a check code comparison module 512, and a check code generation module. 513. The play control module 514.

The database 510 stores the patch data file and the playback control file; when the playback control file is not played by itself, the update playback control file command is sent to the update download module; when the playback control file is stored by itself, the control data version number of the control data is reported to the server.

The update download module 511 downloads the play control file from the database 410 of the server to the database 510 according to the download instruction of the server, and then notifies the tile data file identification and check code comparison module 512. The patch data file identifier and check code matching module 512 compares the identifier of the patch data file stored in the database 510 with the downloaded play control file (the same version as the server-side playback control file) to be played. The identifier of the data file. When the comparison result is that the database 510 does not store all the to-be-played patch data files described in the playback control file, the update download module 511 is notified to download the patch data file recorded in the playback control file but not in the database 510; When the two are the same, the notification check code generating module 513 generates a check code for each local patch data file that is the same as the identifier in the playback control file according to the predetermined check code algorithm, and returns the check code generation module 513. The check code of the patch data file is compared with the check code of the patch data file recorded in the play control file in the database 510. When the check code is different, the update download module 511 is notified that the download identifier is the same but the check code is different. The patch data file, the update download module 511 downloads the patch data file and stores it in the database 510.

After the patch data file identification and check code matching module 512 receives the notification that the download is completed, the above-mentioned comparison operation is also performed.

After the latest playback control file and the to-be-played patch data file recorded in the playback control file are stored in the database 510, the update download module 511 instructs the database 510 to delete the patch data file stored in the database 510 but not belonging to the to-be-played.

The playing module 514 of the client is configured to extract, from the playing control file, the identifier of the patch data file that each channel needs to play, generate a patch data file playing queue for each channel, and store it in the database 510; The playback policy data of the tile data file to be played by each channel is extracted, formed into a queue, and stored in the database 510. The playing module 514 is further configured to: when starting the video playing, searching the two queues according to the currently playing channel to obtain corresponding data required for playing, and calling the corresponding playing program to play the patch data according to the obtained corresponding data.

For the case where the server does not play the control file version number comparison module 411, the client may further include a playback control file version number comparison module 515. In this case, the database 510 may not report its own playback control file version number to the server. , the playback control file version number comparison module 515 receives the latest playback control file version number from the server, and associates it with the database 510. The playback control file version number is compared, if the two are the same, the patch data file identifier and the check code comparison module 512 are notified for subsequent processing; if the two are different, the download update module 511 is notified from the server. The play control file is downloaded to the database 510 in the database 410, and then the patch data file identification and check code comparison module 512 is notified for subsequent processing.

The method for playing the patch data provided by the embodiment of the present invention, the server, and the client may set the patch data on the server side according to requirements, such as advertisements, news, announcements, etc., and may set the playback strategy of the patch data according to requirements. The operation is flexible. After the client obtains the patch data and the playback policy data, the patch video data can be played in another window while playing the network video program. Not only the playback mode is diverse, but also because the patch data has been downloaded to the local, it can also be guaranteed. Smooth playback of patch data. In particular, for the network live broadcast operator, the network live broadcast operator can place a patch advertisement on each program channel according to the needs of the present invention, and generate advertisement revenue when the user views the video.
