The streaming server 504 is configured to receive the request information sent by the device 403 for recording video-on-demand breakpoint information, and send the sliced video files required by the video playback terminal 401 to the video playback terminal 401 according to the request information.

In an embodiment of the present invention, the device for recording video-on-demand breakpoint information may be implemented by a session resource management server (Sessions Resources Management, SRM).

In the following, the method for recording video-on-demand breakpoint information provided by the embodiment of the present invention will be further described in combination with the device and system for recording video-on-demand breakpoint information provided by the above-mentioned embodiments, taking the user interrupting watching a certain video as an example. As shown in Figure 7, one embodiment of the present invention provides a kind of method for recording video-on-demand breakpoint information, and this method may comprise the following steps:

Step 701: Receive the request information of the video player terminal to obtain the index file, and deliver the index file.

In one embodiment of the present invention, when a user wants to watch a video, he selects the video to watch on the navigation page provided by the video playback terminal, and performs on-demand broadcasting of the video. After the user orders the video, the video player terminal sends a request message to the device that records the video-on-demand breakpoint information. The purpose of the request message is to obtain the index file of the video to be watched. After the device that records the video-on-demand breakpoint information receives the request , obtain the required index file from the streaming server, and send the obtained index file to the video playback terminal.

For example, user A wants to watch movie B on notebook computer 1, then user A directly selects movie B on the navigation page provided by notebook computer 1, or searches for movie B through the search function, and orders movie B. The device for recording video-on-demand breakpoint information is realized by the session resource management server SRM. The notebook computer 1 sends the request information for obtaining the index file M3U8 of movie B to the session resource management server SRM. After receiving the request information, the session resource management server SRM, Obtain the required index file M3U8 from the streaming server, and send the obtained index file M3U8 to the notebook computer 1 .

Step 702: Receive the request information sent by the video playback terminal to obtain the sliced video file, and determine whether the time from the last time the request information is received to the current time exceeds the preset timeout period, if yes, execute step 703, otherwise continue to execute the step 702.

In one embodiment of the present invention, when the video playback terminal is playing a video file, the video file is sent from the streaming server to the video playback terminal in the form of sliced video files, each sliced video file includes a section of video data, and the index file contains The index directory of each slice video file corresponding to the video file and the sequence of each slice video file are recorded. After receiving the index file, the video playback terminal sends request information for obtaining sliced video files to the device that records the video-on-demand breakpoint information in sequence according to the index file. When the video playback terminal pauses playing the video file or exits the video player, the video playback terminal It will stop sending request information for obtaining segmented video files to the device that records video-on-demand breakpoint information. The device for recording video-on-demand breakpoint information receives in real time the request information sent by the video player terminal to obtain sliced video files, and judges whether the time from the last time the request information sent by the video player terminal to the current time exceeds the preset timeout time, if yes, determine that the video playback terminal has stopped playing the video file, and execute step 703 accordingly; otherwise, determine that the video playback terminal is still playing the video file, and continue to execute 702.

For example, according to the obtained index file M3U8, the notebook computer 1 sends to the session resource management server SRM sequentially the request information for obtaining the sliced video files from the header of movie B to the sliced video files at the end. The sending process of the request information is similar to that of the notebook computer 1. The video playing process is performed synchronously. When the notebook computer 1 stops playing the video, the request information for obtaining the video file of the video slice also stops sending. The session resource management server SRM receives the request information sent by the notebook computer 1 in real time, and judges whether the time from the last time the request information is received to the current time exceeds the preset timeout time of 1 minute, and if so, determines that the notebook computer 1 has stopped playing movie B , execute step 703 accordingly; if not, determine that the laptop computer 1 is still playing movie B, and continue to execute step 702.

Step 703: Generate breakpoint information according to the latest received request information.

In one embodiment of the present invention, after determining that the time from the last time the request information was received to the current time exceeds the preset timeout time, the device for recording video-on-demand breakpoint information analyzes the latest request information received, Obtain therefrom the user ID logged on the video playback terminal, the ID of the video file to be obtained by the request information, and the time stamp of the starting position of the sliced video file to be obtained, and form a segment including the user ID, video file ID and time stamp. point information.

For example, after the session resource management server SRM receives the request information 1 sent by the notebook computer 1, it does not receive the request information sent by the notebook computer 1 to obtain the sliced video file of movie B within 1 minute, and the session resource management server SRM responds to the request The information 1 is analyzed, and the user ID-A of user A logged in on the notebook computer 1 is obtained, the video file ID-B of the movie B played on the notebook computer 1 is obtained, and the start of the sliced video file to be acquired is obtained. The time stamp of the location is 30 minutes, forming a breakpoint information 1 including user ID-A, video file ID-B and a time stamp of 30 minutes. Through the breakpoint information 1, it can be determined that user A has watched movie B for 30 minutes.

Step 704: Store the formed breakpoint information into the breakpoint information database.

In one embodiment of the present invention, after the device for recording video-on-demand breakpoint information forms the breakpoint information, it determines whether there is a user corresponding to the breakpoint information to be stored in the breakpoint information database for storing the breakpoint information. ID and other breakpoint information of the same video file ID, if so, cover the breakpoint information corresponding to it with a user ID and the same video file ID with the breakpoint information to be stored, be responsible for directly the pending The stored breakpoint information is stored in the breakpoint information database.

For example, after the breakpoint information 1 is formed, it is judged whether the breakpoint information database in which the user stores the breakpoint information includes a breakpoint information 2 that both includes the user ID-A and the video file ID-B with the breakpoint information 1. If the point information 2 exists, cover the breakpoint information 2 with the breakpoint information 1; if the breakpoint information 2 does not exist, directly store the breakpoint information 1 in the breakpoint information database.

It should be noted that after the device for recording video-on-demand breakpoint information receives the request information sent by the video playback terminal to obtain sliced video files, it will send the obtained request information to a streaming server with the lowest load. According to the received request information, the sliced video files required by the video playback terminal are directly sent to the video playback terminal.

In the following, the user continues to watch a video file as an example to describe the method of using the breakpoint information. As shown in Figure 8, an embodiment of the present invention provides a method for using breakpoint information, including:

Step 801: Obtain the index file of the video file to be played continuously.

In one embodiment of the present invention, after the user logs in at a video playback terminal through the user ID, the device for recording video-on-demand breakpoint information searches whether there is breakpoint information corresponding to the user ID from the breakpoint information database, and if so, The breakpoint information is sent to the video playback terminal, and the video playback terminal shows the user the video that can be continued to play and the playback progress. After obtaining the confirmation information of the user's continued playback, the video playback terminal sends the device that records the video-on-demand breakpoint information. After receiving the request information, the device for recording video-on-demand breakpoint information obtains the required index file from the push streaming server, and sends the obtained index file to the video playback terminal.

For example, in the embodiment shown in FIG. 7 , user A has watched movie B on laptop computer 1 for 30 minutes before, and breakpoint information 1 is formed and stored in the breakpoint information database. User A logs in user ID-A on mobile phone 1 again, and the session resource management server SRM detects that breakpoint information 1 corresponding to user ID-A exists in the breakpoint information database, and then sends breakpoint information 1 to mobile phone 1, and mobile phone 1 According to the breakpoint information 1, it is shown to user A that movie B can be played continuously from 30 minutes. After receiving confirmation from user A that movie B can be played continuously, mobile phone 1 sends the index file M3U8 of movie B to the session resource management server SRM. Request information. After receiving the request information, the session resource management server SRM obtains the required index file M3U8 from the streaming server, and sends the obtained index file M3U8 to the mobile phone 1 .

Step 802: The video playback terminal continuously sends request information for obtaining segmented video files to the device for recording video-on-demand breakpoint information according to the index file.

In one embodiment of the present invention, after receiving the index file, the video playback terminal starts from the position of the time stamp recorded in the received breakpoint information according to the order of the sliced video files recorded in the index file, and proceeds sequentially to The device for recording video-on-demand breakpoint information sends request information for obtaining each segmented video file after the time stamp position.

For example, the mobile phone 1 sends request information to the session resource management server SRM to acquire each sliced video file after the 30th minute of the movie B according to the order of the sliced video files of the movie B recorded in the index file M3U8.

Step 803: The device for recording video-on-demand breakpoint information sends the received request information to the streaming server with the least load.

In one embodiment of the present invention, the device for recording video-on-demand breakpoint information obtains the network output bandwidth occupancy of each streaming server in the streaming streaming server cluster and the disk output bandwidth occupancy of each streaming streaming server in the streaming streaming server cluster after receiving the request information for obtaining sliced video files sent by the video playback terminal. I/O speed, determine the load of each streaming server in the streaming server cluster according to the obtained network output bandwidth occupation and disk I/O speed, and send the received request information to the streaming streaming server with the smallest load. The device for recording video-on-demand breakpoint information will also judge whether the time from the last time the request information is received to the current time exceeds the preset timeout period to determine whether to form breakpoint information. The specific process is the same as the method shown in Figure 7 Same, no more details here.

For example, the streaming server cluster connected to the session resource management server SRM includes two streaming servers, namely the streaming server 1 and the streaming server 2. After the request information of the file, obtain the network output bandwidth occupation and disk I/O speed of streaming server 1 and streaming server 2, and determine that the load of streaming server 1 is less than The load of the streaming server 2 will send the received request information to the streaming server 1.

Step 804: The streaming server directly sends the required segmented video files to the video playback terminal according to the request information.

In one embodiment of the present invention, after receiving the request information sent by the device for recording video-on-demand breakpoint information, the streaming server determines the required sliced video files according to the received request information, and directly downloads the required sliced video files Send it to the video playback terminal.

For example, after receiving the request information sent by the session resource management server SRM, the streaming server 1 determines the segmented video file 1 to be obtained by the mobile phone 1 sending the request information according to the request information, and directly sends the segmented video file 1 to the mobile phone 1 .

Step 805: The video playing terminal plays the corresponding video according to the received sliced video file.

In one embodiment of the present invention, after receiving the sliced video files sent by the streaming server, the video playback terminal plays the videos carried in the sliced video files in sequence.

For example, the mobile phone 1 receives the segmented video file user sent by the streaming server 1 or the streaming server 2, and plays the movie B according to the sequence of each segmented video file recorded in the index file M3U8.

Various embodiments provided by the present invention have at least the following beneficial effects:

1. In the embodiment of the present invention, since the video playback terminal needs to continuously send the request information for obtaining sliced video files when playing the on-demand video, when the video playback terminal does not send the request information for a period longer than the timeout period, it can be determined that the video playback terminal has stopped For the playback of video-on-demand, the playback progress of the video can be determined according to the request information sent by the video playback terminal last time, so as to form corresponding breakpoint information. In this way, the video playback terminal does not need to send the playback progress information of the video on demand separately, and the breakpoint information of the video on demand can be recorded through the request information sent by the video playback terminal, which saves the calculation consumed by the server when receiving and processing the playback progress information resources, thereby reducing the load on the server.

2. In the embodiment of the present invention, when the request information for obtaining sliced video files is sent to the streaming server, the load situation of each streaming server is first judged, and the request information is sent to the streaming server with the smallest load. The streaming server sends the required sliced video files to the video playback terminal, so that the load of each streaming server can be more balanced, so as to quickly send the required sliced video files to the video playback terminal, and ensure that the video playback terminal can play smoothly video.

3. In the embodiment of the present invention, the breakpoint information is stored in the breakpoint information database. After the user logs in on the same video playback terminal or a different video playback terminal, the video playback terminal can continue to play the video that the user did not have before according to the breakpoint information. After watching the finished video file, the user does not need to manually adjust the playback progress of the video after exiting the playback software and replacing the video playback terminal, which improves the user's experience in watching videos.

4. In the embodiment of the present invention, when storing the breakpoint information in the breakpoint information database, it is judged whether the breakpoint information database includes other video files corresponding to the same user ID and the same video file ID as the breakpoint information to be stored. Breakpoint information, if there is, overwrite other breakpoint information corresponding to the same user ID and the same video file ID with the breakpoint information to be stored, if not directly store the breakpoint information to be stored in the breakpoint In the information database, this ensures that the breakpoint information stored in the breakpoint information database is all up-to-date, ensuring the accuracy of recording the breakpoint information.
