Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The method of broadcast program of the present invention may further comprise the steps:
Whether video server detects current program and closes to an end, if, then finishing the forward direction session management server and send a notification message in current playing programs, the current program of announcement session management server closes to an end, and asks the programme information of next program;
After session management server receives described notification message, search the programme information of next program, transmit a reply message, the programme information of next program is sent to video server to video server;
After video server is received described answer message, when current playing programs finishes, to the video flowing of the next program of receiving terminal for digital television plug-flow.
Below to play time shift program with the user by set-top box be that an embodiment is described in detail, as shown in Figure 3.After the user sent the instruction of a certain program of program request to set-top box, set-top box generated the playing programs request, wherein carried the pertinent program information of this program, comprised channel information and time shift temporal information, then, sent the playing programs request to session management server.
In embodiments of the present invention, store the various video programs of playing for the user such as time shift program, direct playing and playback program and request program on the video server in advance.Simultaneously, the time started of all video frequency programs, concluding time, channel identifier, whether record that success, corresponding program information such as video server all are stored in the database in advance, session management server can be visited this database, search corresponding programme information, after receiving the playing programs request that set-top box sends, according to programme information, search corresponding program names and shift time, select suitable video server, send described program names and program start time is carried out video request to it.For time shift program and direct playing and playback program, program start time can be called shift time again.
After video server is received described video request, confirm that it stores this time shift program, return confirmation to session management server, session management server is transmitted described confirmation again to set-top box, simultaneously, video server is opened the file of this time shift program, to the video flowing of this program of set-top box plug-flow.At last, set-top box receives and plays this video flowing.
Video server detects the play position of this program in real time in the process of set-top box plug-flow, judges whether this program is about to play finish, and particularly, has two kinds of detection methods in embodiments of the present invention:
Method 1: video server at first needs program stream data is read in buffering area when plug-flow, therefore the time that runs through program stream data always wants Zao to program stream to the intact time of set-top box plug-flow than video server, therefore, can whether read to finish according to program stream data and judge whether current program is about to play finish, if read and finish, then be judged as and close to an end.The time when finishing of program stream data can being read to the time that session management server sends a notification message, is asked the programme information of next program as video server.But want Zao how long also uncertain owing to run through specifically intact than the plug-flow time of time of program stream data, this need judge according to blocks of files size, playback rate, current played file block size, buffering area number (buffer size is identical with the blocks of files size that reads at every turn) that video server reads at every turn.For example read blocks of files size for B (MB of unit), playback rate are that the size of r (MB/S of unit), current file piece is S (MB of unit), buffering area number m (generally having two) at every turn, run through so than finishing Zao ((m-1) * B+S%B)/r) around.Therefore, this method realizes that simple only need be when file runs through sending a notification message to session management server get final product, and still not configurable, flexibility is not enough, and can not determine how long send a notification message in advance.
Method 2: video server need be analyzed the program of playing when broadcast program, obtain the information such as code check, duration, coded system of program, time threshold values of video server configuration, whether the residue playing duration (being that total program duration deducts the side-play amount of having play) that regularly detects current program then is less than or equal to this time threshold values, if, then be judged as and close to an end, send a notification message, ask the programme information of next program to session management server.This method need realize a timer, and whether regular going detects Rule of judgment satisfies, and is complicated a little in the realization, but it is configurable, more flexible, and how long to send a notification message in advance be controlled.For example be set to 1 minute, promptly just can be judged as finishing only to remain 1 minute from current playing programs when is to deny as if then being judged as greater than 1 minute.Concrete time threshold values can be provided with according to actual conditions.
When being judged as when being, video server finishes the forward direction session management server in current playing programs and sends a notification message, and this notification message is used for the current program of announcement session management server and closes to an end, and next program is play in request.In embodiments of the present invention, this notification message is that the Announce message of standard is expanded, and increases the program_name field, forms the NAnnounce request message, and it can adopt form as follows, and this form is a kind of example:
