Method and system for playing programs

Abstract

The invention discloses a method and system for playing programs. The method comprises the steps of: detecting whether the current program is coming into an end by a video server, if so, sending an informing message to a conversation management server before the playing of the current program is ended, informing the conversation management server that the current program is coming to an end, and requesting program information of the next program; after receiving the informing message by the conversation management server, finding the program information of the next program, sending a reply message to the video server, and sending the program information of the next program to the video server; and after receiving the reply message by the video server and when the playing of the current program is ended, pushing a video stream of the next program to a digital television receiving terminal. The invention has the advantages of solving the problem that display dimness or transient black screen exists in the digital television receiving terminal when the programs are automatically switched in the prior art, realizing seamless switching, and simplifying the program switching process because the conversation process step is simple.

Description

technical field [0001] The invention relates to the technical field of playing digital television programs, in particular to a method and system for playing programs. Background technique [0002] In the existing digital TV technical field, when a user orders a video program recorded on a video server through a digital TV receiving terminal such as a set-top box, if it is necessary to directly switch to the next program for playback after the current program is played, the current There are technically two solutions, the first, such as figure 1 As shown, when the current program is played, the session management server searches for the next program and notifies the video server to play it. The steps are as follows: the set-top box sends a program playback request to the session management service, which includes the channel information and time-shift time information of the program; session management The server finds the program name to be played according to the channel i...

Problems solved by technology

[0005] Compared with prior art 1, the process of this solution is simpler, and it can switch to the next program for playback more quickly. However, it also has a relatively large disadvantage: when multiple video servers simultaneously record the same program (usually a popular program) ), some video servers may fail to record or the recording effect is not good

When a user requests the program, the session management server may dispatch the video server that fails to record or the recording effect is not good to provide the user with on-demand service. However, for the video server, if the recorded program fails, it will switch between programs Skip the program that failed to record and play the next one directly; if the recorded program is not good (for example: blurred screen or mosaic), the video server will continue to push the stream to the set-top box, which will affect the viewing effect of the program.

[0006] It can be seen that the two solutions of the prior art cannot realize the function of directly switching broadcast programs quickly and effectively.
