Abstract

The invention discloses a multimedia encoding method and system, a recording method, an operation method and a media server. The multimedia encoding method comprises the following steps: step 101, collecting original multimedia data stream; step 102, configuring corresponding identification video data stream having the same frame rate for the original multimedia data stream, wherein the identification video data stream comprises multiple key frames, the multiple key frames comprise an identification program starting frame and an identification program ending frame, the identification program starting frame corresponds to a program starting frame, and the identification program ending frame corresponds to a program ending frame; and step 103, encoding the original multimedia data stream and the identification video data stream into program playing data together. According to the multimedia encoding method and system in the technical scheme provided by the invention, the identification video data stream having the same frame rate is configured on the technology of the original multimedia data stream to identify the starting point and the ending point of each program content, so that the media server can conveniently split the program contents precisely and provide instant playback service with higher quality for a client.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a multimedia encoding method and system, a method for recording on-demand programs, an operation method for instant programs and a media server. Background technique [0002] There are two main ways to watch back IPTV at present. One is instant playback (also known as: time shift), that is, when the viewer is watching a TV program, press the rewind button on the remote control to move forward at 2 times speed, 4 times speed, 8 times speed, 16 times speed, 32 times speed, etc. The timeline retrieves the program just played back. The other is on-demand look-back (usually, "look-back" refers to on-demand look-back), that is, the media server records the programs played in the past, and the audience can select the content to be played in the on-demand list (on-demand program ) to watch previously played programs on demand. [0003] There are some defects in the review services...
