A method and system for playing multimedia video on a network computer

Abstract

The invention discloses a network computer multimedia video playback method and system. The system includes a server, a network connection unit, a search unit, a cache unit, an instruction input unit, an audio and video synchronization unit, a decoding unit and a playback unit. The video data is divided into several segments, and under the condition that the data buffering within a certain continuous range calculated from the position of the currently decoded video data is guaranteed, the subsequent parts are intermittently cached, so the target video information needs to be jumped. , it can quickly determine the priority caching area, and can shorten the caching time of the video data at the jumping position, reduce the pressure on network data transmission, and can improve the response speed after video jumping and improve video viewing. At the same time, the present invention does not appear to have obvious audio and video synchronization after video jumping, and can ensure the smoothness of video playback during the jumping or frequent jumping process.

Description

technical field [0001] The invention belongs to the field of multimedia technology, and in particular relates to a method and system for playing multimedia video on a network computer. Background technique [0002] A network computer is a computer used on the network, but the traditional hard disk, floppy disk and other components are removed. It is a thin PC, and the program or storage on the network is provided by the server. In addition, other software needs to be downloaded from the network server, which saves frequent software upgrades and maintenance, and also reduces costs. [0003] In the prior art, when a network computer is playing multimedia video, because it does not have a large-capacity storage space, it mainly relies on the instant cache of the network to play the video. Therefore, when playing multimedia video, the stability of the network is required. Only in the case of high bit rate can the playback stability of the video after the jump be guaranteed. In ...

[0003] In the prior art, when a network computer is playing multimedia video, because it does not have a large-capacity storage space, it mainly relies on the instant cache of the network to play the video. Therefore, when playing multimedia video, the stability of the network is required. Only in the case of high bit rate can the playback stability of the video after the jump be guaranteed. In the case of an unstable network, after the video is jumped, the video will freeze and the playback will not be smooth; In the prior art, when a network computer is playing multimedia video, it mainly relies on the real-time cache of the network to play the video. Therefore, when playing multimedia video, it is greatly affected by the network conditions, and it is prone to audio and video misalignment. , especially after the video jump, because the time code cannot correspond in time, it is easy to cause short-term audio and video misalignment and out of synchronization
