Network video data buffer control method and system based on mobile terminal

Abstract

The invention discloses a network video data buffer control method and system based on a mobile terminal. Whether the difference value that a circular cache buffer maximum position exceeds a current reading position is larger than or equal to a first threshold value is judged, and then whether rest network video data need to be downloaded is controlled. According to the scheme, the problem that buffer data can be covered easily because video data have a local random access characteristic and the serial problems like network reconnection and data retransmission due to covering of the buffer data can be solved, meanwhile, the phenomenon that an audio / video is unsmooth because of low network speeds is improved, network download flow can be saved, and continuous playing of the network video can be achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a mobile terminal-based network video data buffering control method and system. Background technique [0002] At present, since the downloading speed of network video data of mobile terminals is increasing substantially, people gradually begin to watch videos through mobile terminals. When users use mobile terminals to watch videos online, they need to download the video resources on the network server to the circular cache of the mobile terminal first, and start watching after the video files have been transferred to the circular cache to a certain amount. [0003] Video files are mainly composed of data blocks such as index, audio, and video, and are stored in blocks. When playing video, audio and video are required to be output synchronously. Although the storage of audio data and video data are linear, audio data blocks and video data The storage of da...

Problems solved by technology

If the video file is played to point B, the original video data or audio data stored at point A needs to be used, because the video file stored at point A has been overwritten, so the mobile terminal needs to re-download the video stored at point A data or audio data, this will cause the mobile terminal to stop playing the video file, and it will not continue to play until the video data or audio data stored at the original point A is downloaded, so that the video playback becomes discontinuous. Therefore, the existing video buffer The method needs to download the video file that has been downloaded and overwritten multiple times, which not only wastes the network download traffic, but also makes the user unable to watch the video file normally due to the intermittent playback effect
