Abstract

The present invention discloses an HTTP live streaming (HLS) client-based network stream downloading terminal and optimization method. Through adoption of the system and method, network speed fluctuation falls into the following categories: network speed slow rise, network speed slow fall, network speed soar, and network speed plunge; the network speed change type is identified by comparing instant speed information with a bandwidth of a current audio video stream or comparing the instant speed information with average speed information; a corresponding network stream is selected according to the network speed change type; and finally the network speed of the substantial and sudden change type is optimized. The user experience is improved.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to an HLS client-based network stream download terminal and an optimization method. Background technique [0002] HLS is an HTTP-based streaming media transmission protocol implemented by Apple, which can realize live broadcast and on-demand streaming media, and provide audio and video live broadcast and on-demand solutions for mobile devices. [0003] The HLS protocol converts the media data stream on the server side into different quality, continuous, short-duration media files (MPEG-TS format, generally each small file can be played for 8 seconds, called fragmentation), and the client The end continuously downloads and plays these fragments. [0004] Usually, for the same program, the server provides multiple audio and video streams with different qualities (each quality audio and video stream contains a set of slices, corresponding to a bit rate), and the configuration file in ...
