Method and system for quickly starting playing of network multimedia files

Abstract

The invention discloses a method and system for quickly starting playing of network multimedia files. The method comprises the steps that multimedia file metadata and key media content of server sides are pre-stored in client sides, the pre-stored multimedia file metadata are indexed, the multimedia files which are requested to play by a user are obtained, and the content steps or modules which are requested to play by a user are obtained, and the pre-stored multimedia file metadata and key media content between the server sides in the client sides are updated and synchronized. The system comprises a module used for pre-storing the multimedia file metadata and the key media content of the server sides to the client sides, a module for indexing the pre-stored multimedia file metadata and obtaining the multimedia files which are requested to play by the user, and a module for updating and synchronizing the pre-stored multimedia file metadata and the key media content between the client sides in the server side. Through the method and the system, the user can enable the network multimedia files to be played and started more quickly, play quality is guaranteed, low re-cache rate is maintained, and using experience of the user is further improved.

Description

technical field [0001] The invention relates to a multimedia transmission method and system, in particular to a method and system for quickly starting and playing network multimedia files. Background technique [0002] Video Streaming refers to the transmission of video data, for example, that can be processed as a steady and continuous stream over a network. Because of streaming, a client browser or plug-in can display multimedia data before the entire file has been transferred. The quality of service evaluation of video playback technology using video streaming usually involves media playback start time (start-to-play), rebuffering ratio (rebuffering ratio) and video quality (video quality), which are mutually restrictive ,Influence each other. Video streaming usually also involves adaptive streaming technology (Adaptive Streaming), which adaptively adjusts the quality of the transmitted video according to the changes in the network conditions of the client and server to...

AI Technical Summary

Problems solved by technology

In the case of high latency or other unfavorable conditions such as very low bandwidth, high packet loss rate, or small maximum transmission unit (MTU, full name Maximum Transmission Unit) constraints, it takes a long time to obtain media metadata from the server Time, which is a big additional overhead for the start-to-play time (start-to-play, which refers to the period from the time the user chooses to play to the time when the media actually starts playing)

Excessively long start playback time will bring users a poor experience. The existing methods achieve the purpose of fast start playback by sacrificing other video streaming playback performance, but the multimedia quality will not be guaranteed or require high recaching rate of
