RTSP based stream media playing method and system thereof on mobile terminal

Abstract

The invention discloses a RTSP based stream media playing method of a mobile terminal, which comprises the steps that: a, a client sends supported media types to a server; b, the server finds out database server to find out a media data set matched with the media types from a media database; c, media data the code rate of which is smaller than or equal to and is closest to the downlink rate of network bandwidth is selected from the media data set; and d, the server sends media data to the client. When the code rate of the media data is smaller than or equal to and is closest to the downlink rate of the network bandwidth, the condition of pause buffering can not appear in the playing process so as to meet the requirement of a user on smooth media playing. The media data with best playing effect and optimal definition is selected on the premise of playing smoothly by the user so as to meet the requirement of the user on playing high-definition media, so the invention can meet the requirement of selecting high-definition media to be played on the premise of playing the media smoothly.

Description

technical field [0001] The present invention relates to the technical field of wireless network application, and more specifically, relates to a method and system for playing streaming media by a mobile terminal based on RTSP. Background technique [0002] It is quite common for mobile terminals to implement streaming media, generally based on real-time streaming protocol (RTSP), P2P, RTP and other protocols, among which RTSP is an application-level protocol that controls the transmission of real-time data. RTSP provides an extensible framework that makes it possible to control and on-demand real-time data, such as audio and video. The purpose of this protocol is to control multiple data transmission connections, provide a way for selecting a transmission channel, such as UDP, multicast UDP and TCP, and provide a method for selecting a transmission mechanism based on RTP. RTSP is a communication mode based on C / S architecture, and its interaction mode is as follows: that is...

AI Technical Summary

Problems solved by technology

If the user's network bandwidth traffic is small, and the streaming media system finds a playback format with low compression rate (such as AVI, etc.) from the server, the client will not be smooth when playing the media, and buffering and pauses often occur; If the user's network bandwidth traffic is large, and the streaming media system finds a playback format with a high compression rate (such as 3GP, etc.) from the server, although the playback format has a small capacity, the image is not clear enough, so the user cannot Enjoy clear playback

Therefore, the existing technology does not take into account the actual situation of the user's network bandwidth, resulting in poor actual playback effect of the client during the playback process.
