Method, device and system for playing streaming media contents

Abstract

The invention discloses a method for playing streaming media contents. A streaming media player receives streaming media data corresponding to the streaming media contents to be played, wherein the streaming media data is the streaming media data in a new streaming media format. The data in the new streaming media format structurally comprises a head, an index and one or more new streaming media packets sequentially, wherein the head is used for describing the media information of a file; the index is used for storing an index table of the position of video key frames; elements in the index are stored from a smaller time stamp to a larger time stamp; the new streaming media packets are used for storing a video frame or one or more audio frames respectively; the new streaming media packets are stored from the smaller time stamp to the larger time stamp; the streaming media data in the new streaming media format is buffered and analyzed; and when the total traffic of the received streaming media data is equal to a buffer threshold of the streaming media data, the streaming media contents corresponding to the streaming media data are played.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for playing streaming media content. Background technique [0002] Streaming media is a media format that is transmitted over the network in a streaming manner. The method of playing streaming media content in the prior art is: the data source is provided by the content source; the content preparation module performs content fragmentation and generates metadata according to the content input of the data source and related environmental information, and publishes the content fragmentation and metadata to Streaming media server; the streaming media player obtains the web page address (Uniform / Universal Resource Locator, URL) of the metadata, and requests the metadata from the streaming media server, wherein the metadata is used to describe fragmentation information; the streaming media server will The metadata is sent to the streaming media player; the...

AI Technical Summary

Problems solved by technology

[0003] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems: to play streaming media content in a fragmented manner, it is necessary to add a content preparation module for generating metadata and fragments, and the implementation cost is relatively high; Because different bandwidths and different streaming media players have different requirements for the size of content fragments, it is difficult to control the size of content fragments, which increases the complexity of the streaming media content playback system; the generation of content fragments increases the number of streaming media content The management of the playback system is difficult, and in the case of many program sources, a lot of content fragments will be generated, which will easily cause the performance of the playback system of streaming media content to decrease
