Method and system for program source file preprocessing and on-demand broadcasting, and streaming media server

Abstract

A method, system and streaming media server for program source file preprocessing and on-demand, the main contents include: before the streaming media server provides on-demand services to user terminals, the operation control information of each program source file is extracted in advance, and the operation control information is stored. information, so that in the process of providing the on-demand service for the program source file to the user terminal, if an operation control request from the user terminal is simultaneously received, the received operation control request can be responded to according to the stored operation control information , there is no need to traverse to find the operation control information in the program source file in the content providing server, especially for the program source file in the ts format with a large amount of data, there is no need to traverse and search, which can reduce the resource consumption of the streaming media server in the process of providing on-demand services. , especially in the peak hours of the on-demand service, the resource occupancy of the streaming media server will be significantly reduced, thereby improving the performance of the streaming media server.

Description

technical field [0001] The invention relates to streaming media technology, in particular to a method, system and streaming media server for program source file preprocessing and on-demand broadcasting. Background technique [0002] With the increasing trend of triple-network integration of mobile network, Internet and cable TV network, the streaming media service of the mobile network needs to support Internet TV on demand through capacity expansion on the original mobile streaming media platform, that is, streaming media server (Streaming Server, SS) to provide user terminals with on-demand services for transport stream (transport stream, ts) format files. The ts format files refer to: a high-definition video format file that is mainly used for real-time transmission of video program services. Features It can be independently decoded from any segment of the video format file. [0003] Such as figure 1 As shown, it is a schematic structural diagram of the SS system in the...

AI Technical Summary

Problems solved by technology

[0010] When the streaming media server is currently used to provide on-demand services for ts format files, when the user terminal initiates an operation control request, the streaming media server must continuously send audio and video data packets to the user terminal to maintain the on-demand service. On the other hand, It is also necessary to find out operation control information such as key frames and PCR time stamps from the program source files in the content providing server. Since the data volume of the program source files of the ts format file is very large, the streaming server traverses the program source files and extracts from them When looking for operation control information, it needs to occupy a lot of system resources, resulting in a large system overhead of the streaming media server

[0011] To sum up, when the streaming media server currently provides on-demand services for ts format files, if it responds to the operation control request of the user terminal at the same time, the local resources of the streaming media server will be relatively large, especially during the peak hours of the on-demand service. The performance of the streaming server will be severely affected
