Embodiment Construction

[0062] The technical solution of the present invention will be further elaborated below in conjunction with the drawings and specific embodiments.

[0063] The present invention preprocesses the original media file on the streaming media server, and obtains the index information corresponding to the original media file through analysis, including: the total duration of the original media file, the total number of data packets of the original media file, the size of each data packet, The header size of the original media file, the average bit rate, the total number of memory management units, the starting offset position of the media data per second in the original media file, whether there is a key frame in the media data per second, every second The number of memory management units included, the number of data packets included per second, and so on. The index information obtained by the analysis is stored in a data structure and written into the tail or head of the original medi...

Abstract

The invention discloses a media file demanding method which comprises the steps as follows: when receiving a media-on-demand request from a client, a server provides the client with index information in a self-defined (customized) media file; when receiving a playing-process request from the client, the server searches for media data starting offset position corresponding to the request time in the index information according to the request time in the playing-process request; the server reads the media data corresponding to the request time in the self-defined (customized) media file and provides the media data to the client. The invention also discloses a media file demanding system and equipment, which divide the original media file into fragments according to the time by means of the index information obtained by analyzing the original media file so as to cause the user to make request for data according to the time when watching a program and moving a broadcast process scroll bar, thereby quickly obtaining the media data corresponding to the time of the position of the broadcast process scroll bar and bringing more use experiences for the user.

Description

Technical field [0001] The present invention relates to video and audio on-demand technologies in the Internet, and in particular to a method, system and equipment for on-demand media files. Background technique [0002] With the development of social economy and technological progress, users’ demands for data and image services, especially multimedia services are increasing day by day. The development of new types of bandwidth services has become an important goal of the information industry. Video on Demand (VOD) is broadband One of the most representative typical applications in the business. VOD allows users to freely order media programs in a streaming media server on a computer or TV according to their own interests. The initiative is completely in the hands of users, which fundamentally changes the lack of passive viewing of programs by users. [0003] Traditional VOD uses client / server (C / S) connection mode to provide on-demand services. Due to input / output (I / O) bottlene...
