Abstract

The invention discloses a method and system for segmenting internet protocol television (IPTV) stream media file virtually. The method for segmenting internet protocol television stream media file virtually comprises the steps of: arranging a preprocessor in the IPTV system, and carrying out the followings steps of: segmenting a received media flow or media file to be segmented to obtain a plurality of segmented files; inserting key frames or identifications used for indexing into the segmented files respectively; combining the segmented files inserted with the key frame or identifications so that a virtual segmented media file is formed and stored into a file system; establishing an index file of the virtual segmented media file including the information of the key frames or identifications; and according to the playing request of a client, reading the segmented files of the virtual segmented media file from the file system by utilizing the index file, and transmitting the segmented files to the client. By using the method and system for segmenting PTV stream media file virtually, the problem of media file storage of hyper text transport protocol (HTTP) media service is solved, and a technical obstacle for three screen fusion is really removed.

Description

technical field [0001] The present invention relates to an interactive network television system, that is, an IPTV system, in particular to a method for realizing virtual segmentation of streaming media files and a related system. Background technique [0002] As a video media service business, IPTV has achieved considerable development. With the advent of the 3G era, the market's demand for three-screen integration is becoming more and more intense. It will allow IPTV users and business markets to grow faster, and it will be a breakthrough for mobile streaming media, especially IPTV, to break through the current development bottleneck. Nice try. [0003] The so-called three-screen refers to the computer screen, TV screen and mobile phone screen. The current integration of the three screens is to realize the interconnection and intercommunication of content between the mobile phone screen, computer screen and TV screen from the perspective of the terminal. Of course, this ...
