Abstract

The invention provides a method for digital televisions to acquire audio and video files, belonging to the field of image transmission. The method comprises the following steps: program special information / service information PSI / SI is received from a transport stream TS broadcasted by a digital television server; a plurality of audio and video file descriptors are resolved from the PSI / SI information; according to the audio and video file descriptors, audio and video files are obtained from the TS stream. The method has the advantages that, the digital television server loads the audio and video files and the PSI / SI information with corresponding descriptors of audio and video files to the TS stream for broadcasting, therefore a digital television receiving terminal can resolve audio and video files from the received TS stream according to the descriptors corresponding to the audio and video files; the scarcity of audio and video file resources is solved, and the recreation experience of users for digital television broadcasting system is enriched.

Description

technical field [0001] The invention belongs to the field of image transmission, and in particular relates to a method, a system and a terminal for digital television to obtain audio and video files. Background technique [0002] As the digital video broadcasting (Digital Video Broadcasting, DVB) system is widely used, the program services provided by the DVB system are becoming more and more abundant. [0003] Currently, when a user uses a digital television receiving terminal to play audio and video files, the audio and video files need to be stored in the digital television receiving terminal first. At present, some digital TV receiving terminals record audio and video data in real time through PVR to make audio and video files. Due to the limitation of storage space, a digital TV receiving terminal may only be able to store a limited number of audio and video files. Therefore, when a user uses a digital TV receiving terminal to play audio and video files, the problem o...
