Abstract

The invention discloses a digital television audio / video data recording and playback method solving the location problem according to programs during the recording audio / video data playback. The method comprises: recording the audio / video data in a ts stream to a storage medium; simultaneously, real-timely detecting and parsing si data, recording electric program epg information of a channel in a recording process; storing the epg information into an epg information list of the storage medium; storing a corresponding relation of the event information in the epg information and said recorded audio / video data play position in epg information list; locating the play time of the audio / video data to play according to the epg information list. The invention also provides a corresponding system. Because the technique scheme of the invention records the corresponding epg information as well as the audio / video data, and preserves the epg information as a list, when the users play back the audio / video data, the invention can locatedly play according to the epg information, and facilities the user choice.

Description

technical field [0001] The invention relates to the technical field of digital TV audio and video playback, in particular to a method and system for recording and playback of digital TV audio and video data.
