Abstract

The invention discloses a digital television channel fast switching method and device and a terminal. The method comprises the following steps: determining a to-be-switched target channel according to a received channel switching instruction; obtaining a pre-stored M3U8 file corresponding to the target channel through a network, and obtaining and playing a content fragment corresponding to the current time in the M3U8 file; locking a corresponding frequency point according to the target channel, and obtaining a digital transport stream corresponding to the frequency point; analyzing an audio and video data stream from the digital transport stream; and after playing the content fragments for a period of time, switching from the network channel to the broadcast and television channel, and playing the audio and video data stream at the corresponding time point. According to the method and the device, the channel switching speed is improved by adopting a mode of combining the network channel and the broadcasting and television channel, the network data of the target channel at the current time is firstly played during channel switching, the broadcasting and television channel is switched to after the network data is played, and the corresponding digital transport stream is played, so that lag and pause feeling during channel switching are avoided, and the purpose of rapid channel switching is achieved.

Description

technical field [0001] The present application relates to the technical field of digital television, in particular to a method, device and terminal for quickly switching digital television channels. Background technique [0002] With the development of the digital TV industry, more and more programs can be watched on TV, and it becomes more and more difficult for users to quickly switch channels. [0003] At present, in the field of digital TV, the most widely used is the DVB+OTT product with two-way function, which is characterized by DVB (Digital Video Broadcasting, digital video broadcasting) Two-way data transmission network cable, EOC (Ethernet Over Cable, Ethernet coaxial transmission technology) or CM (Cable Modem, user terminal equipment), and digital signals are transmitted through TS (Transport Stream, transport stream), one program The production needs to go through: tuner frequency locking, demux analysis (filtering PAT (Program Association Table, program associ...
