Problems solved by technology

[0010] Therefore, if the user tries to change the channel during the viewing process, receiving the broadcast signal from the desired channel requires the process of "program specific information PID screening" and "section (section) screening" as in the above-mentioned initial channel screening process, It takes 2 to 3 seconds for the process of "program-specific information PID screening" and "section screening", so when switching channels, there is a problem that the broadcast signal that the user switches channels cannot be received quickly

Abstract

This invention relates to the method and device for receiving and processing broadcast signal, which contains displaying decoded broadcast signal received from current channel, sieving and storing grouped identifying information of other channel, decoding and displaying broadcast signal of switched channel by utilizing stored grouped identifying information of corresponded channel when there is channel switching request.

Description

Technical field [0001] The present invention relates to a broadcast signal receiving method and device, in particular to a channel switching method and device for quickly responding to user channel switching requirements. Background technique [0002] Digital broadcasting is being normalized in recent years. Digital broadcasting is very different from the existing analog broadcasting. Digital broadcasting is a mode in which video and audio signals are transformed into digital signals, and the digital signals are compressed and transmitted according to a specific transmission mode. At present, countries around the world determine the digital broadcasting specifications suitable for their own countries according to their actual conditions, which is the current development trend. [0003] Current digital broadcasting usually chooses the mode of compressing video and audio signals and packetizing the compressed signals before transmitting them. Usually, the video signal is com...
