Method and system supporting simultaneous broadcasting and recording of program sources of different modes

Abstract

The invention discloses a method and a system supporting simultaneous broadcasting and recording of program sources of different modes. The method comprises the following steps of: simultaneously receiving a first mode program source and a second mode program source through a set-top box; after demodulating and decoding the first mode program source, obtaining a first transport stream through demultiplexing; after demodulating and decoding the second mode program source, obtaining a second transport stream through demultiplexing; decoding the first transport stream to obtain first audio-video data, outputting the first audio-video data to a first audio-video player; and storing the second transport stream in a hard disk. The same set-top box can simultaneously accept two paths of program sources of different modes, and realizes recording the program in the program source of another mode while broadcasting the program in the program source of one mode, thus, the user requirement of recording the program of the program source of different mode while watching the program is satisfied well, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of program reception, in particular to a method and system for supporting simultaneous playback and recording of program sources in different modes. Background technique [0002] Now more and more users use set-top boxes. With the rapid development of technology, and in order to meet the requirements of users for functions and usage, PVR set-top boxes have appeared, which can watch the TV programs we want to watch without having to keep in sync with the broadcasting time of TV stations. Through an external hard disk or other storage device, the TV program to be watched can be stored in the storage device, and the program can be watched at any time, and the function of fast forward and fast rewind can be provided. However, at present, a set-top box cannot simultaneously receive program sources of two different modes, for example, a set-top box cannot receive satellite programs while receiving cable programs. ...

AI Technical Summary

Problems solved by technology

But at present, it is still impossible to receive two different modes of program sources at the same time through a set-top box. For example, the set-top box cannot receive satellite programs while receiving cable programs.

Moreover, the PVR set-top boxes currently on the market meet the requirements of watching and recording. The boxes are all programs at the same frequency point. There is no way to meet the requirements of recording and watching programs in different receiving modes. The recording function and receiving function are limited.
