Abstract

The present invention relates to a set top box for receiving DVB-C and DTMB (Digital Television Terrestrial Multimedia Broadcasting) dual-way signals at the same time. The set top box comprises: a main chip configured to process and calculate data and control work of peripheral parts of the system; a tuning unit configured to tune radio and television signals; a demodulator configured to demodulate signals; and a storage configured to store program audio-video data. The present invention further discloses a method for receiving DVB-C and DTMB dual-way signals at the same time. The set top boxsystem and method for receiving DVB-C and DTMB dual-way signals at the same time can play programs in the DVB-C and DTMB signals sources on the same television at the same time and can flexibly switchprograms in different signals so as to reduce the economic cost and enhance use convenience and practicability.

Description

technical field [0001] The invention relates to the technical field of TV set-top boxes, in particular to a set-top box system and method for simultaneously receiving DVB-C and DTMB dual-channel signals. Background technique [0002] With the rapid development of high-definition digital TV set-top boxes, people's demand for set-top boxes is not limited to only supporting DVB-C (Digital Video Broadcasting on Cable) signals or other broadcast TV signals. Set-top boxes that receive two or more different signals, for example, can process both DVB-C signals and DTMB (Digital Television Terrestrial Multimedia Broadcasting, frame structure, channel coding and modulation) signals. Because the set-top box that can process DVB-C and DTMB signals at the same time can work normally on DVB-C and DTMB digital TV broadcasting systems, it effectively solves the problem that a digital TV set-top box cannot play DVB-C and DTMB programs at the same time. [0003] Current digital TV set-top bo...
