Dumb Dvb C T Module Assembly
Along with the rapid development of high-definition Digital TV set-top boxes, people’s demand for set-top box has not only stayed in the case that it can only support the DVB-C (cable Digital Video Broadcasting) signals or other single or multiplex Broadcasting and TV signal input set-top boxes, also includes a set-top box that can receive two or more different signals at the same time, such as it can not only deal with DVB-C signal at the same time, but also can handle DTMB (Digital Television Terrestrial Multimedia Broadcasting, Digital television terrestrial broadcast transmission system frame structure, channel coding and modulation) signals. Because the set-top box that can handle dvb-c and DTMB signals simultaneously, it can work normally on dvb-c and DTMB digital TV broadcasting systems, effectively solving the problem that dvb-c and DTMB programs cannot be played simultaneously in a digital TV set-top box.

Nowadays, digital TV set-top boxes generally only support single input or multiple input of a certain signal source, such as dvb-c,DTMB, dvb-t (digital terrestrial television broadcasting), dvb-s (digital satellite television broadcasting) and so on. Such a box would not be able to broadcast programs from DTMB and dvb-c broadcast signals at the same time, so it would be limited and not very flexible.
China Dvb C Module Assembly
Existing digital TV set-top boxes can only broadcast programs from one broadcast signal. Such a set-top box can basically meet the needs of the public, but this has its limitations. Because in some family, there may be existing cable television broadcast signal as well as DTMB, radio and television signals, if they want to see the DVB-C program, while wanting to see DTMB program again at the same time, they can only open respectively two corresponding signal set-top boxes to watch programs, this greatly increasing the economic costs, and it is not convenient to use.
Technical realization elements: the purpose of the utility model is to provide a dvb-c and dtb-c dual-channel signal set-top box and a method to receive dvb-c and dtb-c signals at the same time in order to reduce the economic cost and enhance the convenience and practicability of use.

A dvb-c and DTMB dual-channel signal set-top box, including: main chip, responsible for processing and computing data, and control system peripheral components work, the main chip internal integration to understand the multiplexing module, audio decoder and video decoder, wherein, the demultiplexing module is responsible for demultiplexing mpeg-2 transmission stream into ES; The audio decoder is responsible for encoding digital audio signals into analog audio signals. Video decoder is responsible for encoding digital video data into analog TV signals;
The tuner includes the first tuner and the second tuner. The first tuner is responsible for processing the received dvb-c signal and converting the dvb-c signal into the required if signal after frequency selection, amplification and frequency conversion. The second tuner processes the received DTMB signal and converts it into a useful if signal after frequency selection, amplification, and conversion.
