Abstract

The invention discloses a set-top box for supporting multiple television terminals, which comprises a full-band high-frequency head, a demodulator module, a plurality of demultiplexing/multiplexing modules and an audio/video data conversion module. The full-band high-frequency head is used for converting locked antenna radio-frequency signals in a plurality of frequency points into medium-frequency signals and transmitting the medium-frequency signals to the demodulator module, the demodulator module is used for demodulating program transmission streams of a plurality of channels from the medium-frequency signals and respectively transmitting the program transmission streams to the demultiplexing/multiplexing modules, and the demultiplexing/multiplexing modules are used for analyzing audio/video data in the programs of the channels from the program transmission streams according to the program demanded by a user; and the audio/video data conversion module is used for converting the audio/video data in the programs of the channels into signals capable of being identified by television terminals and outputting the signals to the television terminals. The invention also discloses a method for realizing support of a plurality of television terminals through the set-top box. The set-top box can support multiple television terminals so that users can simultaneously watch television programs, the optional programs of each television are not limited to one frequency point, the scope of selection of the television terminals can be broadened, and the user experience can be enhanced.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a set-top box and method for supporting multiple television terminals. Background technique [0002] At present, TV signals have entered the digital era in an all-round way. Traditional analog TV signals have been gradually turned off or only a few programs are reserved. However, traditional TV terminals can only receive analog TV signals. To enable traditional TV terminals to receive For digital TV signals, a set-top box must still be configured to decode and convert digital TV signals into analog signals that can be received by TV terminals. [0003] With the improvement of people's living standards, it has become more common for a family to have two or more television sets. Because there is only one set-top box and one TV line, digital TV programs can only be watched on one TV set, and other TVs can only watch analog TV programs. If other TVs also need to watch digital TV p...
