Abstract

The invention provides a three-into-one-mode-based set-top box and a realization method. The set-top box comprises a control chip processor, a demodulator connected to the control chip processor, and a tuning device connected to the demodulator. The control chip processor is connected to a tuner by a TS steam switch; the tuner is used for receiving terrestrial television, satellite television and cable television signals. The control chip processor is also connected with a video encoder, an audio D/A converter and an infrared receiver. Compatibility with satellite, ground and wired tuning modes is realized by using one tuning device and receiving of different modes is realized based control among control chip processor, the demodulator, and the tuning device, so that different signal receiving demands of users can be satisfied; the set-top box can be used conveniently; the using cost is lowered; the beautiful and space-saving effects as well as saving and environment protection effects are realized.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a set-top box based on a three-in-one mode and an implementation method thereof. Background technique [0002] A Digital Video Converter Box (Set Top Box, referred to as STB), commonly known as a set-top box or set-top box, is a device that connects a TV to an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. Signals can come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. [0003] At present, most of the existing set-top boxes are of a single mode, and very few are compatible with ground and satellite, but cannot support satellite, ground, and cable modes at the same time, so that it cannot meet the different needs of users for receiving signals and ensure different environments. It can be received under any circumstances, which makes it inconvenient to use and increases the...
