Abstract

The invention provides a self-alarming set top box, comprising a set top box main board, a power supply module, a front control plate, an AV terminal, a relay module and relay control circuit, wherein the power supply module is electrically connected with the set top box main board, and the front control plate is electrically connected with the set top box main board, and an input end of the AV terminal is electrically connected with a slave device, and a moving contact of the relay module is connected with the input end of the AV terminal and the set top box main board electrically. The self-alarming set top box of the invention can be used for fast and conveniently realizing AV signal input and switch of the slave device.

Description

technical field [0001] The invention specifically relates to a self-alarming set-top box. Background technique [0002] With the rapid development of digital television technology, set-top boxes have been widely used. According to different demodulation methods, set-top boxes can be divided into DVB-S (digital satellite integrated decoder), ABS-S / DTH (direct broadcast satellite digital integrated decoder), DTMB (terrestrial digital TV set-top box), DVB-C (cable digital TV set-top box). Since different program signals require different demodulation methods, if the user wants to watch programs with two different demodulation methods, two set-top boxes must be used to realize two different demodulation methods when the user only has one TV. There are usually two methods for program switching: the first one, when the TV has multiple AV signal input interfaces, the user needs to connect the signals of different set-top boxes to different AV interfaces of the TV through AV cable...
