DVB-S (digital video broadcasting-satellite) set top box compatible with various audio video signal interfaces and having standby mode

Abstract

The invention relates to a DVB-S (digital video broadcasting-satellite) set top box compatible with various audio video signal interfaces and having a standby mode. The set top box comprises a signal strength detecting device, a uniform signal interface device and a power management device, wherein the power management device is connected with the signal strength detecting device to confirm whether or not the set top box enters into the standby mode according to the signal strength detected by the signal strength detecting device, and the uniform signal interface device is compatible with the connection of audio-video signals in a DVI (digital visual interface) form, an HDMI (high-definition multimedia interface) form and a Displayport form. After the set top box is used, the audio-video signals in various forms can be received, the receiving and the processing of satellite digital television broadcast signals can be stopped when the satellite digital television broadcast signals are very bad, and the set top box enters into a standby status, so that the unnecessary power loss can be avoided.

Description

technical field [0001] The invention relates to the field of satellite TV reception, in particular to a DVB-S set-top box which is compatible with various audio and video signal interfaces and has a standby mode. Background technique [0002] Satellite broadcasting (satellite broadcasting) is a broadcasting method that uses broadcasting satellites to relay TV or sound broadcasting signals to the ground for the general public to receive directly. Since the United States successfully launched the world's first synchronous communication satellite "Synchronous II" in July 1963, satellite communication has developed rapidly. By the mid-1970s, countries began to launch experimental broadcasting satellites. Satellite broadcasting entered the practical stage in the 1980s. [0003] Digital Video Broadcasting DVB is a series of internationally recognized digital television open standards maintained by the "DVB Project". "DVB Project" is an industrial organization composed of more t...

Problems solved by technology

[0004] But, the receiver of existing satellite digital TV broadcasting signal DVB-S still must carry out the receiving and processing of satellite digital TV broadcasting signal when the signal is very poor, what play is meaningless audio and video content, has caused unnecessary power consumption, at the same time, the existing DVB-S receiver often only has an interface of one audio and video data format, and receives the audio and video data sent by the external audio and video data memory of a single format, and the compatibility is poor
