Problems solved by technology

In addition, home audio-visual / entertainment equipment such as game consoles, digital cameras, digital video cameras, wireless FM receivers or satellite TV receivers mostly use the same audio / video input interface, which makes the limited audio / video input interface of existing home TV sets insufficient. To meet the needs of users, the use of different audio-visual equipment requires re-plugging audio / video cables
There are also some home TVs whose audio / video input interface is located on the rear side of the TV. Users need to move the TV repeatedly to re-plug the audio / video cable, which is very inconvenient, and the audio / video input interface may contact due to frequent plugging and unplugging. Bad, reduces the quality of the audio / video input

Abstract

The invention provides a signal switch device, comprising at least one audio / video input interface, a control unit, an audio / video output interface and a power unit. At least one audio / video input interface respectively receives at least one group of audio / video signal, and the control unit is respectively connected with at least one audio / video input interface and the audio / video output interface. One audio / video input interface from the at least one audio / video input interface is chosen and the audio / video signal from the chosen audio / video input interface is output through the audio / video output interface; the power unit supplies power for the control unit and the audio / video output interface respectively; the invention also provides a signal switch system which is provided with the signal switch device and a top box of the digital television; the signal switch device combines the top box of the digital television and easily switches among a plurality of audio and video equipments, thus saving the trouble of manually inserting the audio / video input interface and ensuring stable audio / video input quality.

Description

technical field [0001] The invention relates to the field of audio and video playback, in particular to a signal switching device and system. Background technique [0002] Existing household television generally only has one to two groups of audio / video input interfaces, which are used to connect CD players such as VCD and DVD. Along with the digital cable TV, the digital TV set-top box has become a necessary TV signal receiving device for home use. Digital TV set-top boxes generally use the same audio / video input interface as VCD, DVD and other optical disc players. In addition, home audio-visual / entertainment equipment such as game consoles, digital cameras, digital video cameras, wireless FM receivers or satellite TV receivers mostly use the same audio / video input interface, which makes the limited audio / video input interface of existing home TV sets insufficient. To meet the needs of users, the use of different audio-visual equipment requires re-plugging the audio / vide...
