Abstract

The invention discloses a multi-format signal conversion device comprising a signal input module, a signal processing module and a signal output module, wherein the signal input module is used for collecting an external input signal, the signal processing module is connected with the signal input module and used for video signal format conversion processing of the external input signal, the signal output module is connected with the signal processing module and used for transmitting a signal which is processed by video signal format conversion to a signal transmission media. The multi- format signal conversion device supports multi-format signal input, and an analog video graphics array (VGA) signal, a composite video broadcast (CVBS) signal, a YPbPr signal, an S-video signal, a digital video interactive (DVI) signal and a high definition multimedia interface (HDMI) signal are compatible. Compatibility of signal input is good, and the multi- format signal conversion device and the display equipment are convenient for users to use.

Description

technical field [0001] The invention relates to the technical field of video output, in particular to a multi-format signal conversion device and a display device. Background technique [0002] At present, DVI (Digital Visual Interface, digital video interface) interface is mainly divided into two types: one is DVI-D interface, DVI-D interface can only receive digital DVI signals, and cannot receive any analog signals; the other is DVI-D interface I interface, DVI-I interface can receive digital DVI signal and analog VGA (Video Graphics Array, display graphics array) signal. In this way, the existing DVI interface can only be compatible with digital DVI signals and analog VGA signals, and its signal input compatibility is relatively poor. In the case of a wide variety of signal sources, different signal interfaces need to be used to collect different signal sources, resulting in signal The diversification of collection systems also brings great inconvenience to users. Con...
