Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0017] Such as figure 1 As shown, a HDMI interface multiplex transmission device for SCART and HDMI signals, which includes a signal switching circuit, the signal switching circuit is set between the processor and the HDMI interface, and the HDMI interface is respectively connected to the SCART signal through the connecting line. The device is connected to the HDMI signal generating device, and the processor detects the level area according to the high and low levels generated by the two input signals, so that the signal switching circuit switches the HDMI signal and the SCART signal to the corresponding signal input interface of the processor .

[0018] The present invention can save the SCART interface, and realize the multiplexing interface transmission of HDMI and SCART signals through the HDMI interfa...

Abstract

The present invention discloses an apparatus for transmitting SCART and HDMI signals by multiplexing an HDMI interface. The apparatus comprises a signal switching circuit, wherein the signal switching circuit is arranged between a processor and an HDMI interface; the HDMI interface is connected to an SCART signal generating device and an HDMI signal generating device separately via connecting lines; the processor detects high and low electrical levels generated according to two input signals at an electrical level region, so as to enable the signal switching circuit to switch an HDMI signal and an SCART signal to a corresponding signal input interface of the processor. The apparatus disclosed by the present invention enables electric products to be lighter and thinner in the case that transmission of SCART and HDMI signals is achieved.

Description

technical field [0001] The invention relates to the field of electronic equipment supporting HDMI and SCART signal decoding, in particular to a device for multiplexing and transmitting SCART and HDMI signals through an HDMI interface. Background technique [0002] With the thinning and thinning of electronic products, the size of some terminal interfaces is too large. For example, the SCART interface of products facing Europe is a standard terminal, but its size is too large, which puts forward higher requirements for the structure and terminal design. This article provides A design scheme using an HDMI interface instead of a SCART interface to realize normal SCART signal transmission is proposed to solve this problem, and the HDMI interface can also transmit normal HDMI signals. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a device for multiplexing and transmitting SCART and HDMI signals through an HDMI interfac...
