Problems solved by technology

Moreover, the way of wireless transmission is limited by the environment and distance
If there is a barrier between the first part 52 and the second part 54, or the transmission distance is too long (for example: greater than ten meters), the effect of wireless transmission will be greatly reduced

Embodiment Construction

[0048] The advantages and spirit of the present invention can be further understood through the following detailed description of the invention and the accompanying drawings.

[0049] Figure 4 It is a schematic diagram showing a preferred embodiment of the signal extension device 60 of the present invention. In the figure, the HDMI display signal is taken as an example for illustration. The display signal extension device 60 is connected to an HDMI display signal source 10 and a display 20 to extend the transmission distance of the HDMI display signal. The transmitted HDMI display signals can be divided into video and audio signals and display control signals. Also refer to Figure 5A and Figure 5B , audio and video signals to minimize the transmission differential signal (Transition Minimized Differential Signal, TMDS). The display control signal includes a Display Data Channel (DDC) signal, a Consumer Electronics Control (CEC) signal, a Hot Plug Detect (HPD) signal, a...

Abstract

The invention relates to a display signal extending apparatus and a method for transmitting the display signal. The display signal extending device is connected between a display signal source and a display for transmitting the display signal containing an audio and video signal and a display control signal. The display signal extending device comprises a transmission line, a differential signal output end, a differential signal receiving end, two signal conversion modules and two wireless signal transmission and receiving ends, wherein the differential signal output end is connected to the differential signal receiving end through a transmission line fro transmitting the audio and video signal. The two signal conversion modules are used for converting the display control signal and the wireless signal. The two wireless signal transmitting and receiving ends are respectively connected to the two signal conversion modules for transmitting and receiving the wireless signals.

Description

technical field [0001] The present invention relates to a display signal extension device and a method for transmitting a display signal, in particular to an HDMI display signal extension device and a method for transmitting an HDMI display signal. Background technique [0002] High Definition Multimedia Interface (HDMI) has gradually become a digital interface standard for global consumer electronics products. Various products supporting the HDMI interface, such as DVD players, set-top boxes, LCD TVs, plasma TVs, and projectors, have spread all over the world, bringing consumers a higher level of digital enjoyment. [0003] HDMI is a specification developed on the basis of Digital Visual Interface (DVI). The DVI interface is a standard interface for digital displays proposed by the Digital Display Working Group (DDWG) composed of seven companies including Intel. DVI uses small-amplitude differential transmission technology to transmit image signals to the display in the f...
