Signal conversion device and conversion method

Abstract

The embodiment of the invention discloses a signal conversion device and a conversion method. The signal conversion device is used for being connected with a machine core board of an ultrahigh definition television and a display capable of supporting an HDMI signal, and comprises a signal receiving module, a signal conversion module and a CPU, wherein the signal receiving module is connected with the machine core board and used for receiving an initial signal output by the machine core board; the initial signal is an LVDS (low-voltage differential signaling) signal or a first V-BY-ONE signal; the signal conversion module is connected with the signal receiving module and the display separately, and is used for converting the initial signal into the HDMI signal according to an instruction and outputting the HDMI signal to the display; the CPU is in communication connection with the signal conversion module and used for transmitting the instruction to the signal conversion module. Through the signal conversion device, the machine core boards of different ultrahigh definition televisions can be matched with different displays, and the display still can normally display and output, so that research and development persons can debug the machine core boars of various ultrahigh definition televisions based on the displays capable of supporting the standard HDMI signal, the research and development efficiency is improved and the production cost is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of television, and in particular, to a signal conversion device and a conversion method. Background technique [0002] In recent years, the visual effects of ultra-high-definition televisions such as 4K televisions have broken through the limits of the human retina. Compared with traditional high-definition televisions, the picture clarity, color, and fluency of ultra-high-definition televisions have been greatly improved and improved. Ascension has won the favor of consumers in the market. [0003] THine company proposes a new data transmission method, that is, V-BY-ONE. Compared with the traditional low-voltage differential signaling (Low-Voltage Differential Signaling, LVDS), the V-BY-ONE interface can transmit higher bandwidth. , and the number of transmission lines used is less, so many TV manufacturers are actively adopting the V-BY-ONE interface. [0004] Due to different data ...
