Problems solved by technology

[0004] When transmitting ultra-high-definition signals through HDMI2.0, due to the high bandwidth, as the transmission distance increases, there will be problems of signal out-of-sync and poor quality
Since HDMI2.0 requires digital circuits to run at 600Hz, in order to meet this requirement, to solve the above problems, it is necessary to tape out chips on a deep submicron process, which increases the process cost and development difficulty of developing chips

Abstract

The embodiment of the invention discloses a signal transmission method and system. The method comprises the following steps: receiving TMDS transmitted from three data channels of an HDMI, and converting the TMDS transmitted from each data channel into a digital signal of data of N bytes output by each clock; then, aligning the data of the N bytes corresponding to each data channel to generate a group of aligned data; synchronously generating a synchronized digital signal by three groups of aligned data; and finally converting the synchronized digital signal into an analog signal and outputting the analog signal. As the TMDS transmitted from each data channel is converted into the digital signal of data of N bytes output by each clock, and the current clock period is N times of the standard clock period, the digital clock frequency can be reduced, the signal transmission can be realized in a relatively low process, and thus the process cost and the development difficulty of the development chip are reduced.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a signal transmission method and system. Background technique [0002] With the continuous development of electronic technology, viewers have higher and higher requirements for picture quality, and more people begin to choose high-definition TVs or even ultra-high-definition TVs (eg, 4K TVs). Nowadays, 4K ultra-high resolution has become a trend in the industry, and many display devices and video capture devices have begun to add support for 4K resolution. [0003] HDMI (High-Definition Media Interface, high-definition multimedia interface) can transmit ultra-high-definition signals, such as 4K signals and 8K signals. This ultra-high-definition signal has uncompressed, lossless high-resolution and real-time characteristics, which can bring users Come to high-quality listening and visual experience. For example, HDMI1.4b already supports 4K30Hz, and HDMI2.0 inc...
