Signal distribution method and system

Abstract

The invention provides a signal distribution method. The method comprises the following steps: receiving an analog signal transmitted from each data channel of a HDMI, and converting the analog signal into a digital signal so as to obtain a to-be-distributed signal, wherein the format of the digital signal is outputting N bytes of data at each clock, the current clock period is N times of the standard clock period, and N is the positive integer greater than 1; performing data alignment processing on the data in each data channel of the to-be-distributed signal to obtain an aligned to-be-distributed signal; performing channel synchronization processing on the data in each data channel of the to-be-distributed data to obtain a synchronized to-be-distributed signal; multiplexing the to-be-distributed signal as a to-be-output signal with set number; respectively converting the to-be-output signals with set number into the analog signals to output. By using above-mentioned signal distribution method disclosed by the invention, the convenient signal distribution processing can be realized under low technological level.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a signal distribution 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, such as 4K TVs. [0003] The high-definition multimedia interface (High-Definition Media Interface, HDMI) 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 the high-quality audition experience. For example, HDMI1.4 already supports 4K30Hz, and HDMI2.0 increases the frame data to 4K60Hz, which makes the picture smoother, which is also the result of the increased transmission rate. [0004] Usually, one HDMI signal can be ...

AI Technical Summary

Problems solved by technology

Since HDMI2.0 requires digital circuits to run at 600MHz, in order to meet this requirement, it must be taped on a deep sub-micron process, which is very costly and complex to implement. High process cost and very difficult to develop
