一种基于同轴电缆的高清监控数据发送方法

A High Definition Monitoring Data Transmission Method Based on Coaxial Cable

本文提出了一种基于同轴电缆的高清监控数据发送方法,可以实现在现有的基于同轴电缆的老旧系统中传输高清数字数据(图像和音频),支持720P格式。通过自定义数据格式,优化了数据格式,并降低了数据发送和接收的复杂度。摄像头传感器传输带宽定义为74.25M×20b,同轴电缆传输速率为1.485 Gb/s。本设计仅使用现有的同轴电缆系统,而不使用网线,从而大大降低了成本。

In this paper,a high-definition monitoring data transmission method based on coaxial cable is proposed,which can transmit high-definition digital data(image and audio)in the existing coaxial cable-based old system,and can support 720P format.By customizing the data format,the data format is optimized and the complexity of data sending and receiving is reduced.The transmission bandwidth of camera sensor is defined as 74.25M×20b and the transmission rate of coaxial cable is 1.485 Gb/s.This design only uses the existing coaxial cable system,but does not use the network line,thus greatly reducing the cost.
