本标准定义了1.5 Gb/s[标称]信号/数据串行接口的位串行数据结构和同轴电缆接口规范，以承载映射到1.5 Gb/s有效负载的1280x720、1920x1080或2048x1080有源像素格式。本标准定义了将并行源格式数据序列化为串行位流的方法。如果遵守参考源图像格式施加的限制，该接口还可以携带映射到1.5 Gb/s传输有效载荷的打包数据。本标准规定了适用于信号损耗不超过接收器制造商规定量的应用的同轴电缆接口，在时钟频率的一半时，典型损耗量在20 dB的范围内。

This standard defines a bit-serial data structure and the coaxial cable interface specifications for 1.5 Gb/s [nominal] Signal/Data Serial Interface to carry either 1280x720, 1920x1080 or 2048x1080 active pixel formats mapped into the 1.5 Gb/s payload. This standard defines the method of serializing the parallel source format data to a serial bit stream. This interface may also carry packetized data mapped into the 1.5 Gb/s transport payload providing the constraints imposed by the reference source image formats are observed.This standard specifies a coaxial cable interface suitable for application where the signal loss does not exceed an amount specified by the receiver manufacturer, typical loss amounts would be in the range of up to 20 dB at one-half the clock frequency.
