刚刚查了一份台湾的技术资料,HDMI应该传输的是数字的RGB信号,此前小弟也有错误认识,一直想当然地认为是数字色差的。
HDMI支持下列编码方式的信号传输:
RGB4:4:4,
YCBCR 4:4:4
YCBCR 4:2:2
所以别一看见HDMI传输分量信号就大惊小怪,那就成修理工水准了。
要是不能传输分量信号,那才是伪HDMI呢。

6.1 Overview
HDMI allows a wide variety of explicitly defined video format timings to be transmitted and displayed. These video format timings define the pixel and line counts and timing, synchronization pulse position and duration, and whether the format is interlaced or progressive.
The video pixels carried across the link shall be in one of three different pixel encodings: RGB 4:4:4, YCBCR 4:4:4 or YCBCR 4:2:2.
The HDMI Source determines the pixel encoding and video format of the transmitted signal based on the characteristics of the source video, the format and pixel encoding conversions possible at the Source, and the format and pixel encoding capabilities and preferences of the Sink.
