You can tell that this white paper does not talk a lot about audio. There are 2
reasons: 1) in HDMI, digital audio is transmitted with digital video in the same
physical wires; 2) digital audio data rate is only about 1% of the video data rate, so
audio does not post separated challenge to the HDMI transmission and distribution
system. Of course the source and sink devices which involve the audio encoding
and decoding have a lot of to do with audio; which we don’t need to cover in this
paper.
摘自kenli的发来的文章,简单翻译一下:
本文仅用少量篇幅提及音频,有两个原因:1 数字音频信号是与数字图像信号同时在hdmi电缆中传输的 2 音频数据仅有视频码率1%的流量,对于hdmi的带宽来说根本不成问题。当然音源的编码与解码设备很重要....但总之不关hdmi的事,所以本文就不赘述了。
-----------------说不同hdmi咸菜有不同声音的可以去s了,只要符合标准都一样!
