I wish HDMI equipment would display a counter of digital errors. For all non-defective cables, this counter should be 0 all the time.

Does the HDMI signal provide a checksum of any kind? I was under the impression that it's just a raw TMDS bitstream of color values with no redundancy.




I read the specs myself and found out that:

  * control packets (non-video, non-audio) are protected using TMDS Error Reduction Coding (TERC4)
  * audio packets seem error-protected at a higher level (by Dolby or DTS?)
  * video packets are *not* error-protected
Wow. I am shocked. How can anyone design a high-speed video digital transport layer these days without error correction? Source: http://arstechnica.com/civis/viewtopic.php?p=6271817#p627181...
