FCC jurisdiction over BF and an I/O port is completely different.
First, BF, would be a mandate regarding the content of the signal which would have been a completely new jurisdiction.
Note, that the structure of the signal regarding frequency/amplitude/modulation algorithm is traditional FCC jurisdiction.
Further, any device that receives or transmits a radio frequency is regulated by the FCC. In particular for emissions, especially if a receiver. That way, bogus receivers will not interfere with other radio communications. So that includes HDTV broadcast and reception.
I guess a good question would be: who came up with the standard for composite Video, component video, IEEE-1394 MPEG2 TS, IEEE-1394 DV, HDMI x.x, DVI, S-video, and VGA. I tend to believe that you cannot fool around with those standards. If you would make one of those proprietary for your own business model, you would be breaking some regulatory law in my book. It may be that each of those has their own industry committee like modem standards.
So who would be the standards gate keep on consumer electronics? I guess that would be the FTC which got involved with bogus amplifier power specifications. Of course, consider the history of that. For years companies lied about amplifier output. Then, eventually, the FTC got involved. Considering the chaos right now with HDTV, this dwarfs the previous situation. It may be that the FTC eventually comes down on these clowns with an Iron Fist! Yeah Baby! (Austin Powers)
Maybe the FTC is the potential advocate for IEEE-1394 MPEG2-TS? (Also, a technical question: Which TS is the format for transmitting OTA HDTV, does it have any relationship to the HDMI formats? For one, an OTA receiver/tuner would have a HDMI output indicating the encryption - but is there really a conversion? What format of signal do you get when you decrypt a HDMI transwmission of an OTA TS source?)
[I love HDTV hoopla. You have to have an electrical engineering degree to understand it. I would LMAO if The Public simply shows no real interest in it including HD DVD formats.]
