Proof: go to Titantv.com, select the 'digital cable' channel line-up for 'Comcast areas 1, 4 & 5' in zipcode 60640 (chicago north side, lakefront). and check the comcast channels in the range 340-379.
lol comcast. All bets are off.
I'll simply ask, _which_ of those channels will have that extra data stream that the head-end inserted? That the cable compmany doesn't know, or care, about, and *how* does it survive the de-multiplexing and re-coding that the cable company did?
I'm in agreement with you already, I said on digital the b/w had already been consumed making it financially unviable. If you paid they'd leave it alone.
You apparently have no idea how 'digital TV' is delivered by all the major cable companies in the U.S. -- demultiplexed, and transcoded to QAM with each video stream on a separate QAM channel. I don't see any _possible_ way for an additional data stream to survive _that_, without explicit intervention/support from the cable company.
They make their own choices overiding the original broadcasters. Net neutrality is old. brandon
