SCTE and CEA standards

The article says:

In the U.S., digital cable systems with more than 750 MHz activated channel capacity are required to comply with a set of SCTE and CEA standards, and to provide CableCARDs to customers that request them.

Required by whom? 18.26.0.18 05:30, 13 Feb 2005 (UTC)

Compression Artifacts

Is there anyway we could modify the article to include a note that because it's digitally compressed artifacts are present due to the [poor] encoding?I'm pretty sure anyone with digital cable has seen them on some channels and some time,if not everyday.

I have Time Warner digital cable and constantly complain that the compression artifacts make the picture look worse than when I had regular analog cable TV a few years ago. I don't understand it...why is the video so heavily compressed? Is it because their HD signals are using up most of the bandwidth? 69.203.64.174 02:55, 17 February 2007 (UTC)[reply]

The compression artifacts are IMO the limitations of MPEG-2 compression that they use. In fast-motion and areas with high contrast, they're clearly visible but overall the digital picture is more better for most people though I too disagree. I would also like to have someone add more info on how and what type of physical cables carry the digital signal. Is an RF coaxial cable, for instance, capable of carrying digital and analog signal over the same cable? Is an RF coaxial capable of carrying a digital signal in the first place? - 221.128.201.22 (talk) 17:27, 12 September 2008 (UTC)[reply]

FCC Transition

Shouldn't there be a note that the FCC transition to digital over-the-air broadcasts doesn't affect cable subscribers since cable subscribers will still receive an analog signal over cable? The presence of that section in this article is misleading in implying that transition affects cable subscribers that don't subscribe to digital cable. —Preceding unsigned comment added by 75.62.102.43 (talk) 04:00, 8 February 2008 (UTC)[reply]

Cable is technically Satellite

All the cable boxes in a certain zone hook up to one big satellite, so really, it isn't true cable, unless it was hooked up directly to the broadcasting station and the shows were sent through the wiring to the cable box. Just though this should be pointed out on the main page. Flynn58 (talk) 18:16, 15 May 2011 (UTC)[reply]

channel requesting and possible massive privacy breach

I was unable to find answer anywhere: Is digital cable broadcasting all channels at once, or is the set-top box actually sending requests to cable operator whenever subscriber changes a channel?

If latter is the case, then cable provider knows what each subscriber watches at any particular moment - which is enabling surveillance and profiling similar to tracking on the Web and social networks. — Preceding unsigned comment added by 178.148.209.217 (talk) 18:23, 12 January 2014 (UTC)[reply]

Usually [always?] all channels are sent and box selects locally. But that doesn't preclude some boxes signalling back a change of channel selection. - Rod57 (talk) 09:05, 4 June 2014 (UTC)[reply]

change title

Confusing name - article seems to refer to a TV distribution technology rather than a type of electrical cable - Could we rename/redirect to digital cable television ? ie move this content to digital cable television and make this page into a disambiguation page - Rod57 (talk) 08:53, 4 June 2014 (UTC)[reply]
