What exactly are the defense industry implications of having a high definition television system? Could someone enlighten this area of the article? —The preceding unsigned comment was added by 204.94.202.19 (talk • contribs) 14:47, August 27, 2005 (UTC)

[edit] Over the Air Broadcast Frequency

What is the frequency range of over the air HD broadcasts? —The preceding unsigned comment was added by 71.107.39.45 (talk • contribs) 22:28, November 7, 2005 (UTC)

They use the same 6 MHz VHF or UHF channels that analog broadcasts use. Most broadcasters chose to use the additional UHF channel that was given to them for that purpose. --Blainster 20:29, 19 September 2006 (UTC)

What is the description of the antenna needed to receive over the air HD broadcasts? —The preceding unsigned comment was added by 71.107.39.45 (talk • contribs) 22:28, November 7, 2005 (UTC)

Some manufacturers have introduced special models for this purpose, but any TV antenna that matches the broadcast frequency band (VHF or UHF) will suffice. --Blainster 20:29, 19 September 2006 (UTC)
Because of ignition noise and summer "skip", few stations which have broadcast analog on channels 2-6 will be returning to these channels for their final digital channel; most will be going to UHF channels 14-51, which may necessitate installation of a UHF antenna. -Dawn McGatney 69.139.231.9 (talk) 06:28, 20 March 2008 (UTC)

[edit] Please add Actual Frequency To Article

The actual frequency ranges (and those for channels if it applies to the digital paradigm) of the entire used band. I understand VHF and UHF, but I doubt if the entire band is being used. The actual numerical range would be great to see (I believe it is same as the analog, but the guard bands an now being used). --Wallace (talk) 17:46, 18 March 2008 (UTC)

Actual Frequency Range For Digital TV in US-
Channel 2-4    54.0 -  72.0 MHz;
Channel 5-6    76.0 -  88.0 MHz;
Channel 7-13  174.0 - 216.0 MHz;
Channel 14-51 470.0 - 698.0 MHz;

[edit] ATSC tuner mandate

The article states all televisions and TV-tuning devices [must] have ATSC tuners by March 2007. But then it inexplicably says No mandates exist for availability of digital set-top boxes enabling DTV reception and display on existing analog sets. Since the set-top box is a TV-tuning device, why would it not be included in the mandate? Or does the term "set-top box" here refer only to devices interfaced to cable or satellite systems, and not to terrestrial broadcast tuners? --Blainster 20:29, 19 September 2006 (UTC)

The availability of the set-top boxes is what isn't mandated, not that they have an ATSC tuner. Madlobster 22:05, 14 January 2007 (UTC)

[edit] Cited?

I flagged this as uncited; some links to the Bills would be nice... Cubedman990 22:30, 22 September 2006 (UTC)


[edit] Codec

Just wondering, if relevant, what the codec used to broadcast digital TV in the USA is? It is discussed in the wiki for Europe, and was wondering if it should also be mentioned in this topic? Popher 18:02, 27 October 2006 (UTC)

[edit] Over the Air Broadcast Frequency

If the first digital broadcast occurred in Raleigh, NC, how did it get displayed at a Circuit City store in Dallas, TX? --Rtphokie 17:26, 5 January 2007 (UTC)

[edit] DRM

What are the DRM issues, if any, with current digital TV tech in the US? Does the current equipment allow free recording, transfer, etc; or are some operations inhibited/prevented in some circumstances? -69.87.199.100 (talk) 13:30, 19 February 2008 (UTC)

[edit] Suggestion for article rename

Since the digital transition is future event, I would like like to suggest a article remane to something like 2009 American Transition to DTV, 2009 American Analog Television shutdown, or whatever we ca come to a concensus to.--Kevin586 (talk) 22:19, 1 May 2008 (UTC)

[edit] Planning the cutoff date for analog: why February 17?

An odd date, that. Just happens to be exactly the date Pluto completes for the very first time this new millennium, its routine crossing of the Galactic Plane, the equator of the Milky Way Galaxy. Of course that routine is slow, once every 250 years or so. Predominance on such schedules must be difficult to plan.

And that after Pluto was demoted a few years ago from a plan-et, and disappeared from the radar. Now it appears to be a secretplan-et. Most likely at some future date when plans are secure, Pluto will be returned to the status of planet. SyntheticET (talk) 23:14, 6 June 2008 (UTC)
