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)

[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)
