'''HD ready''' is a certification program introduced in 2005 by EICTA (European Information, Communications and Consumer Electronics Technology Industry Associations), now DIGITALEUROPE. HD ready minimum native resolution is 720 rows in widescreen ratio.

There are currently four different labels: "HD ready", "HD TV", "HD ready 1080p", "HD TV 1080p". The logos are assigned to television equipment capable of certain features.

In the United States, a similar "HD Ready" term usually refers to any display that is capable of accepting and displaying a high-definition signal at either [[Engineering:720p|720p]], [[Engineering:1080i|1080i]] or [[Engineering:1080p|1080p]] using a [[Engineering:Component video|component video]] or digital input, but does not have a built-in [[Engineering:High-definition television|HD-capable]] tuner.

==History==
The "HD ready" certification program was introduced on January 19, 2005. The labels and relevant specifications are based on agreements between over 60 broadcasters and manufacturers of the European HDTV Forum at its second session in June 2004, held at the Betzdorf, Luxembourg headquarters of founding member SES Astra.<ref>{{cite press release |publisher=SES ASTRA|date=June 21, 2004|url=http://www.ses.com/4233325/news/2004/4417198 |title=HDTV specifications and timetable agreed by SES ASTRA and industry partners from all over Europe |accessdate = January 26, 2012}}</ref>

The "HD ready" logo is used on television equipment capable of displaying [[Engineering:High-definition television|High Definition]] (HD) pictures from an external source. However, it does not have to feature a digital tuner to decode an HD signal; devices with tuners were certified under a separate "HD TV" logo, which does not require a "HD ready" display device.

Before the introduction of the "HD ready" certification, many TV sources and displays were being promoted as capable of displaying high definition pictures when they were in fact SDTV devices; according to Alexander Oudendijk, senior VP of marketing for Astra, in early 2005 there were 74 different devices being sold as ready for HD that were not.<ref>Twist, Jo. [http://news.bbc.co.uk/1/hi/technology/4361543.stm "Confusion over high-definition TV"] ''BBC News'' Retrieved on November 26, 2008</ref>  Devices advertised as HD-compatible or HD ready could take [[Engineering:High-definition television|HDTV]]-signal as an input (via analog -[[YPbPr]] or digital [[Digital Visual Interface|DVI]] or HDMI), but they did not have enough pixels for true representation of even the lower HD resolution (1280&nbsp;×&nbsp;720) ([[Engineering:Plasma display|plasma]]-based sets with 853&nbsp;×&nbsp;480 resolution, [[Engineering:Cathode ray tube|CRT]] based sets only capable of [[Engineering:Standard-definition television|SDTV]]-resolution or [[Video Graphics Array|VGA]]-resolution, 640×480 pixels), much less the higher HD resolution (1920&nbsp;×&nbsp;1080), and so were unable to display the HD picture without downscaling to a lower resolution. Industry-sponsored labels such as "Full HD" were misleading as well, as they can refer to devices which do not fulfil some essential requirements such as having [[1:1 pixel mapping|1:1 pixel mapping]] with no overscan or accepting a 1080p signal.

A UK BBC television programme found that separate labels for display devices and TV tuners/decoders confused purchasers, many of whom bought HD-ready equipment expecting to be able to receive HD with no additional equipment;<ref name=rob/> they were sometimes actively misled by salespeople&mdash;a 2007 Ofcom survey found that 12% were told explicitly that they could view analog SDTV transmissions in HD, 7% that no extra equipment was needed, and 14% that HD-ready sets would receive existing digital SDTV transmissions in HD.<ref name=rob>BBC1 TV "Rip off Britain" programme transmitted 25 November 2010 at 9:15</ref>

On August 30, 2007, 1080p versions of the logos and licensing agreements were introduced; as an improvement to the earlier scheme, "HD TV 1080p" logo now requires "HD ready 1080p" certification.
