HD ready
HD readyis a certification program introduced in 2005 byEICTA(European Information, Communications and Consumer Electronics Technology Industry Associations), nowDIGITALEUROPE.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 either720p,1080ior1080pusing acomponent videoor digital input, but does not have a built-inHD-capabletuner.
History[edit]
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 theBetzdorf, Luxembourgheadquarters of founding memberSES Astra.[1]
The "HD ready" logo is used on television equipment capable of displayingHigh 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 factSDTVdevices; according to Alexander Oudendijk, senior VP of marketing forAstra,in early 2005 there were 74 different devices being sold as ready for HD that were not.[2]Devices advertised as HD-compatible or HD ready could takeHDTV-signal as an input (via analog -YPbPror digitalDVIorHDMI), but they did not have enough pixels for true representation of even the lower HD resolution (1280 × 720) (plasma-based sets with 853 × 480 resolution,CRTbased sets only capable ofSDTV-resolution orVGA-resolution, 640×480 pixels), much less the higher HD resolution (1920 × 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 having1:1 pixel mappingwith no overscan or accepting a 1080p signal.
A UKBBCtelevision 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;[3]they were sometimes actively misled by salespeople—a 2007Ofcomsurvey 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.[3]
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.
Requirements and logos[edit]
HD ready[4]andHD ready 1080plogos[5][6]are assigned to displays (including integrated television sets, computer monitors and projectors) which have certain capabilities to process and displayhigh-definitionsource video signal, outlined in a table below.
TheHD TVlogo[7][8]is assigned to either integrateddigital televisionsets (containing a display conforming to "HD ready" requirements) or standaloneset-top boxeswhich are capable of receiving, decoding and outputting or displaying high-definition broadcasts (that is, include aDVBtuner for cable, terrestrial or satellite broadcasting, a video decoder which supportsH.264/MPEG-4 AVCcompression in 720p and 1080i signal formats, and either video outputs or an integrated display capable of handling such signals).
TheHD TV 1080plogo[5][9]is assigned to integrated digital television sets which have a display conforming to "HD ready 1080p" requirements, a DVB tuner and a decoder capable of processing 1080p signal.
In order to be labelled "HD ready 1080p" or "HD Ready" logo, a display device has to meet the following requirements:
| Requirements | HD ready | HD ready 1080p |
|---|---|---|
| Minimum native resolution | 720 horizontal lines (rows) in widescreen ratio |
1920×1080 |
| AnalogueYPbPrHD input | Yes | Yes |
| DigitalHDMIorDVIHD input | Yes | Yes |
| The HDMI or DVI input supportscopy protection(HDCP) | Yes | Yes |
| 720pHD (1280×720progressive@50 & 60 Hz) | Yes | Yes |
| 1080iHD (1920×1080interlaced@50 & 60 Hz) | Yes | Yes |
| 1080pHD (1920×1080progressive@24, 50 & 60 Hz) | No | Yes |
| Accepted video formats are reproduced without distortion | No | Yes |
| Display 1080p and 1080i video withoutoverscan(1:1 pixel mapping) | No | Yes |
| Display native video modes at the same, or higher,refresh rate | No | Yes |
