HD ready
HD ready is a certification program introduced in 2005 by
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 720p, 1080i or 1080p using a component video or digital input, but does not have a built-in 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.[1]
The "HD ready" logo is used on television equipment capable of displaying 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
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;[3] they were sometimes actively misled by salespeople—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.[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
HD ready[4] and HD ready 1080p logos[5][6] are assigned to displays (including integrated television sets, computer monitors and projectors) which have certain capabilities to process and display high-definition source video signal, outlined in a table below.
The HD TV logo
The HD TV 1080p logo[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:
