HD Ready - what is this format?

Are you interested in the term HD Ready? What is it, you can learn from this article. It's about the marketing term describing the correspondence of video equipment to a special standard of interaction with certain content.

HD Ready: what is it?

This term is officially used in European countries since 2005. It was then that the EICTA association announced this logo. It should be clarified that this standard was created with a special emphasis on technology to protect content from piracy. Its absence is not related to the ability of a particular device to play HD video.

Conditions

So, let's discuss the term HD Ready. What this, we were able to establish in the first section of this material. However, there are a lot of other issues related to this format that need clarification. The minimum HD Ready resolution is 720 lines, when it comes to widescreen display. This technology requires the presence in the device of HDMI or DVI inputs with support for content protection (HDCP). In addition, support for high-resolution 720p and 1080i formats is assumed. This technology does not end there.

Alternative to televisions

Many personal computers and laptops actually have a higher resolution than HD Ready technology requires. However, they can not be attributed to this class of devices in the absence of necessary connectors. Any relatively fast computer that has a display resolution of 1280x720 or higher, is capable of playing HD video, although the PC did not initially provide such an option.

The updated HD Ready logo is based on the traditional, but it adds a separate line - 1080p. This technology extends to devices with a minimum resolution of 1920x1080 and progressive scan. Here are the main technical requirements for obtaining a new HD Ready sign. This is the ability to play video formats without distortion, displaying 1080i and 1080p without re-development, support for Multisync Display, the presence of an analog input YPbPr, copy protection.

Devices related to the past generation of this technology have a number of limitations. For example, they do not display video at full resolution, which comes from an HD source. Most of these devices can not give an accurate image, without distortion in the transmission of points.

Differences from Full HD

Special logos related to this or that technology can be found on video cameras or TVs. It is generally accepted that HD Ready devices have fewer features than Full HD. In addition, they are cheaper than competitors. The main difference between these marketing terms is primarily in the quality of video. It can not be said that the difference is very significant, since it is difficult to notice with the naked eye, but it is there. HD Ready plays video with support for 1280x720p resolution. This causes some distortion in the image. Full HD supports a resolution of 1920x1080 p. At the same time there are no distortions. As for the updated logo HD ready 1080p, its characteristics are often similar to Full HD. However, they can not be called synonymous because of technical features. Often also on devices you can find data about the development of video, denoted by the letters "p" (progressive) and "i" (interlaced). The digits indicate the resolution of the image. It's about the number of points from which a picture on a video is built. Quality increases in proportion to the increase in this indicator.

It should be noted that HD is an abbreviation of High Definition, which denotes the corresponding video. This technology allows you to create, as well as broadcast data with a resolution of 1280x720 to 1920x1080.

So we've dealt with all the questions about the HD Ready format: what are these, what are the key features and what devices support the technology. This concludes our review. We hope that it will be of use to you.
