whats some cool facts about High definition television?

Rebeca Mckin: HDMI can pass video resolutions from 480i up to 1080p, however, each manufacturer determines the parameters for what is to be transferred via HDMI in their components. HDMI can be implemented on Televisions, AV Receivers, DVD Players, Blu-ray Disc Players, HD-DVD Players, HD Cable Boxes, and HD Satellite Boxes. HDMI also includes provisions for HDCP (High Definition Copy Protection). This allows content providers to prevent their programming from being illegally copied. HDMI can be adapted to DVI (Digital Video Interface), via an adapter cable or connector. However, the device that has the DVI connection must be HDCP enabled for the signal transfer to work. There are four versions of HDMI that have been developed over the years. In each case the physical connector is the same, but the content characteristics have evolved. All newer versions are backwards compatible. In other words, you can still use newer versions of HDMI with components equipped with older ! versions, you just won't be able to access the all the content features of the newer version(s). HDMI 1.0 - This is the first version of HDMI. HDMI 1.0 combines a digital video signal (standard or high-definition) with a two-channel audio signal over a single cable, such as between an HDMI-equipped DVD player and Television. HDMI 1.1 - This version adds the ability to transfer not only video and two-channel audio over a single cable, but also added the ability to transfer Dolby Digital, DTS, and DVD-Audio surround signals, as well up to 7.1 channels of PCM audio. HDMI 1.2 - This version of HDMI adds the ability to transfer SACD signals in digital form from a player to a receiver. HDMI 1.3 - This version includes improvements in both audio and video capability. With the advent of Blu-ray Disc and HD-DVD, version 1.3 adds the ability to transfer the digital bitstreams for the new high resolution audio formats: Dolby Digital Plus, Dolby TrueHD, and DTS-HD. HDMI 1.3a - In addit! ion to the above audio improvements, HDMI 1.3 and 1.3a increas! e the amount of video bandwidth that can be transferred from a source to a display. This means, that in addition to the standard 24-bit color depth we are used to, HDMI 1.3 and 1.3a have the ability to transfer color depths up to 48-bits, and can accommodate resolutions much higher than the 1080p resolution standard that is in use today. The Future of HDMI As you upgrade and purchase new audio and video components, you will notice HDMI becoming more of a standard connection option. Eventually, the cable jungle behind your home theater system will disappear, as all the audio and video cables are reduced to one HDMI cable between each component for both audio and video. This is great news for consumers, but bad news for cable manufacturers. However, cable manufacturers seem to have an answer for this dilemma; have you noticed how much more expensive HDMI cables are?
