How much difference is there in clarity with a hdtv or hdtv compatible?

I think you mend to ask about the difference between HDTV and HDMI...

Here is everything there is to know about either...

 

 

High-definition television (HDTV):
is a televisionbroadcasting system with a significantly higher resolution thantraditional formats (NTSC, SECAM, PAL) allow. Except for early analogformats in Europe and Japan, HDTV is broadcast digitally, and thereforeits introduction sometimes coincides with the introduction of digitaltelevision (DTV): this technology was first introduced in the USAduring the 1990s, by the Digital HDTV Grand Alliance (grouping togetherAT&T, General Instrument, MIT, Philips, Sarnoff, Thomson, andZenith .

While a number of high-definitiontelevision standards have been proposed or implemented on a limitedbasis, the current HDTV standards are defined in ITU-R BT.709 as 1080active interlaced or progressive lines, or 720 progressive lines, usinga 16:9 aspect ratio. The term "high-definition" can refer to theresolution specifications themselves, or more loosely to media capableof similar sharpness, such as photographic film.


The High-Definition Multimedia Interface (HDMI) is an all-digitalaudio/video interface capable of transmitting uncompressed streams.HDMI provides an interface between any compatible digital audio/videosource, such as a set-top box, a DVD player, a PC, a video game systemsuch as the PlayStation 3 or an AV receiver and a compatible digitalaudio and/or video monitor, such as a digital television (DTV).

HDMI supports any TV or PC video format, including standard, enhanced,or high-definition video, plus multi-channel digital audio on a singlecable. It is independent of the various DTV standards such as ATSC, andDVB (-T,-S,-C), as these are encapsulations of the MPEG data streams,which are passed off to a decoder, and output as uncompressed videodata on HDMI. HDMI encodes the video data into TMDS for transmissiondigitally over HDMI. Previously, the maximum pixel rate of theinterface was 165Mpixels/second, sufficient for supporting 1080p at60Hz or UXGA (1600x1200), but HDMI 1.3 increased that to340Mpixels/second, providing support beyond the highest resolutioncomputer monitors available today.

HDMI also includes support for 8-channel uncompressed digital audio at192kHz sample rate with 24 bits/sample as well as any compressed streamsuch as Dolby Digital, or DTS. HDMI supports up to 8 channels ofone-bit audio, such as that used on Super Audio CDs at rates up to 4xthat used by SuperAudio CD. With version 1.3, HDMI now also supportsvery high bitrate lossless compressed streams such as Dolby TrueHD andDTS-HD Master Audio.

The Type A HDMI Connector A HDMI (Type A) PlugThe standard Type AHDMI connector has 19 pins, and a higher resolution version called TypeB, has been defined, although it is not yet in use. Type B has 29 pins,allowing it to carry an expanded video channel for use with veryhigh-resolution future displays. Type B is designed to supportresolutions higher than WQSXGA (3200x2048).

Type A HDMI is backward-compatible with the single-link Digital VisualInterface (DVI-D) used on modern computer monitors and graphics cards.This means that a DVI source can drive an HDMI monitor, or vice versa,by means of a suitable adapter or cable, but the audio and remotecontrol features of HDMI will not be available. Additionally, withoutsupport for High-Bandwidth Digital Content Protection (HDCP) on thedisplay, the signal source may prevent the end user from viewing orespecially copying certain restricted content. (While all HDMI displayscurrently support HDCP, most DVI PC-style displays do not.) Type B HDMIis similarly backward-compatible with dual-link DVI.

The HDMI Founders include consumer electronics manufacturers Hitachi,Matsushita Electric Industrial (Panasonic/National/Quasar), Philips,Sony, Thomson (RCA), Toshiba, and Silicon Image. Digital ContentProtection, LLC (a subsidiary of Intel) is providing HDCP for HDMI. Inaddition, HDMI has the support of major motion picture producers Fox,Universal, Warner Bros., and Disney, and system operators DirecTV andEchoStar (Dish Network) as well as CableLabs and Samsung. {12434458923400}
