Explain in short the HDTV and DVI standards

The HDTV and DVI standards : 

HDTV : 

Short for High-Definition Television, a new type of television that provides much better resolution than current televisions based on the NTSC standard. HDTV is a digital TV broadcasting format where the broadcast transmits widescreen pictures with more detail and quality than found in a standard analog television, or other digital television formats. HDTV is a type of Digital Television (DTV) broadcast, and is considered to be the best quality DTV format available. Types of HDTV displays include direct-view, plasma, rear screen, and front screen projection. HDTV requires an HDTV tuner to view and the most detailed HDTV format is 1080i.

 HDTV Minimum Performance Attributes:

Receiver:  Receives ATSC terrestrial digital transmissions and decodes all ATSC Table 3 video formats.

Display Scanning Format:  Has active vertical scanning lines of 720 progressive (720p), 1080 interlaced (1080i), or higher

Aspect Ratio Capable of displaying a 16:9 image1

 Audio: Receives and reproduces, and/or outputs Dolby Digital audio.

DVI : 

Digital Video Interactive:

Digital Video Interactive (DVI) was the first multimedia desktop video standard for IBM-compatible personal computers. It enabled full-screen, full motion video, and graphics to be presented on a DOS-based desktop computer. The scope of Digital Video Interactive encompasses a file format. Implementations:

The first implementation of DVI developed in the mid-80s relied on three 16-bit ISA cards installed inside the computer, one for audio processing, another for video.
Later DVI implementations only used one card, such as Intel's ActionMedia series
Compression

The DVI format specified two video compression schemes, Presentation Level Video or Production Level Video (PLV) and Real-Time Video (RTV) and two audio compression schemes, ADPCM and PCM8.[3][1].

The original video compression scheme, called Presentation Level Video (PLV), was asymmetric in that a Digital VAX-11/750 minicomputer was used to compress the video in non-real time to 30.
