Digital television - Wikipedia, the free encyclopedia All early SDTV television standards was analog in nature, and SDTV digital television systems derive much of their structure from the need to be compatible with analog television. Today most viewers receive digital television via a set-top box, which decodes the digital signals into signals that analog televisions can understand, but a slowly growing number of TV sets with integrated receivers are already available. In particular, the interlaced scan is a legacy of analog television. en.wikipedia.org /wiki/Digital_television   (1655 words)

Enhanced-definition television - Wikipedia, the free encyclopedia A standard definition television signal is broadcast with interlaced frames and is commonly referred to as "480i" or "576i". Enhanced-definition television, extended-definition television, or EDTV is a CEA marketing shorthand term for certain television formats. Prior to the 2004–2005 television season, the Fox Network was broadcasting in EDTV in the U.S. As of the 2004–2005 season, they have begun broadcasting in 720p, an HDTV format. www.wikipedia.org /wiki/EDTV   (143 words)

Television receiver compatible with both standard system television signal and high definition television signal - Patent 5132793 A television receiver according to claim 7, wherein said discriminating means discriminates a standard television signal or a high definition television signal from the received signal according to a horizontal scanning of the received signal. A television receiver according to claim 4, wherein said interpolation circuit means enables interpolation between scanning lines of each field of the received high definition television signal to thereby make a number of scanning lines per field substantially equivalent to that of the received high definition television signal. A sequential scanning conversion circuit of a high definition television signal according to the present invention has a feature that the MUSE signal is not completely decoded to reproduce the interlace high definition television signal but a sequential scanning television signal of one field is produced by using an interlace television signal of one field. www.freepatentsonline.com /5132793.html   (5625 words)

Standard-definition television - Wikipedia, the free encyclopedia Standard-definition television or SDTV refers to television systems that have a lower resolution than HDTV systems. The term is usually used in reference to digital television, in particular when broadcasting at the same (or similar) resolution as analog systems. The latter two were originally developed for HDTV, but they have proved to be more often used for their ability to deliver multiple SD video and audio streams via multiplexing, than to use the entire bitstream for one HD channel. www.wikipedia.org /wiki/Standard_definition_television   (182 words)

fcc96493.txt The DTV Standard we are adopting not only does not impose any impediment to the display of films in their original aspect ratios, but to the extent that resolution of displays is improved and a wide aspect ratio is adopted by consumers, the display of films in their original aspect ratios might be promoted. We estimate that the total number of commercial television stations with 4 or fewer employees is 132 and that the total number of noncommercial educational television stations with 4 or fewer employees is 136. This standard is a modification of the ATSC DTV Standard proposed in the Fifth Further Notice of Proposed Rule Making and is consistent with a consensus agreement voluntarily developed by a broad cross-section of parties, including the broadcasting, consumer equipment manufacturing and computer industries. www.fcc.gov /Bureaus/Mass_Media/Orders/1996/fcc96493.txt   (10952 words)

High Definition Television The current FCC standards for high-definition television are based on work done by the Advanced Television Standards Committee (ATSC). Popularly known as high-definition television or HDTV, this is a system of transmitting and viewing images (and hearing audio) vastly different from the old NTSC system we've come to know and love over the past 50 years. Its goal was to come up with both a higher resolution and widescreen version of television, and they've done that in several different ways that leave the ultimate standard defining to the producers and broadcasters who buy the equipment. svconline.com /mag/avinstall_high_definition_television   (1599 words)

The ATSC Standard The ATSC standard was adopted and is being implemented by the FCC. The conventional TV standards (525/60 and 625/50) and the related monochrome-compatible color encoding concepts (NTSC, PAL and SECAM) represent a cost/performance choice based on the technologies of the 1930s, 1940s and 1950s. The development of the advanced television concepts was entrusted to the Advanced Television Systems Committee (ATSC), a private-sector organization of corporations, associations and educational institutions. www.ibcnews.com /html/2000/July/features/ATSC_Standard.htm   (697 words)

SDTV Standard definition television (SDTV) is the basic quality of digital television.

DTV and HDTV: Digital Television Explained In order for his digital TV receiver to operate on all these different standards, the machine will have to electronically complex (translation: expensive) whether it can display high definition television imagery or not. The circuitry will have to assure that whatever signals are received in high or standard definition, and regardless of picture shape, and regardless of how many channels of audio are transmitted, something will appear on the TV screen and something will come out the speaker. The 1080i high definition standard to be used by NBC and CBS when it broadcasts DTV will be interlaced as opposed to progressive scan. videoexpert.home.att.net /artic3/253dtv.htm   (4647 words)

The Other DTV Page 1 - Talkbacks - Designtechnica Two dueling high-def-capable DVD formats will be upon us by the year’s end, but standard-definition DVD will remain the standard, so to speak, until one of them emerges victorious, and that may take a while. After all, as a home theater technology critic, I spend a large proportion of my time trying to convince the public that HDTV, or high-definition television, is worth the investment. To the founding fathers of DTV, looking to name a lower-resolution format, “standard definition” sounded more appetizing than “low definition” or “sour-milk definition.” news.designtechnica.com /talkback51.html   (502 words)

AudioVideo101.com - Audio/Video Dictionary In order to fit a movie picture on a "square" television screen, portions of the image are cut off and discarded (pan-and-scan) or the movie is presented in its full width with black bars above and below the image (letterbox). Movies for theater release are filmed in a wide aspect ratio different from that used in analog television sets. The wider aspect ratio featured with some forms of SDTV (16 units wide by 9 units tall versus the more square 4 units wide by 3 units tall used with NTSC analog television programming) allows movies to be presented in their full width, widescreen format. www.audiovideo101.com /dictionary/sdtv.asp   (476 words)

Alerts/Broadcast & Cable Industry Contributions/July 6, 1998 Members of the House and Senate Commerce Committees are benefiting from a fight between the broadcast and cable industries over the future of high-definition television (HDTV). An alliance between Microsoft and media mogul Rupert Murdoch's Fox Television is also threatening to scuttle the arrival of high-definition television. (Microsoft wants to start offering interactive services through cable television by selling a compact version of its Windows operating system to the manufacturers of digital set-top boxes - which it claims would be unaffordable with HDTV). www.opensecrets.org /alerts/v4/alrtv4n26.asp   (717 words)

HDTV : High Definition Television HD television (HDTV) offers far superior picture quality compared to standard definition television (SDTV), but requires substantially more bandwidth to deliver.
