Answer . You can connect your standard definition TV to your satellite receiver in a couple of ways. First, if your TV has composite video/audio inputs (yellow, red, and wh…ite RCA jacks), you can connect to these inputs using the composite video outputs of the satellite receiver. Another alternative is to use the standard coaxial cable output from your satellite receiver to connect to the 75ohm antenna input on your TV. *Note: Neither of these connections will display high definition programming on your standard definition TV. The TV is only capable of standard definition, so you will see a clear picture, but it won't be true high definition, regardless of the input signal's definition.
Answer . I read in an electronics catalog about "What do I do with my TV when it is not HD compatible?" I continued to read since I was wondering the same thing and apparen…tly the federal government is standardizing HD in February of 2009. This should help to dramatically lower the prices of such HD devices like blu-ray players and HD-DVD players and probably current gerneration video game consoles.
High definition TV is the latest big thing in the television world and is an improvement in resolution over standard definition. Here are some numbers that explains it:. Stan…dard defintinion uses 480 lines (in the Americas) or 576 lines (Europe) to make up the television picture. The shape of SD pictures is normally 4 wide x 3 high although parts of Europe have now moved to 16 x 9 for standard definition (UK and Germany, primarily although other coutries are using 16 x 9 SD to a lesser extent). High definition uses 720 lines, 1035 lines or 1080 lines to make up the picture. All HD pictures are 16 x 9. The extra lines and the higher number of pixels that make up each image mean that about 5 times the amount of data is required compared to standard definition. This is where the better quality come in.. Another difference is the way the picture is built up. SD signals use interlacing, a technique that delivers odd numbered lines in one pass, then even numbered lines in the next pass. Together, the two fields make a complete frame. Interlaced signals are identified with an "i" after the number. SD signals are therefore 480i and 576i. A complete image is shown 25 or 30 times each second.. HD signals are currently 1035i, 1080i and 720p. The 720p signal is a progressive display, with the complete frame delivered in a single pass. There are 50 or 60 complete frames each second. Although the number of lines is less than the 1080i version, there are double the number of frames. 720p is therefore considered better for sports and fast moving images, while 1080i is preferred for movies - Broadcasters have varied opinions on the formats and applicaitons.. Finally, 1080p is making an appearance. This is 1080 lines but with a full frame delivered 50 or 60 times each second. Broadcasters are looking at the technology but at present, they are a number of years away from adopting it as a standard.
A HD TV has HD video ports and an RCA or Coaxial cable video ports on it. The HD video ports are colored red, green, and blue, and since you have a standard definition satilli…te receiver, you won't be using them. RCA ports have red, white, and yellow tips, with the yellow cord transfering video and the red and white cords carrying sound. These should be located near the red, green, and blue video ports for the HD connection. A Coaxial cable connection has a chrome screw-like ext
High definition television uses far more data to create images than standard definition. It's about 5 times the amount of data in fact. The higher data rate allows the image t…o be generated with more pixels to produce a crisper image. In North America, standard definition has always been broadcast with a 4:3 aspect ratio. In Europe, 16:9 aspect ratios were introduced in the early 1990s so the majority of European content has been created in wide screen format for a number of years. HD television is always 16:9 and there is no standard for 4:3 ratio when using HD. The standard definition resolutions are as follows: NTSC (North America) is 640 x 480 pixels with a 4:3 aspect ratio PAL (Europe) is 720 x 576 with either a 4:3 aspect ratio or 16:9 aspect ratio High definition signals are: 1280 x 720 pixels with a 16:9 aspect ratio 1920 x 1080 pixels, also using 16 : 9 aspect ratio.

IPTV is delivery method. It is sending TV signal over IP(internet protocol). Actually, it is about sending video over IP network. HDTV is just a quality of video content. High… definition means higher resolution = better picture quality. With IPTV method you can transmit signals like SDTV, HDTV and other video content.
High definition television is defined by the HDTV standards of 1080 line and 720 line images. Any image format that uses these line counts is regarded as HD. 1080i (interlaced… image) and 1080p (progressive scan) are both HD signals even though 1080p uses twice the data rate. Television broadcasters offering HD content will always use one of those two line counts. 1035 line was also used for a short time but is not now used by any mainstream broadcaster.. Higher resolutions are used in some production environments with 2000 and even 4000 lines being used. These are exclusively used away from the broadcast chain such as film production. Even if the higher resolutions are used within a television production, the resolution is used only for editing purposes and the production will then be broadcast in 1080 or 720 line formats.. It is worth noting that 1080p is not currently used for television broadcast although it can be found on DVDs and other graphics devices such as PCs for example. It is expected that 1080i will remain the HD standard for broadcast for a number of years as live production equipment supporting 1080p is not readily available and the bandwidth required for broadcast is prohibitive at present.
\nMost certainly, HD and SD formats can and will co-exist. We are in the very early stages of HD broadcasting despite it being developed over the last two decades. Only now …is it becoming commercially viable. The move towards HD is driven by costs: Consumers are unwilling to pay high premiums for HD and broadcasters will not commit to HD broadcasting until they can see a return on the investment.\n. \nProducing HD material increases production costs several times over. Better sets, make up, lighting and equipment are all required to make the best of HD content. Studio equipment typically has a life of 10 years or more so we can expect standard definition studios to be around another ten years from now. Broadcasters will be reluctant to refit studios before they reach the end of their natural life, so SD production will also be with us for another decade.\n. \nMany specialist and low budget channels have no budget and indeed, no requirement to move to HD. Those minor channels will be moving to HD only when HD equipment costs are in line with SD equipment. That's a few years away.\n. \nAlthough HD in the home is becoming more common, by no means every home will have HD in the foreseeable future. SD broadcasts will be required for SD homes for many years to come. In the UK, color television was rolled out by the early 1970s. It took 40 years before the old monochrome transmitters were finally turned off after that roll out.\n. \nHD signals take 5 times the bandwidth of SD. As broadcasters struggle to find space on cable and on the transmission spectrum for new HD channels, SD will still be used to allow the wide range of channels that we expect.\n. \nFinally, archived material is SD. It will always be SD. Although one day, it will be upconverted to HD for broadcast, this will not improve the quality of the material and there is no justification for HD broadcasts when a channel relies heavily on older archived material.\n. \nAll HD televsions are capable of displaying SD signals and there is no pressure on broadcasters to move to HD just for compatibility reasons.\n. \nAs a personal view, I do not believe that SD will become scarce for another decade. Perhaps, in 15 years, we will have moved almost fully to HD. As I write this in 2009, I will review this answer in 2019 and 2024 to see how close my prediction is to the reality of those future times.

120 is better at making a picture with a lot of horiz. movement, like sports.
High Defintion films have much clearer pictures if played in a high definition player on a high definiton television. Also the screen makes the picture brighter.
