Most 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. Producing 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. Many 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. Although 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. HD 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. Finally, 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. All HD televsions are capable of displaying SD signals and there is no pressure on broadcasters to move to HD just for compatibility reasons. As 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.

Co-ax cable is quite capable of carrying HD signals as part of a domestic cable service. However, optical fiber is now far more cost effective than copper so it si increasingl…y used for trunks with copper links carrying signals the last few feet into a home. Some are now taking fiber right into the home. Regarding video signals within the home, co-ax cable is used to carry composite video (standard definition color signals) and this will not carry HD signals. This is purely because coaxial interfaces for HD in domestic equipment. Coaxial cable is still used widely in broadcast environments to carry SD and HD signals.
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 white 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… apparently 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.
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.

The set of X1, X2, ..., XN is called X. Given that mean(X), is the sum of all X divided by N, the variance of X is mean((Xi - mean(X))2). The standard deviation of X is the sq…uare root of the variance.
