Definition
The term "high definition" refers to the resolution, or more loosely to media capable of similar sharpness, such as photographic film and digital video. High Definition TV(HDTV) potentially offers a much better picture quality of traditional television. NTSC system, established in 1941, were high definition only in comparison with previous mechanical and electronic television systems, and NTSC, with the later European 625-line PAL and SECAM, is described as standard definition today.
TV
While some early analog HDTV formats were broadcast in Europe and Japan, HDTV is usually broadcast digitally because digital television (DTV)Broadcasting requires much less bandwidth if it uses enough video compression. To get a better HDTV picture requires a high-definition (HD) signal. Since 2007, customers such as broadcasters or cable TV provider can choose to HD signals in a premium band that requires higher cable fees rise. HDTV is less than twice the linear resolution of standard definition television (SDTV), so that many more details than the analogue TV or on a regular basisDVD.
Resolution
It should be noted that while HDTV is used more as a theater as a traditional television, 35 and 70 mm film projectors in movie theaters still have the highest resolution and best image quality on large screens. Digital NTSC-and PAL / SECAM-like signals (480i60 and 576i50 respectively) are transmitted at a horizontal resolution of 720 or 704 "pixels." In Australia, the 576p50 format is also considered a HDTV format because it has doubled temporalResolution although the use of progressive scan. For example, you can use a 72 "projection HDTV 1920 × 1080 resolution from $ 2500 to $ 5000, depending on the make and model.

Satellite services and cable TV providers offer an increasing number of HDTV feeds. Satellite TV companies such as Optimum, DirecTV, Sky Digital (In the United Kingdom and Ireland) and HDTV DishNetwork offer customers an upgrade.

Technology
While high definition has joined a reality for many consumers, the technical language with this exciting new technology caused much confusion. The development of display technology, a new television has emerged in a different way, a new TV"Paragon" was created. It does not require a degree in TV technology.
Furthermore, the lack of enthusiasm for co-operation between broadcasters, cable / satellite providers and manufacturers has injected further confusion for retailers, such as HDTV and consumers to buy products, how to use them to sell and what programs are currently available in HDTV . On the other hand, a high-resolution source require more bandwidth than is available to be transferred withoutLoss of fidelity.
