HD TV is fast becoming the best TV broadcasting and receiving platform that is available today. As technology as evolved so has the need for the TV industry to play how to speed, most of the technology is adopted from IT and computers. The most hyped element or feature of HD TVs has been the ability to produce clearer more detailed video images. Many broadcasters and media companies have also began to adopt HD TV technology by replacing their broadcasting and filming equipment with HD TV quality broadcast equipment.
Though it is a developing segment of consumer electronics, HD television is still many years from becoming the global broadcasting standard. With the discovery and launch of HD television have come more platforms including 3D and in some countries even 4D, as well as Ultra High Definition among others. The recent Blu-Ray vs HD-DVD war was another sign that the segment is still in its early stages. To fully adopt the full benefits of an HD TV there maybe some other equipment needed. In the US, some HD TVs are able to display HD content using the need for a connection box, these options include a QAM tuner built-in and a card slot for a cable card. Other HD TV sources may include terrestrial broadcast, DVB satellite, IP TV, internet downloads and Blu-Ray discs.
Most HD TVs are capable of displaying two or three picture quality formats including 720p and 1080p, although some HD TVs can also display 1080i. There are two image process scanning methods, progressive scanning and interlaced scanning. There are also things such as refresh rates also determine what kind of image quality the HDTV produces.
There is no color standard for HD TV, until recently the color of all pixels was determined by three 8-bit color values, each representing a level of red, blue and/or green which can be used to define a pixel color. By most standards, 24 bits of color can produce about 16.7 million colors. There are some HDTV makers who have been able to create 30 bit HD TVs for a total of 1 billion colors, producing a more detailed picture.
HDTVs number one advantage of producing better picture quality is giving it a reason of becoming the new TV for the 21st century.
