Interesting Facts about HDTV


HDTV stands for High-Definition Television. HD has been around for some time, first used on the analogue broadcasting platform. Today HD is used on the digital platform and is widely being adopted by a number of broadcasters, electronics companies and media regulators. There are a number of interesting facts about HD:
HD has its roots dating way back to the beginning of TV: HD has a long history having been first developed and implemented in the early 1940s. It was implemented in different resolutions and platforms, the most notable resolution was between 480p and 576p. At the time, most consumers this offered superior quality and yet there were still ground to be conquered.
Digital HDTV does more than Analogue HDTV in the same bandwidth: One of the underlying feature of digital HDTV is that it can broadcast up to 16 more channels than analogue using the same bandwidth, in some instances using even less. Also because the signal is delivered using computer code, it is processed and displayed in optimal format by the HDTV instead of the broadcaster. This is a big leap from analogue.
HDTV can multitask: This means you can watch more channels and do more on the same feed of HDTV than you can with analogue. Not only can you watch more channels, HDTV brings enhanced features, subtitles, language changes, picture resolution adjustments and others. Some HDTVs even allow you to connect to the internet while watching TV.
HDTV is bigger: Todays’ HDTVs have more screen space than Analogue HDTVs which were limited to 42 inches on the CRT platform. With LCD/LED HDTVs, that number can jump to as many as 90 inches. The viewing experience is also more detailed, requiring a closer viewing ratio as compared to analogue, creating more realism than ever before.
HDTV is cheaper and environment: Compared to CRT HDTVs which affect the environment, LCD/LED HDTVs are environmentally friendly. They are also cheaper to make and use less materials than older generation HDTVs.
HDTVs are future proof: Aside from the hype about 3D, buying an HDTV today can fool proof you for years to come as the industry evolves. It may take up to 6 years for Full HD resolution to become commonplace in the broadcasting/media platforms.
