Gone are the days when watching favorite TV shows meant adjusting with the picture quality. Before people enjoyed their favorite TV shows even when the picture on the screen was fuzzy and blurred. The world of television has experienced a great advancement from fuzzy black and white pictures to stunning high-definition images with life-like depth and realism. HD services have truly changed the way of watching television and perceiving things.
HIGH DEFINITION SERVICES- EARLY YEARS
The roots of HD services date back to 1970 with the research held by NHK (Japan Broadcasting Corporation). The SMPTE (The Society of Motion Picture and Television Engineers) published recommendations on the definition of wide screen format and 1100-line scanning structure. A proposal approved by Federal Communications Commission became the mandate Advanced Television Systems Committee standard for terrestrial HD services broadcasting.
HIGH DEFINITION SERVICES-TODAY
Today HD services potentially offers much clear picture and sound quality than what standard services provided. Now the picture on the screen is less blurred and fuzzy, sound is clearer, smoother motion, rich and natural colors. In HD services, the information transferred is more than 6 times which results in a huge improvement in sound and quality. HD programming and films are presented in 16:9 widescreen format. This wider aspect ratio makes the image appear more realistic.
