Defining Tv Moments With Hdtv



Television technology as​ we know it​ today has evolved tremendously from its inception in​ the​ late 1800s. Inspired by the​ success of​ the​ inventions of​ Bell and​ Edison in​ bridging wide distances, scientists became more and​ more intrigued by the​ possibility of​ ‘distance vision’ or​ the​ ability to​ simultaneously see someone in​ another part of​ the​ world moving and​ talking while one is​ in​ another location.

With their relentless efforts, it​ wasn’t long before American scientist Charles Jenkins and​ Scotsman John Baird were able to​ put on air in​ England and​ the​ U.S their first television programming of​ silhouettes and​ stick figures. This was followed by several major breakthroughs which eventually led to​ the​ development of​ television technology as​ we know it​ today.

• 1927 — Bell Laboratories transmitted the​ first live picture with voice broadcast.
• 1939 — RCA unveiled its first line of​ television receivers in​ its World’s Fair.
• 1943 — the​ National Television Standards Committee (NTSC) technological standards for​ black and​ white TV were established.
• 1957 — Robert Adler invented the​ first practical remote control called the​ ‘Space Commander’.
• 1960s — Color television programming was launched.
• 1962 — Television signal via satellite was launched for​ the​ first time
• 1970s to​ 1980s — the​ highly efficient fiber optic cable was introduced significantly improving delivery of​ television programming and​ paving the​ way for​ the​ entry of​ digital television technology.
• 1990 — Closed-caption television was created for​ the​ hearing-impaired.
• 1994 — High Definition Television (HDTV) standards were established along with a​ plan for​ the​ eventual phasing out of​ analog television and​ the​ conversion to​ the​ digital format
• 1998 — the​ first HDTV sets were sold in​ the​ market.


What is​ HDTV?

High Definition TV or​ HDTV is​ a​ digital broadcast standard that insures the​ viewer the​ ultimate in​ viewing quality and​ sound. it​ is​ one of​ 18 voluntary standards for​ digital television set by the​ Advanced Television Standards Committee (ATSC), which provides guidelines on the​ levels of​ quality to​ be followed for​ sound and​ video encoding and​ transmission. of​ these 18 standards, which are all superior to​ the​ analog technology commonly used in​ television today, HDTV holds the​ highest rank. the​ HDTV broadcast format, therefore, is​ the​ most superior. However, purchasing an​ HDTV-ready TV set does not mean that one automatically gets to​ enjoy the​ benefits of​ this technology. to​ be able to​ enjoy HDTV, one must also be viewing a​ program that has been digitally prepared. in​ some cases, one needs a​ set-top converter to​ convert the​ broadcasts from analog to​ digital.

Whatever it​ is, one cannot escape the​ fact that the​ digital age is​ upon us and, whether or​ not we are ready, it​ will just be a​ matter of​ time before the​ analog broadcasts we have grown so used to​ is​ phased out and​ digital TV becomes the​ standard.

For an​ avowed TV addict who knows nothing about digital TV, the​ prospect is​ daunting. the​ need to​ understand DTV and​ HDTV therefore is​ now.
