Overview
Digital TV refers to the transmission of a broadcast signal by
encoding it as zeroes and ones to provide new and higher quality
services. It offers an amazing multimedia experience while providing
access to Internet, voice and video across the same medium. Digital
television provides crystal clear, "snow-free" and sharper
cinema-like pictures with CD-quality sound to all TVs that can receive
a minimum level signal. It can be compressed to provide multiple
channels (up to 5 channels per program) in the same bandwidth required
for one channel of NTSC television (the current standard).
This scheme allows transmission of TV programs in wide screen,
high resolution formats known as HDTV
(high definition TV) and SDTV (standard definition TV) format providing
significantly better color performance than existing analog TV systems.
It will be used by more than 1600 broadcast TV stations in the US.
Broadcasters have the ability to simultaneously transmit multiple
video programs using a single TV channel - simultaneously delivering
digital data services with TV and audio programming such as publications
(local electronic newspaper), program schedules, computer software,
specific product information, email and Internet.
Market Research
According to the International Data Corporation’s (IDC) analysis,
the total U.S. unit shipment of DTVs will increase from 570K units
to 5.57M from the year 2000 to 2004. Per the same analysis, the
total US shipment of analog TVs will decrease from 28M units to
24M units from the year 2000 to 2004.
Different DTV Technologies:
The different DTV technologies are: plasma display panels (PDPs),
liquid crystal displays (LCDs) and digital light processor (DLPs).
Market Trends
While DTV holds the promise to enhance your multimedia experience,
there continue to be conflicts over broadcasting standards. This
however does not allow for rapid product deployment since the market
is not decided over standards. But not being able to build products
and in lieu of a particular standard being accepted may lock customers
out of the market for an entire product cycle.
