Fig. 2. Local HDTV News can bring the highest image quality of any
delivery system to the home audience. The ONLY lossy stage from the
live HD camera output to the home HD display input is the ATSC codec
process. A great opportunity!
A live news studio HD camera supplying HD-SDI through master control directly to
the ATSC encoder, then linked to the transmitter, 8VSB modulated, and beamed to
the home without any server compression, with no video tape generation loss, no
contribution chain artifacts. Only encoded once with ATSC!
When is the right time for HD News for your TV station?
The following two statements have a high probability of being true:
Your TV Station will gain audience share by the transitioning to
local HD news at an early time
Your TV Station will lose audience share year by year if you wait
to do local HD news until 2010
We think you ought to spend significant efforts in 2007 to seriously investigate your
TV station’s options by in-depth analysis of the financial implications in each year
from 2007 through 2010 by (a) going to HD news and (b) not going to HD news. In
the end, we believe that earlier is better than later, and that 2007 will be a good year
for starting your transition to HD ENG and HD news.
