THE AFD READY INITIATIVE
AFD
Ready is
an initiative created by television broadcasters to
insure uniform
and optimum program delivery of television broadcasts
after the 2009 DTV Transition. Through this
initiative,
participants will work to increase awareness of AFD and
promote
its use throughout the television industry.
What
is AFD?
AFD - Active Format Description - has been standardized
by SMPTE,
ATSC and CEA as a method of describing aspect ratio and
picture
characteristics of video signals. It has been used by
broadcasters
to dynamically control how down-conversion equipment
formats widescreen
16:9 pictures for 4:3 displays.
Leading
up to and after the 2009 DTV Transition, cable
and satellite providers will down-convert HD broadcasts
for distribution
to their SD viewers. The primary goal of the AFD Ready
Initiative
is to drive the deployment of AFD technologies to ensure
that
the down-converted signals are displayed in the aspect
ratio that
content producers originally intended.
Principal
Supporters
The following television broadcasters have come together
to officially
support the AFD Ready Initiative.

Professional AFD Ready
ATSC
Receiver/Down-Converters
A main component of the AFD Ready Initiative is to drive
the deployment of AFD Ready cable head-end receiver/down-converter
devices. Throughout 2008 and 2009, thousands of these devices will be
installed at cable, DBS and Telco receive sites to down-convert
off-air ATSC
HD signals from your local station for their analog
viewers.

AFD Test Material
To assist with verifying the operation of DTV receivers and converter
boxes, the Consumer Electronics Association (CEA) has set up an FTP site
for exchanging ATSC encoded bitstreams with AFD. Bitstream files include
test material that CEA has created and also sample material from
broadcasters. For access to the FTP site please contact Brian Markwalter
at CEA: bmarkwalter@ce.org.
Manufacturers who need baseband HD-SDI
material with AFD in VANC should contact Clarence Hau at NBC Universal:
