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.

Cox Broadcasting
FOX Television
Hearst-Argyle Television

These broadcasters support the use of AFD to control the aspect ratio of its programming for their analog (SD, 4:3) 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: clarence.hau@nbcuni.com.
