MEDIA BUREAU ANNOUNCES THE MODIFICATION OF THE TELEVISION 
INTERFERENCE ANALYSIS PROGRAM 
In its DTV Report and Order in MB Docket No. 07-91, the Commission adopted rules and 
procedures for Post-Transition interference standards and analysis methodology when processing 
applications. 1 The Commission stated that for approximately a year after lifting the filing freeze, we 
would protect all stations’ DTV Allotment Table Appendix B facilities, after which we would protect 
each station’s new DTV Allotment Table Appendix B facilities’ coverage only until the station had a CP 
or license for its post-transition operation, at which time we will limit its interference protection to its 
authorized coverage area. 
By Public Notice, on June 20, 2008, the freeze was lifted on the filing of digital maximization 
applications.2 Accordingly, going forward, the DTV Allotment Table Appendix B facilities will no longer 
be protected. Thus, the Commission’s interference analysis program has been revised to exclude the 
Appendix B facilities from the analysis, except that they will continue to be used for determining baseline 
service and interference populations. Furthermore, the revision of the interference analysis program 
includes use of the vertical radiation pattern established by LPTV Report and Order for Digital and 
Analog Class A television stations.3

Division of the Media Bureau at (202) 418-1600.
