There are two ways to receive FOX HDTV programming:
1. FOX HDTV programming may be available in select markets to some DIRECTV customers who have HD equipment and a TOTAL CHOICE® with Local Channels programming package, or the DIRECTV HD Package. It's available for eligible customers who reside in the following markets: New York, NY, Los Angeles, CA, Chicago, IL, Philadelphia, PA, Boston, MA, Dallas, TX, Washington D.C., Minneapolis, MN, Detroit, MI, Atlanta, GA, Houston, TX, Tampa Bay, FL, Orlando, FL, Cleveland, OH, Phoenix, AZ, Denver, CO, St. Louis, MO, Milwaukee, WI, Kansas City, MO, Salt Lake City, UT, Birmingham, AL, Memphis, TN, Greensboro, NC, Austin, TX, and Ocala, FL. Based on your geographic location, you will receive FOX HDTV programming from WNYW (New York) or KTTV (Los Angeles).
Please note that if you cannot see a picture on channel 88 or 89, and you live in one of the above markets, you may need to obtain a waiver from one or more non-local FOX affiliates. This can take up to 45 days to process.
2. Customers eligible for Distant Network Services who have HD equipment will receive FOX HDTV as part of their DNS subscription.
Find out if you qualify.
The second part only applies if you have DNS service in an area with no LIL service or if had DNS set up before the new law was signed.
