Each commercial and noncommercial DTV station must file an FCC Form 317 (Ancillary/Supplemental Services Report) electronically by December 1, 2008. This filing will inform the FCC as to whether the station provided any ancillary or supplementary services on its digital spectrum during the 12-month period preceding September 30, 2008. Ancillary or supplementary services generally are defined as any services provided on the station's digital spectrum other than free, over-the-air video broadcasts.

In previous years, only licensed DTV stations were required to file Form 317. Beginning this year, however, all DTV stations must submit the Form 317, including those that are not operating pursuant to a license (i.e., those operating pursuant to Special Temporary Authority or holding a DTV construction permit).

A DTV station must file Form 317 even if it has not provided any ancillary or supplementary services on its digital spectrum during the relevant time frame. In the event that ancillary or supplementary services were provided, DTV stations must report the gross revenue collected for such services, if any, and must submit a payment in the amount of 5% of the gross revenue collected, along with a remittance form (Form 159).
