Buffalo Gap Saloon Eatery (upstairs)

FCC DTV Repack and ATSC3 Considerations – Single Frequency Networks (SFN)

The now concluded FCC DTV Channel auction and subsequent repack channel assignments put into play a multi-year plan/project to rechannel approximately 1000 full power DTV stations.  More opportunities have been added for channel sharing and LPTV/translator operations into the future.  This channel changing may require multiple antenna and tower modifications such as broadband full-channel slot antennas to minimize tower loading.

Additional intrigue is added by a closely scheduled adoption of a channel-incompatible transmission update called ATSC3, a successor to the 20 year old

ATSC1 now on the FCC broadcast DTV airwaves.  The FCC intends to allow ATSC3 transmission on a voluntary basis and the chase is on to make this a commercial success.  ATSC3 is the newest of digital video and data payload transmission systems and incorporates upgrades to adaptable OFDM modulation, SFN coverage advantages, IP transport, 4K HEVC Video, AC4 Immersive audio, and more.
