ATSC 3.0 channel lineups?

Post by mm650 »

Wondering if SD will be providing channel/lineup information for ATSC 3.0 channels, and if so how they will appear.

For my application having the modulation included in the station ID / channel map would suffice, though I can also see this potentially causing problems for clients that don't expect to have to pay attention to the modulation.

The HDHomerun adds 100 to the virtual number of ATSC 3.0 stations so people watching on devices that don't support AC-4 audio or interlaced HEVC can still tune to the ATSC 1.0 version. The actual ATSC 3.0 signal uses the same virtual numbers as the ATSC 1.0 channels so most NextGen TVs will display the ATSC 3.0 versions instead of their ATSC 1.0 counterparts.

i.e. On a real NextGen certified TV directly connected to your antenna those HEVC channels will appear as 3.1, 10.1, 13.1, 19.1, 40.1 and 58.1.
