ATSC 3.0 Multicast Petition Circulated

An NAB petition on clarifying FCC ATSC 3.0 multicast rules was circulated to the eighth floor last week, according to the FCC website and a broadcast industry official. The petition involves the “substantially similar” programming requirement for stations switching to the new standard and would make shifting markets easier, broadcasters said (see 2109300003). NAB wants certainty on which station the FCC will hold responsible for violations of rules when broadcasters are hosting each other’s channels on multicast streams during the 3.0 changeover.
