Transmission issues are still near the forefront of broadcast planning
LAS VEGAS-- It’s likely that you’ll hear facts and figures about how most broadcast content is delivered to viewers by means other than terrestrial these days. And, it’s true that off-air television viewers have been declining. However, upcoming spectrum auctions, the continuing mobile TV rollout and new developments on the ATSC standard mean that transmission issues are still near the forefront of broadcast planning.
