Broadcast TV's Future May Lie in Single Frequency Networks

摘要

The concept of operating two or more transmitters on the same frequency in the same geographic region is not new, but there's considerable talk within the industry about the role of similar technology in the widespread deployment of ATSC 3.0, particularly after the FCC's January decision to ease rules on DTS "spillover" that the commission believes will help NextGen TV reach its full potential. Such on-channel operation will be essential in rolling out NextGen TV, especially in terms of implementing the full feature set of 3.0, many believe. Bill Meintel, partner in the Meintel, Sgrignoli & Wallace (MSW) engineering firm, believes that broadcasters need to update their technology with SFNs.
