In a letter to the CRTC last month, Industry Canada says it has put a moratorium on the use of television channel 51, the current upper limit of the broadcast spectrum band.
The Canadian move follows similar actions by the U.S. Federal Communications Commission (FCC) last August.
Over-the-Air (OTA) television signals, sometimes referred to as terrestrial or conventional television signals, are radio waves transmitted from high towers to aerials mounted on homes or to small set top antennas.
While virtually left for dead ten years ago, OTA television has had a renaissance in North America over the last few years after governments in Canada and the United States legislated conventional television broadcasters switch their mode of signal transmission from 1950′s era analog to 21st century digital.
In a broadcasting decision handed down today, the CRTC has approved an application to add a digital transmitter for CHCH-TV to serve London Ontario.
