CBC/Radio-Canada has selected Dielectric Communications to build a high-power television channel combining system for installation at the CN Tower in Toronto.
Dielectric is partnering with Rohde & Schwarz, the digital television transmitter provider, for the project.
The new system combines two CBC/Radio-Canada digital television (DTV) signals with one CBC analog signal and one analog signal from public broadcaster TV Ontario into a common output feeding an existing broadband antenna.
The combiner is designed to allow for additional channels in the future and incorporates a number of innovations developed by Dielectric. The installation may be the first time that N-1 and N+1 channel pairings are being combined in close proximity within the same combiner. In effect, CBC/Radio-Canada is inserting two NTSC analog and two 8VSB digital signals into a six-channel spread, according to a CBC/Radio-Canada spokesman.
