Her Excellency the Governor General in Council, on the recommendation of the Minister of Consumer and Corporate Affairs and the Minister of Communications, pursuant to subsection 28.01(3)* of the Copyright Act, is pleased hereby to make the annexed Regulations defining local signal and distant signal for the purposes of subsection 28.01(2) of the Copyright Act.*S.C. 1988, c. 65, s. 63Interpretation

1In these Regulations, area of transmission means(a)in respect of a terrestrial television station(i)for an analog signal, the area within the predicted Grade B contour of the station, as determined in accordance with the method set out in the schedule, and the area within a radius of 32 km from that contour, and(ii)for a digital signal, the area within the noise-limited bounding contour of the station, as determined in accordance with the document entitled BPR-10 — Application Procedures and Rules for Digital Television (DTV) Undertakings, Issue 1, published by the Department of Industry in August 2010, and the area within a radius of 32 km from that contour;(b)in respect of a terrestrial F.M. radio station, the area within the predicted 0.5 mV/m field strength contour of the station, as determined in accordance with the method set out in the schedule; and(c)in respect of a terrestrial A.M. radio station, the area within a radius of 32 km from the principal studio of the station.SOR/2004-33, s. 2; SOR/2014-80, s. 1

Local Signal and Distant Signal

2(1)For the purposes of subsection 31(2) of the Copyright Act, local signal means one of the following:(a)in respect of the entire service area of a cable retransmitter, the signal of a terrestrial radio or television station the area of transmission of which covers all of that area; and(b)in respect of a portion of the service area of a retransmitter, the signal of a terrestrial radio or television station the area of transmission of which covers all of that portion.(2)For the purposes of subsection 31(2) of the Copyright Act, distant signal means a signal that is not a local signal.SOR/2004-33, s. 2

SCHEDULE(Section 1)Method for Determining the Predicted 0.5 Millivolt Per Metre (mV/m) Contour of Terrestrial F.M. Radio Stations and the Predicted Grade B Contour of Terrestrial Television StationsHeight of Antenna Above Average Terrain (Haat)

1The height of an antenna above average terrain shall be determined on a topographical map by(a)marking the transmitting site on the map, using the geographical coordinates of the site;(b)drawing two concentric circles with radii of 3 km and 16 km, respectively, from the transmitting site marked under paragraph (a);(c)starting at true north, drawing eight radials from the transmitting site at intervals of 45°;(d)drawing, for each radial, a profile graph for the segment of terrain between 3 km and 16 km from the transmitting site, with the eight profile graphs plotted separately on rectangular coordinate paper, the distance in kilometres as the abscissa and the elevation in metres above mean sea level as the ordinate and reflecting the topography of the terrain;(e)obtaining the average elevation of the terrain above mean sea level for each segment of terrain between 3 km and 16 km from the transmitting site by(i)using a planimeter,(ii)dividing the segment in equal sectors and averaging their respective median elevations, or(iii)averaging the elevations at a sufficient number of equally spaced points to provide a representation of the terrain; and(f)obtaining the HAAT for each radial by subtracting the average terrain elevation calculated in accordance with paragraph (e) from the height above sea level of the centre of radiation of the antenna.

Predicted Contours

2(1)For F.M. radio stations, the predicted contour is defined by a field strength of 0.5 mV/m.(2)For television stations, depending on the channel involved, the predicted Grade B contour is defined by the following field strength:(a)47 dB above 1 µV/m for channels 2 to 6;(b)56 dB above 1 µV/m for channels 7 to 13;(c)64 dB above 1 µV/m for channels 14 to 69.(3)The HAAT determined in accordance with section 1 shall be ascertained for each radial and the effective radiated power (ERP) shall be ascertained in the plane of maximum radiation (in the case of directional antennas, the ERP value in the direction of each radial shall be used).(4)The appropriate F(50,50) propagation curves (Tables I to III) shall be used with the HAAT and the ERP ascertained in accordance with subsection (3) to determine the distance from the transmitting site to the contour point on each radial.(5)The contour points determined under subsection (4) shall be joined by a smooth curve to obtain the contour.Note:The 40 dB line is the reference line for an effective radiated power (ERP) of 1 kW.Table I Estimated field strength exceeded at 50 % of the potential receiver locations for at least 50 % of the time at a receiving antenna height of 9.1 metres for channels 2-6 and FM.Table II Estimated field strength exceeded at 50 % of the potential receiver locations for at least 50 % of the time at a receiving antenna height of 9.1 metres for channels 7-13.Table III Estimated field strength exceeded at 50 % of the potential receiver locations for at least 50 % of the time at a receiving antenna height of 9.1 metres for channels 14-69.
