BPR-4 — Application Procedures and Rules for Television Broadcasting Undertakings
Within 400 km of the Canada-United States border, television broadcasting allotments and assignments in Canada are subject to the terms of the Working Arrangement for Allotment and Assignment of VHF and UHF Television Broadcasting Channels under the Canadian-U.S.A. Television Agreement of 1990.
The Working Arrangement between the Federal Communications Commission (FCC) and Industry Canada (formerly Department of Communications) states the basis upon which both Administrations consider responses to border area allotments and assignments. It also defines technical criteria for the notification of television allotments and assignments. The working arrangement also contains lists of the Canadian and U.S.A. allotments within their respective coordination zones. These lists are updated annually.
Within 370 km of French Territories of Saint-Pierre and Miquelon, the establishment of television undertakings in the band 174-216 MHz (channels 7-13) in Canada is subject to the terms of the Memorandum of Understanding between l'Office de Radiodiffusion-Télévision Française and Industry Canada.
Multipoint Distribution Television Systems (MDS-TV) in the 2596-2686 MHz frequency band, that are within 80 km of the Canada/United States border, shall comply with the domestic criteria and the agreement of understanding between Canada and the U.S.A. The terms of the agreement are contained in the document entitled General FCC/DOC Understanding Concerning the Co-ordination of the 2500-2686 MHz Band within 80 km (50 miles) of the USA/Canada Border, dated March 23, 1989. Due to channel sharing in certain border city locations, the number of channels available for use in Canada will be limited. In these areas, the channels will be shared between the broadcasting and the fixed services in a manner which differs from those set out in Table 1 of the Appendix 11. As an example, undertakings in the Windsor, Ontario area are to use the following polarizations:
- channel groups A, B, C and D and channels G-3 and G-4 vertical polarization,
- channel groups E, F and H and channels G-1 and G-2 horizontal polarization.
Section B: Preparation of Technical Submissions Supporting Applications for TV Broadcasting Stations Using Primary Assignments1

A description of the technical equipment in compliance with the minimum requirements specified in Section 5.3 of BPR-1 shall be submitted at the latest prior to on-air tests for the approved facility. If unattended operation is proposed, a statement that the unattended operation meets the minimum requirements of Section 5.3 of BPR-1 is required.
Stations proposing to insert signals into the vertical blanking interval (VBI) should refer to Section 4 in Broadcast Transmission Standard 3 (BTS-3). If only Ghost Cancelling Reference (GCR) signals are planned, approval to transmit these signals is not required. If other signals and services are planned, a description of the type, location and signal or data format should be provided. The analysis should also show that no harmful interference is caused to the reception of regular television service. If a service within the VBI is intended for the reception by the general public, notification to the CRTC is required prior to the transmission of the signal.
This section outlines the technical requirements for stereophonic and multiplex operation in the aural baseband of the television transmitter. TV broadcasting stations proposing stereophonic and/or multiplex subcarriers shall meet the requirements of this section and Broadcast Transmission Standard 3 (BTS-3), when the station operates the aural transmitter in a stereophonic or multiplex mode.
B-4.2.2 Use of Aural Baseband Subcarriers
TV broadcast stations may transmit subcarriers and signal within the composite baseband of the aural transmitter for the following purposes:
- stereophonic, biphonic, quadraphonic, etc., sound programs;
- transmission of signals relating to the operation of the station such as relaying broadcast material, remote cueing, order messages and telemetry signals from the transmitting plant;
- transmission of pilot or control signals to enhance the station's program service such as activation of noise reduction decoders in receivers, for any other receiver control purpose, or for program alerting and program identification;
- subsidiary communications services;
- any other services authorized.
B-4.2.3 Stereophonic Aural and Multiplex Subcarrier Operation
A broadcasting station may transmit multichannel aural programs upon installation of multichannel sound equipment. Prior to the commencement of multichannel broadcasting, the equipment and transmission system shall be measured to ensure compliance with the requirements of this section and Broadcast Transmission Standard 3 (BTS-3).
Multiplex subcarriers may be transmitted on a non-interference basis to broadcast programming. Transmissions shall comply with the requirements of this section and Broadcast Transmission Standard 3 (BTS-3).
Subsidiary communications services are those transmitted within the TV aural baseband signal but do not necessarily include services relating to the main program broadcast.
The holder of the broadcasting certificate should retain control over all transmitted material with the right to reject any material deemed inappropriate or undesirable.
The definitions applicable to multichannel television sound transmission appear in Broadcast Transmission Standard 3 (BTS-3).
B-4.2.5 Changes in Equipment
The addition of stereophonic or subcarrier generators to a type-approved transmitter is acceptable.
Mechanical or electrical alterations and adjustments to existing approved transmitters to accommodate stereophonic sound or subcarrier operation will be permitted provided that the following conditions are met:
- the stereophonic or subcarrier generator is designed for interfacing with the transmitter;
- alterations and adjustments to the transmitter are based on the recommendations of the transmitter manufacturer and are implemented by qualified persons;
- performance measurements shall be made to ensure that the system satisfies the applicable requirements of Broadcast Transmission Standard 3 (BTS-3);
- the transmitter, after alteration shall be certified by a professional engineer to be capable of equaling or bettering the performance requirements of the original approval specification.
Undertakings proposing to insert digital data in the active video portion of the television signal should refer to Section 5 in Broadcast Transmission Standard 3 (BTS-3). The stations may only use data insertion methods that have been approved in advance by Industry Canada. The technical criteria for advance approval of methods are as follows:
- the insertion of the data shall not cause objectionable degradation to any portion of the image, to the sound or to the program-related data (close captioning) components of the TV transmission.
- emissions outside the authorized 6 MHz television channel shall continue to comply with the limits as outlined in Broadcasting Equipment Technical Standards 4 (BETS-4). Also, interference to the reception of co-channel and adjacent channel stations should not increase as a result of the insertion of the data.
Licensees of TV broadcasting undertakings wishing to initiate vertical blanking interval signals, digital data services in the active video portion of the TV signal or multiplex subcarrier operations for broadcast purposes shall notify the intended use to the CRTC prior to the transmission of the signal. The Department requires a letter indicating the intended use. The letter to the Department shall include details of the use of the vertical blanking interval signal, the method of data insertion in the active video portion or on the multiplex subcarrier system and a statement that the proposed facilities will meet the requirements set out in this section and Broadcast Transmission Standard 3 (BTS-3).
B-4.5 On-Air Testing and Broadcasting Certificate Amendment for VBI and Multiplex Subcarrier Operations
Prior to scheduled on-air testing of vertical blanking interval signals, multiplex subcarriers or stereophonic operation, the licensee shall test and certify that the installation meets the requirements of this Section.
On-air operation may commence following satisfactory testing. The Department will accordingly amend the broadcasting certificate upon notification.
In the event that the quality of the main or the stereophonic transmissions is impaired by the vertical blanking interval signal(s) or the multiplex subcarrier(s), the licensee is required to take corrective measures to eliminate the impairment. Use of any vertical blanking interval signal or multiplex subcarrier shall not interfere with main channel nor with stereophonic operation.
When the construction of the authorized facilities is complete, notice of on-air testing shall be given to the District Manager at least three weeks (unless otherwise specified in the letter of authority) prior to transmission tests. Departmental permission from the District Office is required for testing.
During on-air tests, identification of the station shall be made preferably at 15-minute intervals, giving as a minimum the call sign, channel and location of the station. In the case of rebroadcasting stations without capability to originate the aforementioned information, the broadcaster will be responsible for making the public aware that the new station is being tested. As an example, a notice could be placed in the local press which would explain that the broadcaster should be contacted in the event of interference difficulties that might develop. The broadcaster shall implement any instruction given by departmental representatives at the district, regional or headquarter level.
The required scope and duration of such on-air emission tests will depend to a large extent on the potential for interference that might be caused to existing broadcasting stations or other radio services. Such details of the testing shall be agreed upon with the local District Manager soon after the issuance of the letter of authority.
Following successful on-air rests, the applicant's consultant shall certify to the Department that the station is ready to commence operation in accordance with the approved technical submission and request permission to commence normal broadcasting schedule.
