Call for comments on measures to control the loudness of commercial messages
The Commission seeks comment on measures that television broadcasters and other elements of the Canadian broadcasting system can implement to control the loudness of commercial messages relative to adjacent programming. The deadline for the receipt of comments is 18 April 2011.
1. Over the years, the loudness of commercial messages relative to adjacent programming has been the subject of many complaints. This is due, at least in part, to producers’ use of audio processing techniques such as compression to make commercial messages appear to be louder than adjacent programming, even though they are broadcast at the same volume.
2. The perceived loudness of television programming is dependent on a number of factors. These include the nature and content of programming, its peak volume and its dynamic range, among other things. In 2006, based on extensive subjective testing, the International Telecommunications Union (ITU), developed Recommendation ITU-R BS.1770 (the ITU recommendation), which defines an objective means of measuring the perceived loudness of typical audio in a broadcast environment.
3. In November 2009, the Advanced Television Systems Committee (ATSC), which defines international standards for digital television that are used primarily in North America, developed recommended practice A/85 entitled Techniques for Establishing and Maintaining Audio Loudness for Digital Television. This practice builds on the ITU recommendation by defining, among other things, a target loudness level and methods to control the loudness of commercial messages relative to adjacent programming.
4. Other international standard-making bodies have adopted approaches similar to that of the ATSC. The implementation of these approaches in other countries has been accomplished using measures ranging from voluntary initiatives to regulation.
5. Given the recent availability of international standards for measuring and controlling the perceived loudness of commercial messages, the Commission seeks comment on the following questions as they relate to the implementation of the ATSC recommended practice in Canada by television programming undertakings, including conventional television undertakings and specialty services, as well as other elements of the broadcasting system.
To what extent, and by what means, do broadcasters currently control the loudness of commercial messages?
What technical changes are required to implement the recommended practices of the ATSC, and to what extent are broadcasters already planning to implement the associated loudness controls? What are the associated costs and practical implications to broadcasters?
What is the most appropriate timeframe for the implementation of these changes?
What, if any, regulatory changes are required to ensure the effective control of the loudness of commercial messages relative to adjacent programming?
To what extent are related technical and regulatory changes applicable to broadcasting distribution undertakings and video-on-demand programming undertakings, particularly as they relate to local availabilities, refreshed commercial messages or dynamic ad insertion?
Call for comments
6. The Commission invites comments on the questions set out above, and will accept comments that it receives on or before 18 April 2011. The Commission cannot be held responsible for postal delays and will not notify a party whose comment is received after the deadline date. The comment will not be considered by the Commission and will not be part of the public file. Although the Commission is initiating this review using a written process, it may later elect to hold a public hearing on this matter.
7. The Commission will not formally acknowledge comments. It will, however, fully consider all comments, and they will form part of the public record of the proceeding, provided that the procedures for filing set out below have been followed.
