Abstract:

This paper provides a summary of BBM Canada's picture matching experience over the last four years. The authors focus on how well picture matching compares with DFM, how multimatching is handled, the problem of unmatched viewing, picture matching's ability to handle various delivery systems, and the extent to which picture matching can handle viewer behaviours like fast channel changing and channel surfing. The results of the assessment after four years indicate that picture matching is handling a very complex TV environment quite well. However, there are points for discussion including other uses for the TV that might need to be measured, the degree of granularity in measurement that is acceptable, and, of course, the issue of sample size.
