Automatic analysis system of TV commercial emission level

The purpose of the study was to determine whether the level of commercial emission is higher than the level of regular program and to check if the commercials broadcasters follow the recommended levels of loudness. The paper shortly reviews some chosen methods of volume measurements specified in the ITU and EBU recommendations. Then, it describes a prototype of a system implemented in Embarcadero C++ Builder 2010 which carries out automatic evaluation of loudness using the recordings acquired directly from TV programs. In the end, the results of the measurements obtained for TV commercials are shown, and the conclusions are drawn. The final Section outlines also future work being planned.
