Abstract :
Radio and television broadcasters increasingly encounter the problem of loudness in broadcast programmes. The problem occurs at all stages beginning with the production of a programme, ending with the transmission. In order to meet the expectations of broadcasters and receivers of radio and television content the International Telecommunication Union (ITU) has developed an algorithm for measuring the loudness of programmes simultaneously introducing a measurement unit for loudness, LU In the paper the influence of bitrate on the loudness measured in the audio stream of TV programmes has been presented.
