Abstract
The dynamic range of the loudness after digitalization of television broadcasting is enlarged, and the loudness difference between the broadcast channel and between the programs within the same channel is expanded. This was subjected to interfere with the television viewer's comfort. In order to improve these problems international standards for the loudness normalization was established in ITU, Europe, USA and Japan. This regulation was introduced to Korea also as technical regulation, and this will apply the broadcast service in June 2016. In this paper, ahead of the introduction of digital television technology based on loudness measurement for the major television channel and to present the results of the comparison of technical standard.
