Master System of Digital Terrestrial Broadcasting

摘要

Following the introduction of broadcast satellite (BS) digital broadcasting in December 2000, digital terrestrial broadcasting services commenced in Japan in December 2003. In order to realize these new services, the various types of studio equipment used in the broadcasting system were required to provide higher compression, higher picture quality, multichannel functionality, and smaller size compared with those for BS digital broadcasting. This paper introduces a switcher, an MPEG-2 encoder, and a multiplexer newly developed by Toshiba to meet these requirements.
