Description

BS digital broadcasting has been started since December 2000. The four frequencies were newly allocated to Japan in addition to the currently used eight frequencies for the BS broadcasting. Broadcasting via a communication satellite at 110 degrees of east longitude has been standardized in the same technical specifications as the BS digital broadcasting. The standardization of terrestrial broadcasting has been completed, and its broadcasting is just prepared on business. In this background, aiming the realization of digital HDTV broadcasting at the lower bitrates, we are studying the improvements on the coding algorithms at the encoder without changing the current MPEG-2 receivers. In this study, we have started research on a pre-filtering. This paper describes the structure of this hardware.
