Abstract

For the purpose of digital recording of HDTV signals we have designed a bit rate reduction coder that can reduce the input data rate by a compression ratio greater than 2, while maintaining excellent quality for studio applications. In this paper we have developed an adaptive quantization algorithm to decide scale factor that can optimize bit allocation in a cluster unit. Two-layered code data fixed cluster by cluster serves trick play. This algorithm has been designed to fulfil the constraints of professional studio recorders such as interframe editing, multiple copy, picture quality, trick play and robustness for burst and random errors.
