LSIによるPx64標準ビデオコーデック : 情報入力

抄録

A p x 64 kbit/s standard video codec for videophone and videoconferencing applications has been developed, conforming to CCITT Recommendations related to audiovisual teleservices. This paper describes hardware implementation after a comparison between two promising design methods i.e. DSP-based and LSI-based implementation. As a result of the comparison, LSI-based implementation has turned out to be more advantageous for videoconferencing codecs. By optimum partitioning of codec functions, a new chip set is developed, resulting in a small-sized codec.
