Authors: Kogure, Takuyo; Kihara, Nobuyoshi; Tsuji, Shiro

AES Convention 83 · Paper 2519 · October 1987

Abstract

Digital audio recording is practical on 1/2-in professional M-II format VTRs, and excellent audio, along with high quality video, can be obtained compared with present equipment. In addition, the basic digital audio recording format on M-II can be used for either NISC or PAL. The digital signal processing LSI chip set consists of three devices which are the coding, decoding, and timing circuits. The length of the coding configuration is variable and flexible. At this time, we can produce the actual LSI devices consisting of approximately 3900 gates. These devices include double error correcting capability using a Reed-Solomon code in a very small size.
