In developing high speed digital video decoder systems such as MPEG I,
II, Multimedia decoder or high-definition TV (HDTV), it is essential
to have a real time data stream generation apparatus. In this paper, a
real time bit stream generator using conventional SCSI-II type harddi
sc is proposed and implemented, and its effectiveness is verified in d
eveloping the prototype HDTV decoder system. The design concept and im
plementation are described. The bit stream generator and HDTV decoder
had been successfully demonstrated during the '93 EXPO in Taejon KOREA
.
