Aspects of Digital HDTV Coding

Gordon M. Drury, Alois M. Bock

Practical high-definition television (HDTV) broadcasting has been an objective for television engineers for decades and is now feasible through the use of the MPEG-2 compression algorithm. The source bit rate can exceed 1 Gbit/sec and the target rate for transmission is less than 20 Mbits/sec thus requiring a reduction ratio of more than 60:1. Implementing MPEG-2 for HDTV is a significant technical challenge because the processing speeds involved are high and particularly affect the motion estimation and compensation part of the process. This paper is concerned with how implementation issues affect the performance of MPEG-2 coding for HDTV.
