- Abstract
- Professional broadcasting applications of digital processing technology have been proceeding well for the last decade. The agreement of the fundamental standard for the so-called “4:2:2” studio signal coding—ITU-R Recommendation 601—began a continuing process of development within studios and in contribution and distribution. During the late 1980s, high-performance video and audio compression systems based on the 4:2:2 standard were developed for use in contribution and distribution. Some of these were standardized by ITU-T and in Europe by the European Telecommunication Standards Institute (ETSI). These systems were based on high bit rates, typically 140 Mbits/sec or 34 to 45 Mbytes/sec, required by the compression algorithms available at the time. Technology has moved on, and the MPEG standard can achieve remarkable results at lower bit rates, typically in the range of 5 to 20 Mbits/sec, which is sufficient to support the needs of contribution and distribution applications.

bio
Alois Bock received his degree from the Fachhochschule Konstanz in Germany in 1985 and a Ph.D. from Coventry Polytechnic in 1988. Bock, a principal engineer with NDS working on MPEG-2 encoding algorithms, has been involved in various aspects of MPEG compression encoding, in particular the design of motion estimation circuits and noise reduction algorithms. He is a member of IEE.G. M. DruryNDS Broadcast, Eastleigh, Hampshire 8050 9NW, U.K.bio
G. M. Drury began his career in 1967 working in R&D for telecommunications, including early compression systems for television. In 1995 he was appointed Vice-President, Technology, at NDS, where he is responsible for research into new technology, standardization, and for the management of patents and licensing activities. Drury is a Fellow of the UK Institution of Electrical Engineers.W. J. HobsonNDS Broadcast, Eastleigh, Hampshire 8050 9NW, U.K.bio
Warren Hobson graduated from Southampton University with a B. Sc. degree in 1986. He is now working for News Digital Systems (NDS) at their engineering headquarters, based in Southampton, U.K. At NDS he manages the engineering team developing MPEG-2 transmission products to spearhead the transition of the broadcasting industry from analog to digital TV. - Copyright
