I wonder if Neil Brydon was funny. He's talking to Broadcasters about video manipulation:-)................ Digital Video Handling Comes Into Focus By Joe Fedele, TV TECHNOLOGY From cable to fiber to storage systems, "The Foundations of DTV - The Physical Plant" took an in-depth look at how digital video is routed and managed throughout broadcast facilities. Moderated by Jerry Whitaker of Technical Press, the afternoon of tutorials answered many questions about how best to handle digital signals. TECHNICAL CHARACTERISTICS The program began with Stephen Lampen of Belden Electronics talking about "Transporting Video Signals on UTP Category 5" and how Cat-5 cabling can be used in lieu of the standard coaxial cable traditionally used in broadcasting and production environments. Lampen's review and analysis of the technical characteristics of each type of cable provided insight into some alternative methods of wiring a technical facility. Neil Brydon of DiviCom was the next speaker with "How Many Bits Can You Afford to Waste?" His discussion focused on compression, noise and bit rate reduction. Brydon's review of the fundamentals of noise reduction, preprocessing and quantization set the stage for a discussion about removing unwanted noise through the use of temporal filters. "Temporal filtering is effective against random noise," he said. "The key is to eliminate the temporal mechanism that causes the motion blurring effect." He then went on to show how this might be accomplished. Peter Symes of the Grass Valley Group addressed several Master Control-related issues that broadcasters face with multichannel DTV operations. Symes also identified the need for flexibility in Master Control operations and talked about switching problems in an MPEG encoded environment. In his tutorial "Designing and Building the Digital Studio," Daniel Taylor of DTA Carlson, revisited several projects discussed at last year's conference and reviewed the progress made since then. more......................... nab.org
