Tektronix talks audio-to-video delay at Government Video Exposition 2000

<%=company1%> (Beaverton, OR), a provider of video test, measurement, and monitoring equipment, announced that it will discuss challenges in audio-to-video delay synchronization with government video professionals at the third annual Government Video Technology Exposition. GV Expo is being held at the Washington, D.C. Convention Center on Nov. 29 and 30.

Karl Kuhn, application engineer for Tektronix, will discuss the separation of audio and video processing and inherent delays (commonly known as lip sync) within the video path during the session entitled, Production 2, on Nov. 30 from 12 noon to 1:30pm.

"Audio-to-video delay is not a new problem. However, in today's digital world where video signals get digitized and routed through many layers of processing, opportunities for lip-sync to occur have increased," said Bob Agnes, vice president, Video Business Unit, Tektronix, Inc. "Lip-sync is a quality issue which video professionals can't afford to ignore if they want to keep their audience."

Tektronix will present a means of using digital video watermarking as a way of measuring audio-to-video delay. The Tektronix AVDC100 Audio Video Delay Corrector, recently introduced at IBC2000, is a lip-sync solution that provides automatic correction from program source to final program output using an innovative new application of digital watermarking technology. The in-service device provides broadcasters and network operators with the ability to watermark program video with audio timing information and automatically correct lip-sync errors in real-time during live programming.

Tektronix is a test, measurement, and monitoring company providing measurement solutions to industries including telecommunications, computer, and semiconductor.
