K*WILL is enabling broadcasters to seek out and find the source of lip sync problems wherever they occur. At its NAB2008 booth, the company introduced the portable VP3000, which relies on the company’s Video DNA technology to run signal analysis using double stimulus methodology.
The double stimulus approach compares an original signal source that is presumed to be error free to signal that’s been digitally process, such as a satellite feed or one that’s been encoded or decoded. Based on the original signal, the VP3000 can identify if there’s been any signal degradation, presumably caused by the signal processing. That way, broadcasters have a way to zero-in on the source of the lip syncing errors.
Besides identifying lip sync errors, the new VP3000 can be used as waveform monitor. The product will do video quality monitoring and can small and light enough to be used on a broadcast console or in a satellite truck. A large, bright display allows engineers to step away from the unit and still clearly read the display from a distance as they continue with their work elsewhere.
According to John Alexenko, K*WILL director of sales and technologies, tools like the VP3000 can help the broadcast industry identify the sources of lip sync errors and ultimately allow them to take the steps required to eliminate the audio-video drift that’s plaguing digital television.
