Reading, UK (November 13, 2007)–Pro-Bel has been presented with the Royal Television Society (RTS) Innovation Award in the Gizmo category for its VALID8 lip-sync test signal generator and receiver. The category recognizes innovation in the form of a discrete piece of hardware that answers a previously unmet need.
Also taken into account is the ease with which the hardware can be assembled, integrated, maintained, understood and used. The RTS citation said of VALID8, “The winning gizmo is something that now offers a unique method of dealing with a thorny issue in complex production and broadcast environments. That particular issue is lip-sync.”
VALID8–Video and Audio Line-up and Identification–addresses problems caused by the increasing complexity of the behind-the-scenes signal processing that is required to ensure that broadcast sound and pictures are delivered to all necessary destinations in all appropriate formats and standards, especially high definition. With a wealth of different concurrent processes frequently being necessary, it is all too easy for sound and pictures to lose synchronization with each other. This causes a gap to appear onscreen that viewers find disturbing, especially when speech is involved, hence the term lip-sync.
Pro-Bel’s VALID8 provides broadcasters with the ability to check at a variety of points in the chain whether video and audio are still in sync. VALID8 clearly and accurately displays precise information about time discrepancies between video and audio signal paths.
The RTS awards were presented on November 6 at Bafta in London.
