New Vizio Patent Describes Sensors for Correcting TV Lip Sync Problems

Vizio landed a U.S. patent Tuesday that describes a device and method for “correcting lip sync problems on display devices,” Patent and Trademark Office records show. “Maintaining synchronization” between audio and video on a modern TV “is dependent on a number of variables,” said the patent (9,723,180), which lists Chief Technology Officer Matthew McRae as the inventor, based on a January 2014 application. “The sensor creates timestamps for each of the video and audio, and then calculates a difference between those timestamps.” Those differences are then sent to the external device, “which then compensates for the difference.” Company representatives didn’t comment Tuesday.
