Abstract

A system and method of synchronizing auxiliary content to a video stream is disclosed that uses a block of bit-vectors linked to a target frame in a video steam. The block of bit-vectors consists of a multi-frame sequence of image bit-vectors. The video stream and block of bit-vectors are transmitted to an end user device that uses the bit-vector block to uniquely identify the target frame. The target frame is used to synchronize auxiliary content to the video stream.
