Abstract
A system and method for synchronizing audio from a program source with closed captioning data includes a caption encoder having a video-audio delay line. The caption encoder with the delay line is adapted to delay the programming source by a settable amount of time so that the program audio can be synchronized with closed caption data received from a remote live captioner.
