Abstract
Auxiliary data encoded in multimedia content signals synchronizes rendering of different media content types in multimedia content. This auxiliary data includes one or more digital watermarks that are used to synchronize playback of the different media content signals. The digital watermarks identify different media signals, identify rendering locations, such as temporal or spatial areas in a first signal where the media signal is to be rendered, or provide rendering control scripts for controlling playback.
