Abstract
Systems and methods that provide picture-in-picture timebase management are provided. In one example, a method may include the steps of sending a first video signal and a second video signal to a video decoder; sending a first audio signal to the audio decoder, the first audio signal being associated with the first video signal; locking a single timing mechanism to program clock references (PCRs) of the first audio signal; and decoding the first audio signal and the first video signal according to a timebase of the single timing mechanism.
