    • A method and apparatus for performing trickplay operations on a multimedia playback device is disclosed. When a trickplay request is received during regular multimedia playback, the appropriate frame for processing at a last processing means is determined in response to the trickplay request. The appropriate frame from a buffer is retrieved using meta data stored in the buffer which identifies the frame and the retrieved frame is processed. Meanwhile, a second appropriate frame in the stored multimedia content is selected for processing by a first processing means in response to the trickplay request. The second appropriate frame and subsequently selected frames are then processed so that the second appropriate frame is available to the last processing means when the last processing means has completed processing of the retrieved frame.
