METHOD AND SYSTEM FOR DVD SMOOTH REWIND

WIPO Patent Application WO2003046892

A3

Aspects of performing smooth backwards playback in a DVD system are described. The aspects include reconstructing frame data for every frame in a set of frames of an original playback, the set of frames preceding a currently displayed frame. Further included is the utilization of at least seven frame buffers (108) to store frame data during the reconstructing step. The reconstructed frame data is then displayed in reverse order of the original playback for the set of frames. Further aspects include receiving a signal indicating selection of a single frame reverse function. Still further aspects relate to performing smooth search transitions in a DVD system including: calculating an instantaneous frame rate, adjusting a timestamp of a frame based on the calculated instantaneous frame rate, and displaying the frame according to the adjusted timestamp.
