System and method for MPEG reverse play through dynamic assignment of anchor frames
摘要:
A method and system for displaying a series of video frames in reverse order. The video frames are received in groups of pictures (GOPs) from a storage medium. The method comprises steps of (a) decoding and storing a number of frames from an initial GOP into frame buffers according to an ordering of the frame buffers, (b) displaying the stored frames according to the reverse ordering of the frame buffers, (c) decoding and storing a number of frames from a first preceding GOP according to the reverse ordering of the frame buffers, (d) displaying the stored frames according to the ordering of the frame buffers, (e) decoding and storing a number of frames from a second preceding GOP according to the ordering of the frame buffers, and (f) repeating steps (b)-(e),for prior first and second preceding GOPs.
