Method and Apparatus for Manipulating MPEG Video

摘要

A computer implemented method of manipulating and displaying an MPEG stream is described. In one embodiment of the invention, a computer implemented method comprises defining a spatial location across a series of pictures of an MPEG stream; and for each picture of the series of pictures in the MPEG stream, partially decoding the picture to determine an area of the picture falling within the spatial location.
