Abstract
A portion of the number of bits initially allocated for encoding some of the frames of a group of pictures (GOP) is accumulated in a bit bank and is subsequently used to encode other frames that may require a larger number of bits to encode than those initially allocated for these frames. Furthermore, when a scene change P frame is detected in a first GOP, a second GOP is formed. The second GOP includes the scene change P frame as well as the remaining unencoded frames of the original GOP. The P frame of the first GOP is changed to an I frame in the second GOP. Furthermore, the frame to be displayed after the I frame of the second GOP is also changed to a duplicate of the I frame of the second GOP.
