Abstract :
This paper proposes a new rate control scheme for an MPEG-2 HDTV parallel encoding system consisting of multiple encoding units. In this rate control scheme, the target number of bits is allocated to each encoding unit every frame period using the complexity of the divided parts of an image. We evaluate this rate control scheme and verify that its image quality is as good or better than that of single encoding
