摘要

针对由多个编码单元组成的MPEG-2 HDTV并行编码系统，提出了一种新的速率控制方案。在这种速率控制方案中，利用图像分割部分的复杂度，在每帧周期为每个编码单元分配目标位数。我们对这种速率控制方案进行了评估，并验证了其图像质量与单一编码一样好或更好。

Global rate control scheme for MPEG-2 HDTV parallel encoding system

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.
