Abstract
This paper proposes a unique motion estimation and motion compensation (ME/MC) hardware architecture for a scene- adaptive algorithm. The most significant feature is the independence of the two modules for the ME/MC. This enables the encoder to analyze the statistics of a scene before encoding it and to control the whole encoding process adaptively according to the scene. The scene-adaptive controls involve changing various encoding parameters, such as the search area or selection criteria, in the slice cycle or even in the macroblock cycle. The search area of our ME/MC architecture is plus or minus 211.5 horizontally and plus or minus 113.5 vertically by the area hopping method. The architecture is loaded on a single-chip MPEG2 MPML encoder.
