ABSTRACT:
The temporal and/or spatial characteristics of a macroblock are analyzed in order to reduce the number of modes for which motion estimation and rate distortion efficiency calculations are to be performed. In one embodiment, macroblock mean and variance characteristics are analyzed to merge sub-blocks together within the macroblock. These merged sub-blocks may be used to identify both inter and intra modes for the macroblock.
