Abstract:
1. An apparatus comprising: an input interface, coupled to receive an input image, the input image comprising of a plurality of macroblock pairs, each of the plurality of macroblock pairs including a first macroblock and a second macroblock that are adjacent to each other, each macroblock comprising a top field including all even lines and a bottom field including all odd lines; a first preprocessor circuit configured to generate a plurality of field decision indicator values, at least one of the plurality of field decision indicator values is associated with each of the top field in the first macroblock, the bottom field in the first macroblock, the top field in the second macroblock and the bottom field in the second macroblock, each of the plurality of field decision indicator values being based upon a plurality of macroblock-based feature statistics for the corresponding field; a memory configured to store the plurality of field decision indicator values for each of the plurality of macroblock pairs; and a second preprocessor circuit configured to generate a macroblock pair coding decision value for each of the plurality of macroblock pairs based upon a combination of the plurality of field decision indicator values, the macroblock pair coding decision value indicating a macroblock frame and field coding decision.
