摘要
The present invention is a method to accelerate the frame/field decision by estimating more suitable structure using SAD (sum of absolute difference) between picture samples and their mean. Next the uses the correlation observed between the optimal macroblock prediction modes found with the inferred structure and the probability of the non-inferred structure being better than the inferred one. The invention can lead to the significant reduction of the computational complexity at the cost of slight degradation of coding efficiency.
