METHOD AND APPARATUS FOR DETERMINING ENCODING MODE BASED ON TEMPORAL AND SPATIAL COMPLEXITY

摘要

A method and apparatus for deciding an encoding mode are disclosed. The encoding mode decision apparatus comprises a temporal complexity calculator to calculate a temporal complexity of a macroblock and a mode decider to elect the encoding mode utilizing the temporal complexity. The disclosure calculates the temporal and spatial complexes for the macroblocks more accurately as well as elects the optimal encoding mode using the same resulting in a reduction of the calculation complexity when applying the rate-distortion technique along with an improvement of its processing speed.
