A METHOD AND SYSTEM FOR DETERMINING INTRA MODE DECISION IN H.264 VIDEO CODING

摘要

The present disclosure provides a method and a system for determining a prediction mode for performing intra prediction of a plurality of frames of a digital video in H.264 video coding format. The method and system include a determination module to determine a 16X16 prediction mode from a first set of plurality of prediction modes for each of intra 16X16 macroblock utilizing a first pre-defined criteria and decide a 4X4 prediction mode from a second set of plurality of prediction modes for each of intra 4X4 sub-macroblock utilizing a second pre-defined criteria, a comparison module to compare computational cost of the 16X16 prediction mode and the 4X4 prediction mode and a declaration module to declare one of the 16X16 prediction mode and the 4X4 prediction mode as the prediction mode for each of the macroblock based on the compared computational cost.
