Summary:An efficient signaling method for multiple transforms to further improve coding performance is provided. Rather than using code words that are assigned to different transforms in a predetermined and fixed manner, different transform modes are mapped into different code words dynamically. A predetermined procedure is used to assign the code words to the different transform modes. A cost is computed for each candidate transform mode and the transform mode with the smallest cost is chosen as the predicted transform mode, and the chosen predicted transform mode is assigned the shortest code word.
