Abstract:
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.

Claim (Index 15):
An electronic apparatus comprising:\n a video decoder circuit capable of:\n receiving transform coefficients that are encoded by using a target transform mode that is selected from a plurality of candidate transform modes; \n computing a cost for each candidate transform mode and identifying a lowest cost candidate transform mode as a predicted transform mode; \n assigning code words of varying lengths to the plurality of candidate transform modes according to an ordering of the plurality of the transform modes, wherein the predicted transform mode is assigned a shortest code word; \n parsing a code word from a bitstream and matching the parsed code word with the code words assigned to the plurality of candidate transforms to identify the target transform mode; \n decoding the block of pixels by using the identified target transform mode; and \n outputting the decoded block of pixels.
