Abstract:
A method and apparatus related to secondary transform operations. In which, the non-zero transform coefficients in a particular subset of the transform coefficients of the block of pixels is counted and compared with a particular threshold so as to determine whether or not to perform the secondary transform on the block of pixels. Besides, the optimal secondary transform kernel size is derived implicitly based on the size of the block, or derived explicitly based on a flag coded by using an adaptive code word.

Claim (Index 23):
An electronic apparatus comprising:\n a video decoder circuit capable of:\n receiving a bitstream comprising an encoded block of pixels; \n determining a count of non-zero transform coefficients in a particular subset of the transform coefficients of the block of pixels; \n when the count is greater than a particular threshold, decoding the block of pixels by performing non-separable secondary transform (NSST) for the block of pixels; \n when the count is less than the particular threshold, decoding the block of pixels without performing NSST for the block of pixels; and \n outputting the decoded block of pixels.
