Claim 15:
16. The decoder of claim 15, wherein in determining whether the current coding block has one transform block or has multiple transform block, the memory comprises instructions that, when executed by the processor, cause the processor to perform operations comprising:
deriving a maximum transform size from decoding elements in the bitstream;
determining whether the width value is less than or equal to a maximum transform size derived from decoding elements in the bitstream and whether the height value is less than or equal to the maximum transform size;
responsive to the width value being less than or equal to the maximum transform size and the height value being less than or equal to the maximum transform size, determining that there is one transform block with a width nTbW equal to the width value and a height nTbH equal to the height value;
responsive to the width value being greater than the maximum transform size and the height value being greater than the maximum transform size, determining that there are multiple transform blocks, each having a width nTbW equal to a minimum of the width value and the maximum transform size and a height nTbH equal to a minimum of the height value and the maximum transform size.
