19 Claims

1. A device, comprising:

a receiver, configured to receive a bitstream; and

at least one storage medium configured to store the bitstream;

wherein the bitstream comprises:

indication information of a current block, a value of the indication information indicating whether an intra prediction mode of the current block is included in a set of most probable modes; and

a syntax element representing a remainder intra prediction mode when the value of the indication information indicates the intra prediction mode of the current block is not included in the set of most probable modes;

wherein the intra prediction mode of the current block is derived by:

setting the intra prediction mode equal to the syntax element, and incrementing a value of the intra prediction mode by one; and

for each candidate intra prediction mode candModeList[i] in an array of candidate intra prediction modes, when the intra prediction mode is greater than candModeList[i], incrementing a value of the intra prediction mode by one, wherein candModeList[i] represents a candidate intra prediction mode in the set of most probable modes, and wherein i ranges from N to M, inclusive, N and M are natural number, N>M.
