Luma intra mode signaling

A method of coding a picture implemented by a coding apparatus, the method comprising:

• selecting, using the coding apparatus, an intra prediction mode for a current block of the picture;
• encoding, using the coding apparatus, the selected intra prediction mode using truncated binary coding when the selected intra prediction mode is a remaining mode;
• and
• adding the truncated binary code of the selected intra prediction mode to a bitstream of the picture,
• wherein intra prediction modes either belong to a most probable modes (MPM) list or to remaining modes, wherein 6 modes are in the MPM list and 61 modes are in the remaining modes, and wherein the encoding uses 5 bits when the selected intra prediction mode is one of a first three modes from the remaining modes and 6 bits when the intra prediction mode is outside the first three modes.
