1. A coding apparatus, comprising:
a memory storing instructions; and
one or more processors coupled to the memory, the one or more processors configured to execute the instructions to cause the coding apparatus to:
select an intra prediction mode for a current block; and
encode the selected intra prediction mode using truncated binary coding every time the selected intra prediction mode is a remaining mode, wherein the encoding the selected intra prediction mode comprises using N bits when the selected intra prediction mode is included in a first portion from remaining modes and using N+1 bits when the selected intra prediction mode is included in a second portion of the remaining modes.
