ABSTRACT:
A method of encoding flags, a method of decoding flags and an apparatus thereof, in which flag encoding and decoding can be efficiently performed by using spatial correlation between various flags included a plurality of blocks are provided. The method includes collecting flag values respectively allocated to groups of the plurality of blocks according to spatial correlation of blocks to create a flag bit-string, dividing the flag bit-string into a plurality of divided bit-strings using a group size, setting a pattern bit indicating whether all bits included in the divided bit-strings are 0 or not, and performing entropy coding on the divided bit-strings according to the set pattern bit.
