1. A video decoding apparatus for decoding a picture, the video decoding apparatus comprising:
a header decoding circuit that decodes an enabled flag indicating whether a synchronization process for a Context-Adaptive Binary Arithmetic Coding (CABAC) is performed for a first Coding Tree Unit (CTU) of a CTU row, in a parameter set, wherein
the header decoding circuit:
derives a raster scan CTU address list by using a tile position by raster scan of a tile in a slice,
derives a CTU address by using the raster scan CTU address list, and
derives a number of entry points by using the CTU address in a case that a value of the enabled flag is equal to 1.
