1. A decoding method, comprising:
acquiring information about a target picture from a bitstream; and
performing decoding on the target picture using the information about the target picture,
wherein the decoding comprises a determination of a reference picture list for the target picture, and
wherein the information about the target picture includes a slice header for a slice of the target picture,
the bitstream includes first information,
the first information indicates whether reference picture list syntax elements can be present in slice headers of slices with a NAL unit type equal to a specific type,
the reference picture list is configured for the target picture in a case that the first information indicates that the reference picture list syntax elements can be present in the slice headers of the slices with a NAL unit type equal to the specific type,
the decoding comprises a determination of whether an override on the number of activated reference indexes in the slice header is to be performed or not, and
the determination of whether the override is to be performed is performed regardless of a value of the first information.
