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