1. A decoding method comprising:
performing a first operation or a second operation based on a Network Abstraction Layer (NAL) unit type,
wherein the first operation comprising:
decoding a first picture; and
decoding a second picture after decoding a first parameter set for the second picture, the second picture following the first picture in decoding order, the second picture and the first parameter set for the second picture having a same temporal ID, the temporal ID indicating a hierarchical layer regarding temporal scalability, the NAL unit type of the second picture identical to a NAL unit type of a Step-wise Temporal Sub-layer Access (STSA) picture, and
wherein the second operation comprising:
decoding the first picture; and
decoding a third picture without decoding a second parameter set for the third picture after decoding the first picture, the third picture following the first picture in decoding order, the NAL unit type of the third picture not identical to the NAL unit type of the STSA picture, the third picture having a smaller temporal ID than the second picture.
