Abstract:
An image encoding method includes: determining whether a current picture is a TSA picture or a trailing picture; and encoding a plurality of pictures according to whether the current picture is the TSA picture or a trailing picture. The determining includes: determining the current picture to be the TSA picture when the current picture does not belong to the highest layer and corresponds to a first field, and determining the current picture to be the trailing picture when the current picture belongs to the highest layer or corresponds to a second field.

Claim (Index 2):
An image decoding method for decoding, on a per field basis, a plurality of pictures classified into a plurality of layers for which reference from a picture belonging to a higher layer to a picture belonging to a lower layer is prohibited, the plurality of pictures including at least one picture that is decoded as a temporal sub-layer access (TSA) picture for which predetermined reference is prohibited, the image decoding method comprising:\n identifying whether a current picture included in the plurality of pictures is the TSA picture; decoding the plurality of pictures according to whether the current picture is the TSA picture; and decoding a picture type indicating whether a current picture included in the plurality of pictures is the TSA picture; wherein the identifying includes identifying the current picture as the TSA picture according to the decoded picture type when the current picture does not belong to a highest layer in the plurality of layers and corresponds to a first field that is decoded earlier than a second field in a pair of fields in a frame.
