1. A video decoding apparatus, comprising:
a parsing module configured to:
parse a slice header of a second picture that is a next picture of a decoded first picture; wherein the slice header of the second picture includes reference picture information indicating whether the decoded first picture is a reference picture,
mark the decoded first picture as a reference picture in a Decoded Picture Buffer (DPB),
determine whether the decoded first picture is a non-reference picture based on the reference picture information included in the slice header of the second picture,
mark the decoded first picture marked as a reference picture as a non-reference picture when the decoded first picture is a non-reference picture, and
parse a transmission unit header of a transmission unit for the first picture,
wherein the transmission unit header does not comprise flag information indicating whether the transmission unit for the first picture is a non-reference picture or a reference picture, and
wherein the transmission unit header comprises type information of the transmission unit.
