Abstract:
1. A method of decoding a scalable video coded bitstream comprising: receiving the scalable video coded bitstream including a quality base layer and an enhanced layer; checking restriction flag information for specifying a presence of a specific syntax for codec compatibility; obtaining first identification information from the scalable video coded bitstream based on the restriction flag information, the first identification information indicating whether to store a quality base picture as a reference picture in a buffer; checking reference identification information specifying whether or not the quality base picture is used as a reference base picture; marking the quality base picture as the reference picture and as a reference base picture when the reference base picture is stored according to the first identification information, the reference base picture being used for identifying the quality base picture, wherein the quality base picture is marked as the reference base picture when the reference identification information indicates the quality base picture is used as the reference base picture, and the first identification information indicates to store the quality base picture as the reference picture; and decoding an enhanced picture of the enhanced layer using the quality base picture marked as the reference picture and the reference base picture.
