Abstract:
A video decoding method, comprising, from a stream of coded video data:identifying data of a coded video object based on a start code indicative thereof, identifying data of a plurality of coded video object layers (VOLs) based on respective VOL start codes, identifying data of a plurality of coded video object planes (VOPs) based on respective VOP start codes, each coded VOP being a member of at most one VOL, determining, from data of a first VOL: whether scalability had been applied to the first VOL at coding, and if scalability had been applied, identifying from the coded data of the first VOL data a second VOL that is a reference layer to the first VOL, and decoding a VOP from the first VOL with reference to a VOP of the second video object layer.
