Abstract:
1. A method for decoding a scalable video bitstream, comprising: decoding at least one intra spatial direction mode for intra prediction for at least one sample of a base layer complying with a version of a video coding standard; receiving coded information pertaining to at least one sample of an enhancement layer complying with the same version of the video coding standard, the at least one sample having at least one intra spatial prediction direction mode; and setting at least one Most Probable Mode (MPM) of the at least one sample of the enhancement layer to indicate that the at least one intra spatial prediction direction mode for the at least one sample of the enhancement layer is equal to the at least one intra spatial directional mode for the at least one sample of the base layer; wherein there are no more than three MPMs in the base layer or the enhancement layer; and wherein the method further comprises decoding at least one syntax element S, which indicates whether the at least one intra spatial directional mode for the at least one sample of the enhancement layer is equal to the at least one MPM.
