13. A system for decoding video encoded in a base view and at least one enhancement view and having at least a difference mode and pixel mode, comprising:
-
a base layer decoding device for creating at least one sample of a reconstructed picture; an upsample module coupled to the base layer decoding device, for at least one of upsampling and disparity compensation predicting the at least one sample of a reconstructed picture to an enhancement view resolution; and an enhancement view decoding device coupled to the upsample module, the enhancement view decoding device being configured to decode at least one flag bDiff from an enhancement view bitstream, decode at least one enhancement layer sample in the difference mode or the pixel mode selected by the flag bDiff, receive at least one upsampled reconstructed base view sample for use in reconstructing the enhancement view sample when operating in difference mode as indicated by the flag bDiff.
