Abstract:
1. A video coding method comprising: decoding a fine granularity scalability (FGS) base layer to reconstruct a base layer video block defining video at a first spatial resolution; at least partially decoding one or more FGS enhancement layers to reconstruct an enhancement layer video block defining video at a second spatial resolution greater than the first spatial resolution; upsampling the reconstructed base layer video block to the second spatial resolution to form an upsampled base layer video block comprising a first prediction block for a current intra-coded video block of one of the FGS enhancement layers, wherein the first prediction block comprises an interpolated pixel resulting from the upsampling; forming a second prediction block from pixels in the enhancement layer video block that neighbor the current intra-coded video block in the one of the FGS enhancement layers, wherein the second prediction block comprises a pixel collocated with the interpolated pixel of the first prediction block; and predicting the current intra-coded video block based on a weighted sum of the first prediction block and the second prediction block, wherein predicting the current intra-coded video block comprises:
