Abstract:
1. A method for encoding video content into a temporal layered coding structure comprising: defining a plurality of sub-sequence layers in a layer hierarchy; selectively assigning each of a plurality of images within a sub-sequence of a group of images to a respective one of said sub-sequence layers such that a grouping of images contained in any sequential combination of sub-sequence layers that includes a hierarchically lowest of said sub-sequence layers results in a group of images that temporally are substantially evenly spaced; wherein intra images (I-images) are exclusively assigned to said hierarchically lowest sub-sequence layer, predictive images (P-images) are assigned to a second of said sub-sequence layers, said second sub-sequence layer being one level higher than said lowest sub-sequence layer in said layer hierarchy and a selected first set of B
