TL;DR: In this article, MI was used to improve residue prediction by using MI even when the base layer MB is encoded in intra mode such as copying intra4x4 mode of one 4x4 block to multiple neighboring 4x 4 blocks in the enhancement layer.

- 12 Jan 2006
TL;DR: In this article, a flag bit is coded to indicate which predictive motion vector is chosen only if it is not possible to infer the layer from which the predicted motion vector for the current block comes, such as when both predictive motion vectors are substantially the same, or only one of the vectors is reliable or available.

- 12 Jan 2006
TL;DR: A scalable video coding method and apparatus for coding a video sequence, wherein the coefficients in the enhancement layer is classified as belonging to a significant pass when the corresponding coefficient in the base layer is zero, and classified as belong to a refinement pass when a corresponding coefficient is non-zero as mentioned in this paper.

TL;DR: In this paper, the coefficients of independent spatial transforms can be arranged into subbands and the encoding of the subbands can utilize spatial information and coded block flags and end of block flags to reduce bit rate.
