MOTION DERIVATION AND CODING FOR SCALING VIDEO

摘要

A system utilizing motion derivation and coding for scaling video is described. The system may include an electronic device configured to receive a first layer bitstream and a second enhancement layer bitstream corresponding to the first layer bitstream. The electronic device may be configured to derive a motion vector at the second layer representation from the first layer representation.

1. A system, comprising:
an electronic device of a decoder, the electronic device configured to: receive a first layer bitstream; receive a second enhancement layer bitstream corresponding to the first layer bitstream; wherein the second enhancement layer bitstream is dependent on the first layer bitstream; determine whether a motion vector infer information in the second enhancement layer bitstream corresponds to a predetermined value; in response to determining that the motion vector infer information in the second enhancement layer bitstream does not correspond to the predetermined value, performing first operations including decoding a current prediction unit of the second enhancement layer bitstream using a motion vector derived from a motion vector of the first layer bitstream; and in response to determining that the motion vector infer information in the second enhancement layer bitstream does correspond to said predetermined value, performing second operations including constructing a motion vector predictor list derived from the second enhancement layer bitstream and use the motion vector predictor list for the current prediction unit of the second enhancement layer bitstream.
