Abstract:
1. A video coding method comprising: (a) a step of obtaining at least two bandwidth values; (b) a step of coding a reference layer to create coded reference layer data, such that a rate of the coded reference layer data is less than or equal to a lowest bandwidth of the at least two bandwidth values; (c) a step of separating the reference layer into a first subset of data serving as a reference for an interlayer prediction of an enhancement layer, and a second subset of data that is not used for the interlayer prediction of the enhancement layer, each subset of data comprising less data than that of the entire reference layer, wherein, during said step of separating the reference layer: (d) at least one step of coding, for at least a first bandwidth greater than the lowest bandwidth, the enhancement layer to create a coded enhancement layer, such that a sum of a rate of data of the coded enhancement layer and a rate of the first subset of data is less than the first bandwidth greater than the lowest bandwidth.
