Abstract:
Methods, systems, and computer program products for the generation of multiple layers of scaled encoded video data compatible with the HEVC standard. Residue from prediction processing may be transformed into coefficients in the frequency domain. The coefficients may then be sampled to create a layer of encoded data. The coefficients may be sampled in different ways to create multiple respective layers. The layers may then be multiplexed and sent to a decoder. There, one or more of the layers may be chosen. The choice of certain layer(s) may be dependent on the desired attributes of the resulting video. A certain level of video quality, frame rate, resolution, and/or bit depth may be desired, for example. The coefficients in the chosen layers may then be assembled to create a version of the residue to be used in video decoding.

Claim (Index 36):
A method of scalable video coding (SVC), comprising:\n receiving a multiplexed bitstream comprising multiple layers of encoded video data; decoding the multiplexed bitstream, wherein the decoding includes selecting from the multiplexed bitstream a subset of the layers; deriving from the layers a sampled subset of coefficients that are within a sample range and satisfy different predetermined sampling patterns comprising a sampling period and a sampling phase, wherein the phase specifies one or more coefficients within the sampling period that are included in each of the sampled subsets of the coefficients; assembling the sampled subsets of coefficients into a coefficient matrix that represents, at least in part, residue of an SVC compression process; and performing an inverse transform on the coefficient matrix, to create a version of the residue.
