is extracted from the high resolution one. In the Barbell-lifting coding scheme, a low-
resolution video corresponds to the video down-sampled from a high-resolution one
using a wavelet low-pass filter, specifically the 9/7 filter used in coding. Therefore,
we also use the video down-sampled with a 9/7 wavelet filter as the low-resolution
input in SVC, although it can support arbitrary down-sample filtering. Using the
same down-sampling filter makes it possible to compare the low-resolution recon-
struction qualities of the two schemes in PSNR.
For SVC, the configuration file in JVT-T008 [125] is reused except that the QP ...
