Abstract:
A sampling filter process is provided for scalable video coding. The process provides for re-sampling using video data obtained from an encoder or decoder process of a base layer (BL) in a multi-layer system using adaptive phase shifting to improve quality in Scalable High efficiency Video Coding (SHVC). In order to compensate for phase offsets introduced by downsampling an appropriate phase offset adjustment is made for upsampling in SHVC with an appropriate offset included for proper luma/chroma color space positions. In one approach the luma/chroma phase offset is specified and a filter is selected to apply the appropriate phase change.

Claim (Index 19):
A system for scalable video coding comprising:\n a first coding layer for coding video with a base resolution; a second coding layer for coding video with an enhanced resolution having a higher resolution than the base resolution; an upsampling unit receiving sampling signals from the first coding layer and providing an output signal to the second coding layer after an upsampling process, wherein the upsampling unit output signal enables more efficient coding in the second coding layer, wherein the upsampling unit comprises:\n a first module formed by code executable in a processor for selecting input samples of the video signal in the first coding layer; \n a second module formed by code executable in a processor providing selection of a plurality of filters for processing the selected input samples; and \n a third module including the plurality of filters, the third module formed by code executable in a processor for filtering the selected input samples with the selected filters, the third module providing the output signal from the upsampling unit, wherein one or more phase offsets are decoded in order to select one or more filters used in the upsampling process to provide the output signal from the upsampling unit, and wherein at least one of luma phase offset and chroma phase offset are used to select the one or more filters in the upsampling process, \n wherein the sample location(s) used as input at the first module, are determined using the one or more decoded phase offsets.
