Estimating the term…
Methods, apparatus, and systems for video coding/decoding are disclosed. One representative method includes a decoder receiving video content including at least a base layer (BL), an enhancement layer (EL) and phase information. The phase information includes an indicator indicating one or more sets of phase parameters from among plural sets of phase parameters. The method further includes assembling the BL into an inter-layer reference (ILR) picture based on the video content and the received phase information, selecting one or both of the ILR picture or an EL reference picture, and predicting a current EL picture using the phase information and one or more of the selected ILR picture or the selected EL reference picture.
A video decoder apparatus for use in decoding video data comprising a processor configured to receive a video signal including base layer video content comprising interlaced field pictures and enhancement layer video content comprising progressive frame pictures, store one or more sets of cross layer phase alignment parameters for use in resampling a video picture, assemble one or more progressive frame inter-layer reference (ILR) pictures for use in predicting at least one progressive frame picture in the enhancement layer based on a field picture in the base layer and one or more of the sets of stored cross layer phase alignment parameters, and predict an enhancement layer picture using the ILR picture.
A video encoder apparatus for encoding video data comprising a processor configured to transmit a video signal including base layer video content comprising interlaced field pictures and enhancement layer video content comprising progressive frame pictures, and transmit one or more sets of cross layer phase alignment parameters for use in resampling a video picture in the base layer for use by a video decoder in assembling one or more progressive frame inter-layer reference (ILR) pictures for predicting at least one progressive frame picture in the enhancement layer based on a field picture in the base layer and one or more of the sets of cross layer phase alignment parameters.
