Motion field upsampling for scalable coding based on high efficiency video coding

摘要

An apparatus for coding video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a first layer having a first spatial resolution and a corresponding second layer having a second spatial resolution, wherein the first spatial resolution is less than the second spatial resolution. The video information includes at least motion field information associated with the first layer. The processor upsamples the motion field information associated with the first layer. The processor further adds an inter-layer reference picture including the upsampled motion field information in association with an upsampled texture picture of the first layer to a reference picture list to be used for inter prediction. The processor may encode or decode the video information.
