Abstract
In one embodiment, decoding of a video sigal includes predicting at least a portion of a current image in a current layer based on at least a portion of a base image in a base layer and offset information. The offset information indicates an offset based on at least one pixel in the current image and a corresponding at least one pixel in the base image. For example, the offset information may represent a position offset between at least one sample in the current image and at least one sample in an up-sampled portion of the base image.
Claims21
A method for decoding a video signal, comprising:
- predicting at least a portion of a current image in a current layer based on at least a portion of a base image in a base layer and offset information, the offset information indicating an offset based on at least one pixel in the current image and a corresponding at least one pixel in the base image.
A method of encoding a video signal, comprising:
- encoding at least a portion of a current image in a current layer based on at least a portion of a base image in a base layer, and
- recording offset information in the encoded video signal, the offset information indicating an offset based on at least one pixel in the current image and a corresponding at least one pixel in the base image.
An apparatus for decoding a video signal, comprising:
- a decoder predicting at least a portion of a current image in a current layer based on at least a portion of a base image in a base layer and offset information, the offset information indicating an offset based on at least one pixel in the current image and a corresponding at least one pixel in the base image.
An apparatus for encoding a video signal, comprising:
- an encoder encoding at least a portion of a current image in a current layer based on at least a portion of a base image in a base layer, and recording offset information in the encoded video sigal, the offset information indicating an offset based on at least one pixel in the current image and a corresponding at least one pixel in the base image.
