Abstract
In one embodiment of a method of decoding a video signal, at least a portion of a picture in a first picture sequence layer is decoded based on a second picture sequence layer if an indicator in the video signal indicates inter-layer prediction coding.
Claims34
A method of decoding a video signal, comprising:
- decoding at least a portion of a picture in a first picture sequence layer based on a second picture sequence layer if an indicator in the video signal indicates inter-layer prediction coding.
A method of decoding a video signal, comprising:
- decoding at least a portion of a picture in a first picture sequence layer based on at least a portion of a second picture sequence layer base picture in a second picture sequence layer and enhancement layer picture information associated with the second picture sequence layer base picture according to a quality level represented by an indicator in the video signal, the second picture sequence layer base picture having a base level of quality for the second picture sequence layer and the enhancement layer picture information associated with the second picture sequence layer base picture providing information to improve the quality level of the second picture sequence layer base picture.
An apparatus for decoding a video signal, comprising:
- a decoder decoding at least a portion of a picture in a first picture sequence layer based on a second picture sequence layer if an indicator in the video signal indicates inter-layer prediction coding.
A method of encoding a video signal, comprising:
- encoding at least a portion of a picture in a first picture sequence layer based on a second picture sequence layer and setting an indicator in the video signal to indicate inter-layer prediction coding of the picture in the first picture sequence layer.
An apparatus for encoding a video signal, comprising:
- an encoder encoding at least a portion of a picture in a first picture sequence layer based on a second picture sequence layer and setting an indicator in the video signal to indicate inter-layer prediction coding of the picture in the first picture sequence layer.
A bitstream representing a video signal having a data structure, comprising:
- a first stream portion representing at least a portion of a picture in a first picture sequence layer encoded based on a second picture sequence layer and including an indicator to indicate inter-layer prediction coding of the picture in the first picture sequence layer.
