Abstract
Disclosed herein are video coding techniques for prediction of a to-be-reconstructed block from enhancement layer/view data from base layer/view data in conjunction with enhancement layer/view data, where samples that are not available in the base or enhancement layer/view, respectively, are being predicted through padding.
Claims24
A method for video decoding, comprising:
- decoding a first picture of a reference layer including first header information pertaining to the first picture, wherein the first header information comprises dimensions of the first picture;
- decoding second header information of a second picture of an enhancement layer or view, wherein the second header information comprises the dimensions of the second picture;
- decoding at least one offset indicative of the relative position of at least one sample of the second picture relative to its reference sample position in the first picture;
- determining a sample location in the first picture using at least two of the first picture's dimensions, the second picture's dimensions, and at least one of the at least one offsets;
- identifying at least one unavailable sample position in the first picture for which the corresponding sample location for the second picture is not within the first picture's picture dimensions;
- inferring at least one property of the sample in the at least one unavailable sample position;
- and
- decoding the second picture utilizing the at least one property of the sample in the at least one unavailable sample position for inter-layer prediction.

A non-transitory computer readable medium comprising a set of executable instructions to direct a processor to:
- decode a first picture of a reference layer including first header information pertaining to the first picture, wherein the first header information comprises dimensions of the first picture;
- decode second header information of a second picture of an enhancement layer or view, wherein the second header information comprises the dimensions of the second picture;
- decode at least one offset indicative of the relative position of at least one sample of the second picture relative to its reference sample position in the first picture;
- determine a sample location in the first picture using at least two of the first picture's dimensions, the second picture's dimensions, and at least one of the at least one offsets;
- identify at least one unavailable sample position in the first picture for which the corresponding sample location for the second picture is not within the first picture's picture dimensions;
- infer at least one property of the sample in the at least one unavailable sample position;
- and
- decode the second picture utilizing the at least one property of the sample in the at least one unavailable sample position for inter-layer prediction.

A system for video decoding, comprising:
- a processor;
- and
- a non-transitory computer readable medium embodying software that is configured when executed by the processor to:
- decode a first picture of a reference layer including first header information pertaining to the first picture, wherein the first header information comprises dimensions of the first picture;
- decode second header information of a second picture of an enhancement layer or view, wherein the second header information comprises the dimensions of the second picture;
- decode at least one offset indicative of the relative position of at least one sample of the second picture relative to its reference sample position in the first picture;
- determine a sample location in the first picture using at least two of the first picture's dimensions, the second picture's dimensions, and at least one of the at least one offsets;
- identify at least one unavailable sample position in the first picture for which the corresponding sample location for the second picture is not within the first picture's picture dimensions;
- infer at least one property of the sample in the at least one unavailable sample position;
- and
- decode the second picture utilizing the at least one property of the sample in the at least one unavailable sample position for inter-layer prediction.
