Abstract:
1. 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.
