INTER-LAYER REFERENCE PICTURE GENERATION FOR HLS-ONLY SCALABLE VIDEO CODING

摘要

An apparatus for coding video information may include a memory unit configured to store video information associated with a picture and a processor in communication with the memory unit configured to resample video information of a reference picture to obtain a resampled picture having a plurality of slices and a different picture size than a picture to be encoded. Further, the processor may determine slice definitions for slices in the resampled picture. The slices of the resampled picture may correspond to slices of the reference picture. The processor may determine, based on the slice definitions, whether a slice of the resampled picture satisfies one or more slice definition rules. In response to determining that the slice of the resampled picture does not satisfy at least one slice definition rule, the processor can modify the slice definition for the slice so as to satisfy the slice definition rule.

1. An apparatus for coding video information, the apparatus comprising:
a memory unit configured to store video information associated with a picture; a processor in communication with the memory unit, wherein the processor is configured to:
resample video information of a reference picture to obtain a resampled picture, the reference picture having a plurality of slices and having a different picture size than a picture to be encoded;determine slice definitions for a plurality of slices in the resampled picture, the plurality of slices of the resampled picture corresponding to a plurality of slices of the reference picture;determine, based at least partially on the slice definitions, whether each of the plurality of slices of the resampled picture satisfies one or more slice definition rules; andin response to determining that at least one of the plurality of slices of the resampled picture does not satisfy at least one slice definition rule, modify the slice definition for at least some of the plurality of slices in the resampled picture that do not satisfy the at least one slice definition rule so as to satisfy the slice definition rule.
