Inter-layer reference picture generation for hls-only scalable video coding

A method of coding video information, the method comprising:

• resampling video information of a reference picture of a picture to be encoded to obtain a resampled picture, the reference picture having a plurality of slices and having a different picture size than the picture to be encoded;
• determining slice definitions for a plurality of resampled slices in the resampled picture, the plurality of slices of the resampled picture corresponding to a plurality of slices of the reference picture;
• determining, 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;
• and
• in 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, modifying 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 scan rule to satisfy the at least one slice definition rule.

Non-transitory computer-readable storage media having instructions stored thereon that when executed cause an apparatus comprising at least one processor 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;
• and
• in 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 to satisfy the slice definition rule.

An apparatus configured to code video information, the apparatus comprising:

• means for storing video information associated with a picture;
• means for resampling video information of the picture to obtain a resampled picture, the picture having a plurality of slices;
• means for determining slice definitions for a plurality of slices of the resampled picture, the plurality of slices of the resampled picture corresponding to the plurality of slices of the picture;
• means for determining, 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;
• and
• means for modifying the slice definition for at least some of the plurality of slices of the resampled picture in response to determining that at least one of the plurality of slices of the resampled picture does not satisfy at least one of the one or more slice definition rules.
