Inter-layer prediction types in multi-layer video coding

摘要

An apparatus for coding video information according to certain aspects includes computing hardware. The computing hardware is configured to: identify a current picture to be predicted using at least one type of inter layer prediction (ILP), the type of ILP comprising one or more of inter layer motion prediction (ILMP) or inter layer sample prediction (ILSP); and control: (1) a number of pictures that may be resampled and used to predict the current picture using ILMP and (2) a number of pictures that may be resampled and used to predict the current picture using ILSP, wherein the computing hardware is configured to control the number of pictures that may be resampled and used to predict the current picture using ILMP independent of the number of pictures that may be resampled and used to predict the current picture using ILSP.

1. An apparatus configured to code video information, the apparatus comprising:
a memory configured to store video information; and computing hardware operationally coupled to the memory and configured to:
identify a current picture to be predicted using at least one type of inter layer prediction (ILP), the type of ILP comprising one or more of inter layer motion prediction (ILMP) or inter layer sample prediction (ILSP); andcontrol: (1) a first count of pictures resampled and used to predict the current picture using ILMP based on a first maximum count of pictures allowed to be resampled and used to predict the current picture using ILMP and (2) a second count of pictures resampled and used to predict the current picture using ILSP based on a second maximum count of pictures allowed to be resampled and used to predict the current picture using ILSP, wherein the computing hardware is configured to control the first count of pictures resampled and used to predict the current picture using ILMP independently of the second count of pictures resampled and used to predict the current picture using ILSP.
