Abstract

This invention relates to a method for decoding a video bitstream comprising the steps of: (a) receiving said video bitstream that includes a layer set, where said layer set identifies a plurality of different layers of said bitstream, where at least one of said plurality of different layers includes a plurality of temporal sub-layers; (b) receiving a video parameter set that includes information related to at least one layer of said video bitstream; (c) receiving a video parameter set extension referenced by said video parameter set that includes data regarding said plurality of different layers and said plurality of temporal sub-layers; (d) receiving a video parameter set temporal sub layers information present flag in said video parameter set extension indicating whether said information about plurality of temporal sub-layers are present.

16. :

A method for decoding a video bitstream comprising the steps of;

(a) receiving said video bitstream that includes a plurality of different layers, where at least one of said plurality of different layers includes a plurality of temporal sub-layers; and

(b) decoding a current picture from said bitstream by comparing the maximum number of temporal sub layers of a reference layer for said current picture with a temporal identifier of said current picture and by calculating the number of active reference layers.
