Claim Text:
1. A method for video coding using circuitry, comprising: receiving a maximum number of sub-layers for inter-layer prediction plus one, wherein the maximum number of sub-layers for inter-layer prediction plus one indicates whether non-RAP pictures with a layer identifier equal to a layer identifier syntax element value are used as reference pictures for inter-layer prediction; and determining whether a picture of a reference picture layer is marked as “used for long-term reference”; wherein the picture of the reference picture layer is marked as “used for long-term reference” in a case that the maximum number of sub-layers for inter-layer prediction plus one is greater than a value of a temporal identifier for the picture of the reference picture layer, the picture of the reference picture layer is not marked as “used for long-term reference” in a case that the maximum number of sub-layers for inter-layer prediction plus one is not greater than the value of the temporal identifier for the picture of the reference picture layer, and outputting a coded picture including the picture of the reference picture layer which has been, or which has not been, marked as “used for long-term reference”, the coded picture being displayed on a display device.
