alable layer with a layer identifier equal to any value of layer_id[ present in the layer dependency change SEI message, the layer dependency relationship is changed for the target access unit set relative to the layer dependency relationship specified by the most recent scalability information SEI message in decoding order. For a scalable layer with a layer identifier not equal to any value of layer id| i ] present in the layer dependency change SEI message, the layer dependency relationship remains the same as the one specified in the most recent scalability information SEI message in decoding order. When, according to the layer dependency information indicated in the most recent scalability information SEI message in decoding order, a scalable layer A does not directly or indirectly depend on another scalable layer B, the layer dependency change SEI message shall not specify that the scalable layer A directly or indirectly depends on the scalable layer B. When a scalable layer is considered to directly or indirectly depend on another scalable layer is specified in clause G.13.2.1, with the target access unit set being the target access unit set for the layer dependency change SEI message. num_layers_minus1 plus 1 specifies the number of scalable layers for which a layer dependency information change relative to the most recent scalability information SEI message, in decoding order, is indicated in the layer dependency change SEI message. The value num_layers_minusl is in the range of 0 to 2047, inclusive. layer_id[i] indicates the layer identifier of the scalable layer for which a layer dependency information change is indicated by the following syntax elements. The value of layer_id[i] shall be in the range of 0 to 2047, inclusive. The value of layer_id[ shall be equal to one of the values of layer_id[i in the most recent scalability information SEI message. When i is greater than 0, the value of layer_id[ shall not be equal to any of the values of layer_id[ with j=0..(i-1). NOTE 2 - When an application remov
