 for output. NOTE 12 - The decoding result for a scalable layer representation with layer_output_flag[ equal to 0 may be inappropriate for output due to its low visual quality. layer_profile_level_idc[ i ] indicates the conformance point of the representation of the current scalable layer. layer_profile_level_idc[ i ] is the exact copy of the three bytes comprised of profile_idc, constraint_set0_flag, constraint_setl_flag, constraint_set2_flag, constraint_set3_flag constraint_set4_flag, constraint_set5_flag, reserved zero 2bits and level_idc, as if these syntax elements were used to specify the profile and level conformance of the representation of the current scalable layer. NOTE 13 - The representation of a sub-picture scalable layer (sub_pic_layer_flag[ is equal to 1) does not conform to this Recommendation | International Standard, since the primary coded VCL NAL units with quality_ id equal to 0 that belong to a sub- picture scalable layer representation do not cover all macroblocks of the layer pictures with dependency id equal to dependency id| and quality id equal to 0. For sub-picture scalable layers, the violation of the constraint that the layer representations with quality id equal to 0 of primary coded pictures must cover all macroblocks of the corresponding layer pictures is ignored in the conformance point indication by layer_profile_level_idc[i] avg_bitrate| i indicates the average bit rate of the representation of the current scalable layer. The average bit rate for the representation of the current scalable layer in bits per second is given by BitRateBPS( avg_bitrate[i]) with the function BitRateBPS() being specified by: BitRateBPS(x)=(x&(214-1))10((>4) (G-370) The average bit rate is derived according to the access unit removal time specified in Annex C of this Recommendation International Standard. In the following, bTotal is the number of bits in all NAL units of the current scalable layer representation, t1 is the removal time (in seconds) of the access unit associated with the scalability i
