in scalable extension NAL unit: A coded slice NAL unit that contains an El slice, EP slice, or an EB slice. G.3.9 complementary reference field pair: A collective term for two reference fields that are in consecutive access units in decoding order as two coded fields, where the target dependency representations of the fields share the same value of the frame syntax element and where the second field in decoding order is not an IDR picture and the target dependency representation of the second field does not include a memory_management_control_operation syntax element equal to 5, or a complementary reference base field pair. Rec. ITU-T H.264 (01/2012) G.3.10 complementary reference base field pair: Two reference base fields that are associated with two coded fields that are in consecutive access units in decoding order, where the target dependency representations of the coded fields share the same value of the frame_num syntax element and where the second coded field in decoding order is not an IDR picture and the target dependency representation of the second coded field does not include a nemory_management_control_operationsyntax element equal to 5. A complementary reference base field pair is a complementary reference field pair. G.3.11 dependency representation: A subset of VCL NAL units within an access unit that are associated with the same value of the dependency id syntax element, which is provided as part of the NAL unit header or by an associated prefix NAL unit, and the same value of the redundant_pic_cnt syntax element. A dependency representation consists of one or more layer representations. G.3.12 EB slice: A slice that may be decoded using intra prediction or inter prediction or inter-layer prediction from syntax elements and derived variables of the reference layer representation. For inter-prediction of EB slices at most two motion vectors and reference indices are used to predict the sample values of each block. G.3.13 EI slice: A slice that is not an I slice or SI slice that is decoded using in
