note: A term used to prefix informative remarks. This term is used exclusively in an informative context. 3.100 opposite parity: The opposite parity of top is bottom, and vice versa. 3.101 output order: The order in which the decoded pictures are output from the decoded picture buffer. 3.102 P slice: A slice that is not an SP slice that may be decoded using intra prediction or inter prediction using at most one motion vector and reference index to predict the sample values of each block. 3.103 parameter: A syntax element of a sequence parameter set or a picture parameter set. Parameter is also used as part of the defined term quantisation parameter. 3.104 parity: The parity of a field can be top or bottom. 3.105 partitioning: The division of a set into subsets such that each element of the set is in exactly one of the subsets. 3.106 picture: A collective term for a field or a frame. 3.107 picture parameter set: A syntax structure containing syntax elements that apply to zero or more entire coded pictures as determined by the pic_parameter_set_id syntax element found in each slice header. 3.108 picture order count: A variable that is associated with each coded field and each field of a coded frame and has a value that is non-decreasing with increasing field position in output order relative to the first output field of the previous IDR picture in decoding order or relative to the first output field of the previous picture, in decoding order, that contains a memory management control operation that marks all reference pictures as "unused for reference". 3.109 prediction: An embodiment of the prediction process. 3.110 prediction process: The use of a predictor to provide an estimate of the sample value or data element currently being decoded. 3.111 predictive slice: See P slice. 3.112 predictor: A combination of specified values or previously decoded sample values or data elements used in the decoding process of subsequent sample values or data elements. 3.113 primary coded picture: The coded representation of a pic
