Abstract:
1. A moving picture decoding system comprising: a recording medium on which multiplexed data is recorded, the multiplexed data being obtained by multiplexing (i) coded data obtained by coding a moving picture and (ii) audio data obtained by coding an audio signal; and a decoding apparatus which decodes the coded data and the audio data from said recording medium, wherein the coded data is obtained by using a coding method for coding blocks while switching between frame coding and field coding on a block-by-block basis, the coded data being included in the multiplexed data recorded on said recording medium, wherein the coding method includes: wherein in the case where the field decoding is performed on the block, said reference frame/field specification unit is operable to: specify, as the reference field, a field having a parity that is the same as a parity of the block, out of two fields that make up the reference frame specified according to the frame reference index for decoding, when the extracted reference index has a value that is double a value of one of the frame reference indices for decoding; and specify, as the reference field, a field having a parity that is different from the parity of the block, out of the two fields that make up the reference frame specified according to the frame reference index for decoding, when the extracted reference index has the value that is double the value of the one frame reference index, plus one.
