<p>A high efficiency coding recording and reproducing apparatus, wherein intra-frame coded and inter-frame coded data are recorded and the recorded coded data are reproduced and decoded, comprises a coding means coding a predetermined block within one picture with the frequency converted; a low region component coding means variable length coding the low region component of the conversion coefficient from the coding means; a high region component coding means variable length coding the high region component of the conversion coefficient from the coding means; and a recorded signal arranging means outputting in a synchronous block unit of each synchronous signal the outputs as multiplexed of the low region component and high region component coding means and outputting the output of the low region component coding means as arranged in a predetermined position of the synchronous block. <IMAGE></p> |
