Abstract
A variable transfer rate control coding apparatus which can distribute codes of an amount most suitable to the contents of a moving picture to be recorded and to a recording medium, on which information is recorded by this transfer rate coding apparatus, by obtaining an amount of codes to be temporarily generated in each unit period of time by a temporary or tentative coding, and then storing a temporary transfer rate (namely, a value of the temporary amount of codes to be generated in each unit period of time), and setting a target transfer rate (namely, a target value of an amount) of codes to be sent in each unit period of time from a total of the temporary transfer rates and the recordable capacity of the recording medium and next performing an actual or real coding according to the target transfer rates.
