Abstract:
1. An encoded data recording apparatus for recording encoded data composed of first data generated based on original data having correlations on the time axis in an initial frame timing thereof and of a plurality of second data generated respectively in a plurality of frame timings subsequent to said initial frame timing, said first data having an independent meaning alone and said plurality of second data containing mainly a difference between the original data of a current frame and the original data of the preceding frame respectively, said apparatus comprising: encoded data input means for inputting said encoded data; data reproduction processing means for reproducing said original data based on the first data and the second data of the encoded data inputted by means of this data input means; recording period specifying means for specifying the recording period of said encoded data; and recording control means for recording the original data reproduced by said data reproduction processing means in the recording period concerned in a recording medium when the recording period is specified by said recording period specifying means in period inputting said encoded data, a re-encoding control part configured to re-encode the reproduced original data into the first data and the second data except in a period when the encoded data are input by the encoded data input means and during the recording period so that no concentrated processing load is realized so as to reduce the processing burden of a central processing unit or a data signal processor (DSP).
