Recording apparatus, recording program, and recording method
First Claim
1. A recording apparatus for writing a plurality of contents stored in a first recording medium to a second recording medium that is smaller in capacity than the first recording medium, each content being obtained by encoding moving pictures, the recording apparatus comprising:
- a first duplicating unit operable to copy at least one of the contents to the second recording medium; and
a second duplicating unit operable to re-encode a remaining one of the contents to reduce a size thereof, and to write the re-encoded content to the second recording medium, wherein a bit rate to be allocated to the remaining content upon re-encoding is determined based on (i) a residual capacity of the second recording medium that is left after subtracting, from a current capacity, a size of the content to be copied by the first duplicating unit, and (ii) a reproduction time of the remaining content to be re-encoded by the second duplicating unit.

Abstract
Disclosed is a recording apparatus for recording a plurality of audio-visual contents stored in a HD to a writable DVD. A drive controller 15 copies at least one of the contents stored in the HD to the DVD. If the available capacity of the DVD left after the copying falls short to copy a remaining content, the remaining content is re-encoded prior to being recorded in the DVD. The bit rate to be allocated to the remaining content upon re-encoding is calculated from the available capacity of the DVD and the reproduction time of the remaining content to be re-encoded.

12. A program run by a computer for writing a plurality of contents stored in a first recording medium to a second recording medium that is smaller in capacity than the first recording medium, each content being obtained by encoding moving pictures, the program comprising:
-
a first duplicating step of copying at least one of the contents to the second recording medium; and
a second duplicating step of re-encoding a remaining one of the contents to reduce a size thereof, and writing the re-encoded content to the second recording medium, wherein a bit rate to be allocated to the remaining content upon re-encoding is determined based on (i) a residual capacity of the second recording medium that is left after subtracting, from a current capacity, a size of the content to be copied in the first duplicating step, and (ii) a reproduction time of the remaining content to be re-encoded in the second duplicating step. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A recording method for writing a plurality of contents stored in a first recording medium to a second recording medium that is smaller in capacity than the first recording medium, each content being obtained by encoding moving pictures, the recording method comprising:
-
a first duplicating step of copying at least one of the contents to the second recording medium; and
a second duplicating step of re-encoding a remaining one of the contents to reduce a size thereof, and writing the re-encoded content to the second recording medium, wherein a bit rate to be allocated to the remaining content upon re-encoding is determined based on (i) a residual capacity of the second recording medium that is left after subtracting, from a current capacity, a size of the content to be copied in the first duplicating step, and (ii) a reproduction time of the remaining content to be re-encoded in the second duplicating step.
