Patent ID: 8238723

Claim:
An optical disk recording device, comprising: a data table in which a plurality of reference bit rates are stored; encoding means which encodes a video signal in an analog format, into video data in a digital format by one of the reference bit rates stored in the data table; recording means which records the video data encoded by the encoding means upon an optical disk which is loaded into the optical disk recording device; and changeover timing calculating means which: calculates a uniform bit rate by dividing the capacity which can be recorded upon the optical disk by an appointed time period for video recording the video signal; combines, upon the time axis, a first reference bit rate which exceeds the uniform bit rate and is closest to the uniform bit rate and a second reference bit rate which is less than or equal to the uniform bit rate and is closest to the uniform bit rate, from among the reference bit rates stored in the data table; and calculates a changeover time period between the first reference bit rate and the second reference bit rate so as to occupy the capacity which can be recorded, wherein the encoding means: encodes the video signal into the video data by the first reference bit rate or the second reference bit rate; and changes over between the first reference bit rate and the second reference bit rate at the changeover time period which is calculated by the changeover timing calculating means.
