Patent ID: 8224154

Claim:
A recording control apparatus for controlling recording of first, second, and third data series onto an optical disk, the apparatus comprising: first data extracting means for extracting video and audio data having a first data amount for each frame from the first data series, the first data amount being a data amount in accordance with a data amount required for reproduction of one frame of an image for a first reproduction time; second data extracting means for extracting frame metadata having a second data amount for each frame from the second data series, the second data amount being a data amount in accordance with a data amount required for reproduction of the frame metadata for a second reproduction time that is different from the first reproduction time; first recording-control means for performing recording-control to record data having the first data amount for the first data series and data having the second data amount for the second data series onto the optical disk so that frame metadata for each frame is recorded physically adjacent the video and audio data recorded for each frame, wherein the video and audio data and frame metadata which have a same reproduction time are periodically arranged at close positions in a circumferential direction of the optical disk in a form of annular rings respectively; and second recording-control means for performing recording-control to record the third data series onto the optical disk only after all first and second data series are finished being recorded on the optical disk in the form of annular rings by the first recording control means so that the third data series is physically arranged on the optical disk independently of the periodically arranged first data series and the second data series, wherein the third data series is separately recorded at an inner circumference side in a contiguous manner and wherein the third data series is clip metadata recorded for each clip.
