Patent ID: 7483348

Claim:
A recording/reproducing apparatus having a function of recording/reproducing video/audio data in a first recording medium divided into a first and a second storage region and copying the video/audio data in a second recording medium which is detachable, the recording/reproducing apparatus comprising: a first recording unit that records the video/audio data in the first storage region of the first recording medium; a decoding unit that decodes the video/audio data; a resolution converting unit that converts the video/audio data decoded by the decoding unit into video/audio data with a prescribed bit rate; an encoder unit that encodes the video/audio data with the bit rate converted by the resolution converting unit in a format of the second recording medium; a second recording unit that records the video/audio data encoded by the encoder unit in the second storage region of the first recording medium; a copying unit that copies the video/audio data recorded in the second storage region of the recording medium into the second recording medium; an evaluating unit that evaluates, whenever a predetermined time elapses, respective evaluated scores for a plurality of evaluation items of the video/audio data recorded in the first and second storage region, and totals the evaluated scores to evaluate a saving priority of the video/audio data recorded the first and the second storage region of the first recording medium; a detecting unit that monitors, whenever a predetermined time elapses, empty capacities of the first and the second storage region of the first recording medium to detect shortage in the empty capacities of the first and the second storage region of the first recording medium; and a canceling unit that cancels, when shortage in the empty capacities of the first and the second storage region of the first recording medium is detected, the video/audio data with a lower saving priority recorded in the first and the second storage region of the first recording medium, exclusive of the video/audio data protection-set.
