Abstract: According to one embodiment, a video reproducing device includes a separation controller and a processor. The separation controller is configured to receive a video signal and an audio signal synchronized with the video signal, and to separate a background sound and a voice in the audio signal. The processor is configured to select at least one of a plurality of image quality improvement processing schemes based on an analysis of the voice and the background sound, and to apply the selected image quality improvement processing scheme to the video signal.

Abstract: According to one embodiment, an apparatus for recording audio-video information includes a storage device configure to store audio-video information containing video data and audio data, an optical disc drive configured to record the audio-video information in a recoding-type optical disc, detecting section configure to detect a free space available in the recoding-type optical disc, when the audio-video information is being recorded in the recoding-type optical disc, and analysis-type divided-recording control section configure to analyze the content of the audio-video information when the detected free space is smaller than a preset value, thereby detecting dividing points, to divide the audio-video information into parts in accordance with the detected dividing points, and to control recording the parts of the audio-video information in the recoding-type optical disc and at least one other recoding-type optical disc.

Abstract: Multimedia data embedded with control information for playback control are recorded on a recording medium in predetermined playback units. The recording medium also stores a management table, which manages a first file that defines the physical locations of the multimedia data and control information, and a second file that defines the physical locations of at least part of the multimedia data. A CPU executes playback control based on the first or second file by looking up the management table. Since a plurality of files that share multimedia data are used, the respective processes can be efficiently done without recording different versions of identical multimedia data.
