Abstract: A recording/reproducing apparatus (115) includes a storage section (117) having a content attribute database (DB1) and a point database (DB2). Further, a point calculating section (120) of the recording/reproducing apparatus (115) extracts attribute information sets for each content item from the content attribute database (DB1). Further, deletion factor points associated with deletion factors corresponding to the extracted attribute information sets are extracted from the point database (DB2) for each content item, and evaluation points are calculated in accordance with the extracted plural deletion factor points. This allows the user to appropriately reserve a space required in a recording medium.

Abstract: To enable a recording device recording a video/audio signal and information necessary for utilizing the video/audio signal to copy the video/audio signal with the converted bit rate, encoding format, etc., to another recording device when utilizing the video/audio signal by the another recording device, and to move only the information necessary for utilizing the video/audio signal between the recording device and the another recording device. A recording device comprises: an input portion that inputs a video/audio signal; a recording portion that records the video/audio signal and information necessary for utilizing the video/audio signal; and a converting portion that converts the recorded video/audio signal. The recording device, leaving the original video/audio signal, copies the video/audio signal whose bit rate, encoding format, etc.

Abstract: A recording and reproducing apparatus for recording and reproducing the stream of a content, in which video image and audio streams are extracted from streams of a predetermined format, and a new stream, the edit of which can be freely carried out, is created from the streams and recorded. A recording and reproducing apparatus comprises an input/output interface for inputting a stream, a stream conversion processing portion for converting an input stream of a predetermined format into a stream comprising only a video image stream and an audio stream and a recording medium writing control portion for writing and recording the converted stream in a recording medium. The recording medium writing control portion writes managing information representing that the stream converted by the stream conversion processing portion is recorded in a predetermined area (manufacturer definition area) of the recording medium.
