Abstract:
1. A recording and reproduction apparatus, comprising: a recording and reproduction control unit, for controlling the recording and reproduction of moving picture data on a recording medium, and for controlling a skip search for a predetermined time; a scene change detector for detecting a scene change location in data received while recording moving picture data; and a selection unit employed by a user to change to a special skip search mode and to a normal skip search mode, wherein: while motion picture data is being recorded, the recording and reproduction control unit records, on the recording medium, information for a scene change location obtained by the scene change detector, in correlation with an I picture of reference moving picture data that is a reference at the time a scene change is detected; for moving picture data for which differential information indicating a difference from the reference moving picture data does not exceed a specific time, which is shorter than the predetermined time for the skip search, the recording and reproduction control unit records an I picture for the moving picture data on the recording medium, in correlation with the differential information; when the differential information indicating a difference from the reference moving picture data exceeds the specific time, which is shorter than the predetermined time for the skip search, the recording and reproduction unit clears the differential information to be correlated with the moving picture data until the next scene change is detected; and when the special skip search mode is selected by the selection unit, and when a skip search is started at a reproduction position upon receiving a skip search instruction during the reproduction of moving picture data, the recording and reproduction control unit reads, from the reproduction position, scene change location information, or differential information, that is correlated with an I picture at a destination reached by skipping for a predetermined time, and executes the special skip search mode to perform a skip search up to a location address for the reference moving picture data that is obtained based on the scene change positioning information or the differential information that has been read.
