In a recording method, in particular, for recording still pictures, while classifying the still pictures and managing the still pictures classified, wherein still picture data and management information for managing that still picture data are recorded therein. The management information includes information for classifying the still picture data into a classifying unit, each, and also includes a file format of the still picture data classified into the classifying unit mentioned above.

There is provided an optimum format for recording an AV stream of a digital broadcast or the like, omitting a reproduction of an unnecessary stream previous or subsequent to the recorded stream, and controlling a genuinely needed reproduction range in frame units.A configuration is such as to record a GOP position of a reproduction start of a recorded AV stream file, and a frame position thereof, as well as a GOP position of a reproduction finish and a frame position thereof, in a management file.

To provide a recording method for recording still images that is particularly suitable for sorting still images and recording and managing the sorted still images, there is disclosed a recording method for recording still image data and management information for managing the still image data, with the management information including information based on which a plurality of pieces of the still image data are sorted into sorting units, and an earliest one and a latest one of photographing dates at which the pieces of still image data sorted into each of the sorting units are respectively taken.

A technique is provided for reproducing information from a recording medium, on which there are recorded a plurality of picture information sets; presentation time values, each associated with a corresponding one of the picture information sets; picture information record marks, each of which is associated with a corresponding one of the presentation time values; clip information specifying what position on the recording medium is associated with each of the presentation time values; and reproducing order specifying information which specifies in what order the picture information sets are to be reproduced. Picture information is reproduced through the steps of detecting the presentation time value of a picture information set to be retrieved from the corresponding picture information record mark; using said clip information to detect the recording position on the recording medium which corresponds to the detected presentation time value; and reproducing picture information from the detected recording position.

As a method of quickly displaying a thumbnail for navigation display of an AV stream, it is necessary to associate the AV stream with a thumbnail file when recording the thumbnail file separately from the AV stream file. The association, therefore, is performed by use of a serial number of the recorded AV stream file as a name of the related thumbnail file.

In a case of recording and managing a program which has a plurality of image streams in one program, it is necessary to address which stream a logic table which records a position of an I picture for high-speed fast forwarding and rewinding corresponds to.In a recording method which records a digital broadcast, in particular one method is provided which records and manages the program which has the plurality of image streams in one program.In the case in which there are a plurality of image streams in one program, as information which indicates which stream the logic table of the I picture, for carrying out the fast forwarding and rewinding operations quickly, corresponds to, a component tag fixed by a European or Japanese digital broadcast standard is recorded with the logic table. Also, in the event of recording an American broadcast stream, in digital broadcast standards of which there is no component tag regulation, a value of a program map table (PMT), which indicates one of the plurality of streams, is recorded.
