This application is a continuation of Application Ser. No. 10/747,139 filed on Dec. 30, 2003 now U.S. Pat. No. 7,145,043, which is a continuation of Application Ser. No. 09/339,191 filed on Jun. 24, 1999, now U.S. Pat. No. 6,804,456, which claims the benefit of Korean Application Nos. 98-23992 filed on Jun. 24, 1998, and 98-41757 filed on Oct. 2, 1998, in the Korean Industrial Property Office, now the Korean Intellectual Property Office. The disclosures of application Ser. Nos. 10/747,139 and 09/339,191 and Korean Application Nos. 98-23992 and 98-41757 are incorporated herein by reference.
It is fifth object of the present invention to provide a method for recording still picture group information consisting of video information for a still picture and video and audio information for a still picture having original audio data added thereto, and reproduction-related cell information, and reproducing a still picture or a still picture having original audio data added thereto.
It is sixth object of the present invention to provide a method for recording still picture group information, additional audio group information for after-recording and reproduction-related cell information, and reproducing a still picture, a still picture having original audio data added thereto, or a still picture having additional audio data added thereto in accordance with the recorded information.
It is seventh object of the present invention to provide an apparatus for recording still picture group information for grouping a large-capacity still picture and managing the same, additional audio group information for after-recording separately from the still picture group information, and reproduction-related cell information, and reproducing a still picture, a still picture having original audio data added thereto, or a still picture having additional audio data added thereto in accordance with the recorded information.
According to the present invention, there is provided a method for recording and/or reproducing audio and/or video data on a recordable and/or rewriteable recording medium including (a) recording a plurality of still pictures, (b) separating the plurality of still pictures into within a predetermined maximum number of groups and recording still picture group information and playback information related to reproduction, (c) recording additional audio data added to a desired still picture in a separate area, after the plurality of still pictures are recorded, and (d) recording additional audio group information for separating the additional audio data into within a predetermined maximum number of groups in order to manage the additional audio data at a group level, and information indicative of the additional audio data corresponding to the desired still picture, wherein the information indicative of the additional audio data is included in the still picture group information.
FIGS. 19A and 19B illustrate a flow chart showing a method for recording a still picture according to an embodiment of the present invention, that is, a method for recording a still picture and original audio data. First, it is determined whether a still picture or both a still picture and original audio data is recorded (step S101). Still picture group information is generated, identification for a still picture group is allocated, the number of still pictures in the still picture group is set to “0” and the start address of the still picture group in a still picture file is recorded (step S102). It is then determined whether a recording start signal of a still picture is input by a user or not (step S103). If the recording start signal is input, the still picture is recorded in the still picture file, identification information for the still picture is allocated to the still picture group information, the number of still pictures in the still picture group is increased by one and the size information of the still pictures is recorded in the video map (step S104).
FIG. 20 is a flow chart showing a method for recording additional audio data after recording a still picture according to a first embodiment of the present invention. First, additional audio group information is generated, identification information for an additional audio group is allocated, the number of additional audio parts in the additional audio group is set to “0” and the start address of the audio group is recorded in an additional audio file (step S201).
FIG. 21 is a flow chart showing a method for reproducing a still picture according to the first embodiment of the present invention, that is, a method for reproducing a still picture and original audio data added thereto. Referring to FIG. 21, PGC information and cell information are read (step S301). Identification information for a still picture group to be reproduced, playback start identification information and playback ending identification information are read from the cell information to read the still picture group information pointed to by the cell (step S302). Video map information for the video part corresponding to the playback start identification information in the read still picture group information is obtained to read the size of a video part, or both video map information and audio map information are obtained in the case of a still picture having original audio data to read the size of a video part and the size of an audio part (step S303).
1. A method of reproducing data from a recording medium comprising a first region, a second region, and a third region, the method comprising:
reading at least one of a plurality of still pictures from the first region;
reading at least one of a plurality of additional audio data from the second region, the read at least one additional audio data corresponding to the read at least one still picture;
reading, from the third region, connectivity information indicating a connectivity between the still pictures in the first region and the additional audio data in the second region;
managing the read at least one additional audio data at a group level according to at least one additional audio group information that arranges the read at least one additional audio data into an additional audio group according to the read information from the third region;
determining the connectivity between the read at least one still picture and the read at least one additional audio data according to the read connectivity information;
determining, from the read at least one additional audio group information, a start position of the additional audio group and sizes of each additional audio data in the additional audio group; and
reproducing the read at least one still picture and the read at least one additional audio data according to the determined connectivity, start position, and sizes.
2. The method of claim 1, wherein at least one of the plurality of still pictures comprises video data.
3. The method of claim 2, wherein a plurality of the still pictures comprise corresponding video data; and
the read connectivity information indicates sizes of the corresponding video data.
4. The method of claim 1, wherein at least one of the plurality of still pictures comprises video data and audio data.
5. The method of claim 4, wherein a plurality of the still pictures comprise corresponding video data and corresponding audio data; and
the read connectivity information indicates sizes of the corresponding video data and the corresponding audio data.
6. A method of reproducing data from a recording medium comprising a first region, a second region, and a third region, the method comprising:
reading still pictures stored in still picture groups in the first region;
reading additional audio data, corresponding to the still pictures, stored in additional audio groups in the second region;
reading general information from the third region;
determining, from the read general information:
a relationship between the read still pictures and the read additional audio data;
start positions on the recording medium for each of the still picture groups and the additional audio groups;
a size of a video part, or a size of a video part and a size of an audio part, for each of the still pictures in each of the still picture groups; and
a size of each of the additional audio data in each of the additional audio groups; and
reproducing the read still pictures and the read additional audio data according to the determined relationship, the determined start positions, and the determined sizes.
7. The method of claim 6, wherein at least one of the still pictures comprises the video part.
8. The method of claim 6, wherein at least one of the still pictures comprises the video part and the audio part.
