In one exemplary embodiment, a data area of the recording medium stores at least one still image in a first file and audio data in a second file. A playlist area of the recording medium stores at least one playlist, and the playlist links the first and second files. For example, the playlist includes navigation information providing presentation information regarding the first and second files.
In one exemplary embodiment, the playlist includes one of a playitem field and a sub-playitem field providing the navigation information for the still image file. According to a further exemplary embodiment, another one of a playitem field and a sub-playitem field provides navigation information for the audio data. In another exemplary embodiment, the playlist includes includes mark information, and the mark information includes a mark associated with a point in the audio data and which points to the still picture.
As shown in FIG. 1, the root directory contains at least one BD directory. The BD directory includes general files (not shown), a PLAYLIST directory in which playlist files (e.g., *.mpls) are stored, a CLIPINF directory in which clip information files (*.clpi) are stored, and a STREAM directory in which MPEG-2-formatted A/V stream clip files (*.m2ts), corresponding to the clip information files, are stored.
The STREAM directory includes MPEG-2-formatted A/V stream files called clips or clip files. The A/V stream includes source packets of video and audio data. For example, a source packet of video data includes a header and a transport packet. A source packet includes a source packet number, which is generally a sequentially assigned number that serves as an address for accessing the source packet. Transport packets include a packet identifier (PID). The PID identifies the sequence of transport packets to which a transport packet belongs. Each transport packet in the sequence will have the same PID.
FIG. 6 illustrates one exemplary embodiment of the navigation information for still images provided by associated playlist marks. A playlist file includes a playlist mark information field called �PlayList Mark�. As shown in FIG. 6, the playlist mark �PlayListsMark� information field indicates a length of the information field and a number of the playlist marks �number_of_PlayList_marks� in the playlist. In case of the BD-RE, the �length� field has a value of �26 bytes�. In case of the BD-ROM in accordance with the invention the length field may have a value greater than 26 bytes. For each playlist mark, the playlist mark �PlayListsMark� information field indicates the mark type �mark_type�, a time stamp �mark_time_stamp�, duration �duration�, maker's information �makers_information�, and maker's name �maker_name�.
The mark type indicates the type of mark. For example, when a mark indicates the beginning of a chapter, the mark type �mark type� identifies the associated mark as a chapter mark. As further shown in FIG. 6, if a mark is of the still type, then an index number of the associated still image or images recorded on the BD-ROM �ref to_still_image_index� is provided.
FIG. 7A illustrates another exemplary embodiment of the navigation information for still images provided by associated playlist marks. As shown, this embodiment is the same as the embodiment of FIG. 6 except that if the mark is a still mark (e.g., mark type=0�10) then additional information regarding the reproduction of the still image or images is provided in association with the still mark. Specifically, the following indicator fields are provided: an indicator of the number of still images associated with the still mark �number_of still_images�, an indicator of the display timing �display_timing_mode�, an indicator of the display order �display_order_mode�, an indicator of the display effect �display_effect_mode� and an indicator of the period for the display effect �display_effect_period�.
If the �display_timing_mode� field is �0�, it indicates an automatic slide show. If the �display_timing_mode� field is �1�, it indicates a browsable still or slideshow operation, which displays still images based on key input by a user. If the �display_order_mode� field is �0�, it indicates a sequential still operation in which the still images are to be displayed sequentially. If the �display_order_mode� field is �l�, it indicates a random still operation in which the still images are to be displayed in a random manner.
As illustrated in FIG. 9A, the still indicator �PlayListStillIndicator� is a new information field added to a playlist file �PlayList_File�. This new information field indicates a length of the information field and a number of the playlist stills �number_of_PlayList_stills�. For each playlist still, the playlist indicator �PlayListStillIndicator� information field indicates a time stamp �still_time_stamp�, a start index number of the associated still image(s) recorded on the BD-ROM �ref_to_still_start_index�, and a number of still images �number_of_still_images.�
If the CPI type given in the clip information file associated with the playitem is an EP map type signified by CPI type=1, then the playitem includes an STC reference �ref_to_STC�id� on the clip indicated by the clip information file name �Clip�Information_file_name�.
The playitem also includes IN_time and OUT_time fields. The �IN_time� field takes up 2 bytes and indicates the index number of the first still image among the linked still images stored in the still image file and the �OUT-time� field indicates the index number of the last still image among the linked still images.
Furthermore, as shown in FIG. 11A, if the playitem is a still playitem, then the number of still images �number_of_still_images� is provided; and for each still image, the following information is provided: a duration 'duration to display the still image, an indicator of the display timing �display_timing_mode�, an indicator of the display order �display_order_mode�, an indicator of the display effect �display_effect_mode� and an indicator of the period for the display effect �display_effect_period�. These indicators were defined above with respect to FIG. 7A.
The sub-playitem information field also includes an indicator �Clip_codec�identifier� and a type indicator �SubPlayItem_type� both indicating whether the playitem is a still playitem and associated with one or more still images. For example, the �Clip_codec_identifier� field may indicate the encoding format of a still image such as �JPEG�, which then serves to indicate that the playitem is a still playitem for still image display. With respect to the type indicator �SubPlayItem_type�, if the type indicator �SubPlayItem_type� equals, for example, �2�, then this indicates the sub-playitem is associated with a sub-path for displaying one or more associated still images.
The sub-playitem further includes an STC reference �ref_to_STC_id� for the clip indicated by the clip information file name �Clip_Information_file_name�, an id of the playitem containing this sub-playitem �sync_Playitem_id�, and an indication �Sync_start_PTS_of_PlayItem� of a presentation-time in the playitem indicated by the �sync_Playitem_id.�
Furthermore, as shown in FIG. 13A, if the playitem is a still playitem, then the number of still images �number_of_still_images� is provided; and for each still image, the following information is provided: a duration �duration� to display the still image, an indicator of the display timing �display_timing_mode�, an indicator of the display order �display_order_mode�, an indicator of the display effect �display_effect mode� and an indicator of the period for the display effect �display_effect_period�. These indicators were defined above with respect to FIG. 7A.
