Abstract

A plurality of audio object (AOB) files and a plurality of picture object (POB) files are stored. Default Play list Information and sets of Playlist Information each show an order in which AOBs stored in the plurality of AOB files are to be reproduced. The DPLGI includes DPLI_POB_SRPs that specify at least one POB to be displayed during the playback period of AOBs indicated by the playback order given in the Default Playlist Information. The TKGI includes TKI_POB_SRPs that specify at least one POB to be displayed only during the playback period of a particular AOB out of the AOBs indicated by the playback order given in the Default Playlist Information.

Claims

1. A program stored on a computer-readable storage medium used for enabling a computer to execute a playback procedure for a semiconductor memory card, the semiconductor memory card containing:

an audio sequence including a plurality of audio objects;

a plurality of still image objects;

at least one piece of playback route information which indicates an order in which audio objects, out of the plurality of audio objects in the audio sequence, are to be played back;

at least one piece of first pointer information, wherein each of the at least one piece of first pointer information corresponds to a piece of the playback route information and specifies at least one still image object to be displayed when the audio objects in the order indicated by the corresponding piece of playback route information are played back; and

at least one piece of second pointer information, wherein each of the at least one piece of second pointer information corresponds to an audio object in the audio sequence and specifies at least one still image object that should be displayed during playback of the corresponding audio object;

said program comprising;

computer executable code operation to cause the computer to play back audio objects in the audio sequence one at a time in the order indicated by the at least one piece of playback route information;

computer executable code operable to cause the computer to display the at least one still image object specified by the at least one piece of first pointer information throughout playback of the audio objects in the audio sequence; and

computer executable code operable to cause the computer to display the at least one still image object specified by the at least one piece of second pointer information throughout playback of a particular audio object corresponding to the at least one piece of second pointer information.

2. A program according to claim 1, wherein:

computer executable code operable to cause the computer to display the at least one still image object specified by the at least one piece of second pointer information is further operable to cause the computer to display a combined image produced by combining the at least one still image object specified by the at least one piece of second pointer information with the at least one still image object specified by the at least one piece of first pointer information.

3. A program stored on a computer-readable storage medium used for enabling a computer to execute a recording procedure for a semiconductor memory card that stores a plurality of still image objects and an audio sequence including a plurality of audio objects, said program comprising:

computer executable code operable to cause the computer to assign, to playback route information, at least one still image object that is to be displayed throughout playback of the plurality of audio objects in the audio sequence, and assign at least one still image object that is to be displayed throughout playback of a particular audio object to the particular audio object; and

computer executable code operable to cause the computer to record onto the semiconductor memory card;

at least one piece of playback route information which indicates an order in which audio objects, out of the plurality of audio objects in the audio sequence, are to be played back;

at least one piece of first pointer information, wherein each of the at least one piece of first pointer information corresponds to a piece of the playback route information and indicates the at least one still image object assigned to the audio sequence; and

at least one piece of second pointer information, wherein each of the at least one piece of second pointer information corresponds to an audio object in the audio sequence and indicates the at least one still image object assigned to the particular audio object.
