Method of reproducing interactive graphic streams from information storage medium

An apparatus to provide a visual display of interactive graphics by reproducing one interactive graphics stream from among one or more interactive graphics streams from an information storage medium, the apparatus comprising:

• a processor which obtains attribute information in a player status register in the reproducing apparatus;
• and
• a decoder which reads and reproduces one interactive graphics stream corresponding to the obtained attribute information from among the one or more interactive graphics streams from the information storage medium, the one interactive graphics stream being used to control reproduction of audio-visual data from the information storage medium and being reproduced with the audio-visual data,
• wherein the one or more interactive graphics streams can be changed by navigation commands related to the reproduction of the audio-visual data and cannot be changed by a user's operation.

A method of reproducing one interactive graphics stream from among one or more interactive graphics streams from an information storage medium, via a reproduction apparatus providing a visual display of interactive graphics, comprising:

• obtaining attribute information in a player status register in the reproducing apparatus;
• and
• reading and reproducing one interactive graphics stream corresponding to the obtained attribute information from among the one or more interactive graphics streams from the information storage medium, the one interactive graphics stream being used to control reproduction of audio-visual data from the information storage medium and being reproduced with the audio-visual data,
• wherein the one or more interactive graphics streams can be changed by navigation commands related to the reproduction of the audio-visual data and cannot be changed by a user's operation.

An apparatus to provide a visual display of interactive graphics by reproducing one interactive graphics stream from among one or more interactive graphics streams from an information storage medium, the apparatus comprising:

• a processor which reads attribute information from a player status register number 18 in the reproducing apparatus, and sets a value in a player status register number 0 in the reproducing apparatus according to the read attribute information;
• and
• a decoder which reads and reproduces one interactive graphics stream corresponding to the value in the player status register number 0 from among the one or more interactive graphics streams from the information storage medium, the one interactive graphics stream being used to control reproduction of audio-visual data from the information storage medium and being reproduced with the audio-visual data,
