Buffer memory management apparatus and method for reproducing interactive information storage medium, and interactive information storage medium

摘要

A buffer memory management apparatus and method reproducing an interactive information storage medium, and the interactive information storage medium, the buffer memory management method including: collectively reading collective-processing interactive data from the information storage medium when the information storage medium is loaded in a reproducing device or in an initial execution of a predetermined application after the information storage medium is loaded in the reproducing device and loading the collective-processing interactive data in a buffer memory; and reading conditional-processing interactive data, which is conditionally read according to a user's input condition or a reproducing status of the information storage medium, and loading the conditional-processing interactive data in the buffer memory. Therefore, a response speed of a device reproducing an interactive information storage medium can be increased and compatibility between reproducing devices can be achieved since compaction of a buffer memory is unnecessary by minimizing memory fragmentation.
