Method for managing play lists on a rewritable storage medium

Abstract

The present method that manages play lists on a rewritable storage medium records additional flag information indicating whether an A/V stream clip is allowed to be partially deleted or edited in a play list corresponding to the A/V stream clip recorded on a rewritable optical disk (BD-RW) and selectively executes a user's request to edit the A/V stream clip depending on the flag information, thereby effectively preventing programs or movies the copyright of which should be protected from being edited illegally.

Dependencies are inferred from the claim text.
