Checking a batch of DVD titles to be archived

摘要

Administrating content of a digital video disc (DVD) having, on-disc, a database involves storing, externally to the DVD, information of the database. Based on the stored information, a check is made as to whether the DVD is operable to accommodate a proposed change to the content. The change on the DVD is made and the on-disc database is correspondingly updated, if the check determines that the DVD is so operable, e.g., if remaining resources of the DVD suffice to make the change. Preferably, the making of the change and the updating on-disc are interactively subject to the user's acceptance by means of a user interface.
