Abstract: A method and a system for restoring domain management for a domain in which content access rights are shared between one or more devices, where the domain management was executed by a first demean management device and is discontinued by this first domain management device. The first domain management device registers one or more characteristics of the domain at a domain registration server. After discontinuation of the domain management by the first domain management device, a second domain management device sends a request to the domain registration server for obtaining the right to manage the domain. The domain registration server provides the right to manage the domain together with the at least one of the one or more registered characteristics of the domain.

Abstract: The invention relates to a method and a system for restoring domain management for a domain (108) in which content access rights are shared between one or more devices (106, 110, 112, 118, 122, 124), wherein the domain management was executed by a first domain management device (106) and is discontinued by this first domain management device (106). The first domain management device (106) registers one or more characteristics of the domain (108) at a domain registration server (114). After discontinuation of the domain management by the first domain management device (106), a second domain management device (118) sends a request to the domain registration server (114) for obtaining the right to manage the domain (108). The domain registration server (114) provides the right to manage the domain (108) together with at least one of the one or more registered characteristics of the domain (108).

Abstract: A virtual title copying system and method that prevents redundant copying of content from a source medium to a destination medium during a copy transaction. Included is a system (24) that determines if a content section to be copied has an associated copy transaction identifier (30) at the source (12) and destination (16) medium; and a system (26) that generates and assigns a new copy transaction identifier to the source and destination medium during the copy transaction if no copy transaction identifier exists at the source and destination medium.
