Abstract: A method of controlling access to a content item in a domain comprising a set of mutually authenticated devices, the method comprising deriving one or more domain-specific rights from a right associated with the content item, the one or more domain-specific rights being bound to the domain and allowing the devices in the domain aces to the content item. Also system comprising a set of mutually authenticated devices, said set making up a domain, the system comprising a central rights manager arranged for executing said method.

Abstract: A video information stream distribution unit distributes streams such as MPEG streams that contain packets making up sub-streams. Each packet having an identification code that identifies the sub-stream to which the packet belongs. The stream also contains table information that relates programs to said identification codes. The distribution unit generates a new stream from a received stream. In the new stream selected packets from the received stream are copied that have identification codes related to a selected program. In the new stream the table information for the selected program is included with an increased repetition rate in comparison with an incoming repetition rate of the table information in the received stream, at least temporarily during an initial time interval following a change of selection of the selected program. Thus, latency involved with access to the new stream is reduced.

Abstract: Method and system for converting a first data stream (10) received from a network (12) into a second data stream (16) for delivery to an end terminal (18). The first data stream (10) has a first data rate, and comprises at least one data packet stream of a predetermined type. The system comprises a re-multiplexer (25) which is arranged for recovering the at least one data packet stream of the predetermined type from the first data stream (10). The re-multiplexer (25) is further arranged for re-multiplexing the at least one data packet stream using a predetermined bit rate to provide the second data stream (16) with a fixed bandwidth.
