Abstract: A system and corresponding devices are disclosed for automatically providing a user with metadata related to data provided by the user, the data representing media content, comprising: a. a context storage means (1) adapted for storing context data relating to and for each of a predetermined set of events; b. an annotation storage means (2) adapted for storing annotation data for each of the set of events; c. an uploading module (3) for uploading the data from a user into the system; d. an association means (4) for associating a predetermined event and context to the data. Also a corresponding method for automatically providing a user with annotation data related to data provided by the user is disclosed.

Abstract: A broadband telecommunication system with several content servers (BS1-4) providing channels of multimedia data to subscribers (TV1-4) coupled thereto via a access unit, preferably an Asymmetric Digital Subscriber Line (ADSL) Subscriber Access Multiplexer (ASAM). The content servers are also coupled to the ADSL Subscriber Access Multiplexer (ASAM) via a Zapping Service Box (ZSB) that merges the channels into a composed channel transmitted to the ASAM via a single zapping channel (ZC). When a subscriber (TV3) requests a selected channel, and when this channel is not yet directly available at the ASAM, the latter immediately provides to this subscriber the composed channel until the ASAM receives the requested channel directly from the content server providing it.

Abstract: The present invention relates to a multicast traffic control unit (21) for use in a data communication system (1) operable to transmit multicast traffic, and adapted: to receive membership reports (41 to 45) from at least one station (11 to 13), whereby memberships of multicast groups are notified, to report at least one membership (41, 44) out of said memberships to a multicast router (31) of the data communication system. A multicast traffic control unit according to the invention is further adapted, before reporting the at least one membership to the multicast router: to estimate a total amount (X) of multicast traffic which the multicast router would supposedly forward towards the at least one station on account of the at least one membership, to select the at least one membership such that the so-estimated total amount does not exceed a configurable threshold (Xmax).

Abstract: The access multiplexer (DSLAM) according to the present invention incorporates a remote host-based intrusion detection system (RHIDS) to detect malicious activity on a large amount of access subscriber connected to the access multiplexer by remotely analyzing systems integrity and statistical behaviors of those access subscribers, and eventually also incorporates a network-based intrusion detection system (NIDS2) to detect malicious activity on all access subscribers (S21, S22 . . . S2N) connected to the access multiplexer by analyzing incoming and outgoing traffic for attack signature patterns.
