Abstract: The present disclosure generally discloses improvements in computer performance for delivery of content via a wireless communication network. The present disclosure generally discloses improvements in computer performance for delivery of content to wireless end devices via a wireless communication network using unicast services and multicast-broadcast services of the wireless communication network based on a service switching capability configured to support dynamic and opportunistic switching between the unicast services and multicast-broadcast services of the wireless communication network. The service switching capability may be configured to support dynamic and opportunistic switching between use of unicast service and use of multicast-broadcast service for a content item on a serving cell based on a number of wireless end devices on the serving cell that are receiving or requesting the content item.

Abstract: A procedure to broadcast digital multimedia contents to subscribers, where a first digital data transport stream broadcast to subscribers from a head end (12) via a first telecommunications network other than a telecommunications network based on an Internet IP protocol is received in a customer device (15); transmission from a first retransmission unit (153) of a lost packet petition message to a second retransmission unit (132) contained in a service application unit (13) connectable to the customer device (15) via a second telecommunications network (11) based on an Internet IP protocol; in response to the lost packet petition message from the first data transport stream, transmission of a second digital data stream that comprises at least one packet lost form the first digital data transport stream.

Abstract: A content request is sent (31) from a client (4) and the network routes (321) it to origin server (301) and mirrors (322) it to a transparent cache server (103). The transparent cache server (103) takes a decision on whether to deliver the content or not. If the transparent cache server (103) decides to deliver the content (33), it takes over the content delivery session setup between the client (4) and the origin server (301), impersonating and then disconnecting or triggering disconnection of the origin server (301). If the transparent cache server (103) is not delivering the content, due to cache failure, because the decision of the transparent cache server (103) is not to perform the delivery or because, being the decision of the transparent cache server (103) to deliver the content, the origin server (301) is still being connected, the content delivery session continues (34) between the origin server (301) and the client (4).

Abstract: A coding/transmitter device (11) includes a broadcasting module (12) in order to broadcast television to a plurality of STB receiver/decoder devices (15) via an IP/Internet network (14), so that the clients-subscribers are provided with a first UDP stream and a second UDP stream which includes identification data associated with data packets transmitted within the first UDP stream in order to provide functionalities such as reorganization of packets, detection of losses, requests for retransmission etc. without adding headers according to the RTP protocol, but with a reliability and capability of inserting additional data comparable to that provided by the RTP protocol.

Abstract: A method for authorising access to multimedia digital programmes with access control and broadcast by a broadcast server (11) to descrambling devices (13) through a communications network, in which access request messages are transmitted for a reduced period of time, to a scrambled multimedia digital programme from descramblers (13) to a licence server (12); comparison in the licence server (12) of the request messages received with a specific trust level associated with a predetermined credit level stored in the licence server (12) and in which each customer is assigned a credit level; if the comparison is positive, transmission of an access authorisation and descrambling key from the licence server (12) to the descrambler (13), and retransmission of the authorised request messages received to the broadcast server (11), when the multimedia digital programme is being played or has finished.

Abstract: A procedure to broadcast digital multimedia contents to subscribers, where a first digital data transport stream broadcast to subscribers from a head end (12) via a first telecommunications network other than a telecommunications network based on an Internet IP protocol is received in a customer device (15); transmission from a first retransmission unit (153) of a lost packet petition message to a second retransmission unit (132) contained in a service application unit (13) connectable to the customer device (15) via a second telecommunications network (11) based on an Internet IP protocol; in response to the lost packet petition message from the first data transport stream, transmission of a second digital data stream that comprises at least one packet lost form the first digital data transport stream.

Abstract: A procedure for broadcasting multimedia digital content to subscribers, in which a first transport stream of digital data is transmitted from a header source (12) through a first telecommunications network differing from a telecommunications network based on an IP internet protocol to subscribers and is received in a customer device (15); transmission from a first channel change unit (153) of a first channel change message to a second change unit (132) of a service application unit (13) connectable to the device (15) through a second telecommunications network (11) based on an IP internet protocol; in response to a channel change message received by the first change unit (153); transmission of a second digital data stream associated with the desired channel, which begins in a key frame stored in a second storage unit (133) of the server (13), in response to the reception of the first change message received in the second channel change unit.

Abstract: A multimedia digital data transmission device which may respond to a request message from a second segment of a second operational data stream in fast forward or rewind mode (trick mode), associated with a first data stream of a selected multimedia digital content transmitted from a client device (13) through a communications network (11) based on an internet protocol; in which the transmission device (12) comprises a data segmentation unit (16) which generates a second segment by means of a different coding or through extraction of a plurality of frames included in a specific number of first segments of the first data stream of a selected digital multimedia content, and in which the length of the second segment is equal to the length of a specific integer number of first segments.

Abstract: The present invention is related to a device for authorising access to data content protected by a control signal (CW) and delivered to a terminal over a network comprising an access network. The device is arranged for receiving a version of the control signal and further comprises processing means for processing the received version of the control signal and arranged for sending to the terminal an output signal derived from that processed version of the control signal. Said output signal enables the terminal to get access to the delivered data content protected by the control signal. The device is characterised in that it is operable in the access network.
