    摘要: Methods and systems for delivering decrypted Internet Protocol (IP) packets are described. The method for delivery comprises steps of receiving a request from an application for IP packets associated with a first IP address/port pair; receiving IP packets associated with a different IP address/port pair; extracting decryption information from the IP packets associated with the different IP address/port pair; decrypting the encrypted IP packets associated with the first IP address/port pair based upon the extracted decryption information; and transmitting the decrypted IP packets associated with the first IP address/port pair to the application. The decryption information may include decryption key(s) and/or properties/parameters and may be independent of the application.

    摘要: An apparatus for providing mobile broadcast service protection may include a processor. The processor may be configured to receive an indication of device groupings defining at least a first group of devices and a second group of devices in which the first and second groups are defined on the basis of a device characteristic, communicate a first security key providing access to a first message stream associated with a mobile broadcast service to the first group of devices, and communicate a second security key providing access to a second message stream associated with the same mobile broadcast service to the second group of devices. Methods and computer program products corresponding to the apparatus are also provided from the perspective of a network device and mobile terminal.

    摘要: A terrestrial digital video broadcasting (DVB-T) network is used to transmit IP datagrams to receiving devices using multiprotocol encapsulation (MPE). MPE datagram sections and, if forward error correction (FEC) is used, MPE-FEC datagram sections are transmitted in time-sliced bursts. Time slicing parameters specifying a minimum time between bursts and bit rate output of a receiving device time slicing buffer can be used to help improve power saving and improve quality of service.

    摘要: According to an embodiment of the invention, an apparatus includes a decoder configured to decode transmission parameter signaling data from a signal, the signal including the transmission parameter signaling data on a lower level than a level on which service information is included; and a determiner configured to determine from decoded transmission parameter signaling data if the signal carries time-sliced elementary streams and configured to determine from the decoded transmission parameter signaling data whether the signal has a forward error correction framing structure, wherein the apparatus is a receiver and is configured to operate in a network. The apparatus further includes a controller configured to disregard a signal in response to determining that the signal does not carry time-sliced elementary streams.

    摘要: A method comprises detecting zapping to or from one or more services; determining whether the zapping includes termination of a password-protected service; and sending a trigger message (248, 256, 262) only if the zapping includes termination of a password-protected service (X, Y, Z). In one embodiment, the trigger message is sent to a smartcard (SC). In one embodiment, the password-protected service is password-protected for parental control. In one embodiment, the method further includes requesting a password when the zapping includes zapping to a password-protected service. In one embodiment, the password-protected service is a pincode-protected service.

    摘要: A multiprotocol encapsulation (MPE) encapsulator (6) receives or generates a copy or partial copy (10′) of service information data (10) and generates associated forward error correction (FEC) data. In addition to transmitting service information data in a conventional way via a first set of channels, the MPE encapsulator transmits the copy 10′ and the associated FEC data via a second set of channels.
