Abstract: In a method, an apparatus and a computer program product for service decomposition in IP-broadcast networks, a full service bundle is detected within a first transport stream protocol having a plurality of broadcast packets corresponding to respective broadcast services. The respective service identifiers of the plurality of broadcast packets are evaluated, and the full service bundle is decomposed to create a plurality of decomposed broadcast packets on the basis of the service identifiers. For at least one same service identifier the corresponding plurality of decomposed broadcast packets is sent with the first transport stream protocol as a main service bundle, and for at least one remaining same service identifier the corresponding plurality of decomposed broadcast packets is sent with a second transport stream protocol as a sub service bundle. The second transport stream protocol contains synchronization information of the first transport stream protocol.

Abstract: In a satellite ranging system predetermined bit sequence or group of bit sequence in a transport stream, which is a digital signal are used to generate trigger signals on the basis of which the delay introduced into the transport stream by the travel path from a satellite ground station to the satellite and back or to another satellite ground station is determined allowing a calculation of the distance between the ground station(s) and the satellite. The predetermined bit sequence or group of bit sequences may be inserted into the transport stream at the uplink site, for example as a specific payload P. In order to avoid insertion of additional packets the transport stream or part of it may be used as a predetermined bit sequence.

Abstract: The invention refers to an apparatus for generating a reference frequency depending on a timing information extracted from a data stream. In order to generate a carrier frequency in a user station of a satellite TDMA network at low costs which is accurate and stable and which meets stringent phase noise requirements, it is suggested to use at least one free-running oscillator. The frequency deviation with regard to the timing information extracted from the data stream is estimated by an estimation means. At least two oscillation signals are derived from the at least one oscillation means and are linked together by a linking means yielding said reference frequency. A frequency correction value is applied to at least one of the oscillation signals such that the timing information given by the reference frequency corresponds to the timing information extracted from said data stream.

Abstract: The present invention relates to a device (1) that can be used to connect a cable (10). The connector includes a contact matrix (3) and the cable includes electrical conductors (10a-10d). The matrix elements of the contact matrix (3through-passing channels (3a-3d) in which the conductors (10a-10d) have been placed and the ends of said conductors applied to the outlet ends (3oa-3od) of the channels. The conductor ends are each applied electrically to a contact receiving device through the medium of an electrically conductive and elastically resilient material.
