    摘要: An interface link layer device (1) of an interface which allows the interconnection of different networks to build a distributed network according to the present invention routes complete data packets directly to another interface link layer device (1) that serves the destination via uplink means (10, 11, 12, 13, 14, 17) to accept a data packet from a first data bus (2) that has a predetermined destination on a second data bus and to transmit it via said transmission path (3) to said other interface link layer device (1), and downlink means (20, 21) to output data packets received via said transmission path (3) from one other interface link layer device (1) to a predetermined destination on the first data bus (2). Furtheron, the interface link layer device according to the present invention introduces the concept that not all packets have to be transmitted via the interface on basis of an appropriate acknowledge code and response packet generation of an acknowledge/response means (18, 19) included in the interface link layer device. The present invention is in particular applicable to build up a disrtibuted network on basis of several IEEE 1394 networks that are interconnected via an interface consisting of a coaxial cable.

    摘要: An interface link layer device is connected in-between a first sub network and a long delay link to which at least one second sub network is connected. The interface link layer device comprises at least two storage areas, whereby new configuration data received via the long delay link is written to one of the storages to simulate the devices of the second network within the first network. In case a self ID phase is initiated as long as the configuration information is not complete yet, the respective other storage area is accessed. In case a self ID phase is initiated as soon as or after the new configuration data is complete, the storage area to which the new configuration data has been written is used for setting up the self ID packet.

    摘要: The present invention relates to a carrier recovery means in particular in a channel decoding unit or a digital demodulating unit of a digital broadcasting receiver. The inventive carrier recovery means comprises at least first and second phase error detecting means (2, 4) in which the first phase error detecting means (2) generates a robust phase error signal based on a digital input signal. Said second phase error detecting means (4) receives said robust phase error signal and generates therefrom a frequency sensitive phase error signal which is representative for the frequency error or frequency offset between the frequency of the receiver and the frequency of the carrier of the received digital input signal. The frequency sensitive phase error signal is then used to reduce at least the frequency error with respect to the received digital input signal to enable locking of the receiver to the carrier of the digital signal.

    摘要: According to the invention, information from a differential decoder (1) receiving the MSB of the in-phase component and the MSB of the quadrature component is used to derotate the LSBs of the in-phase component and the LSBs of the quadrature component into the first quadrant with a rotator (2). Then only one quadrant is demapped by a single quadrant demapper (3). Thereby, the look-up table necessary for the demapping circuit is reduced considerably. The output signal of the QAM de-mapping circuit is build from the demapped LSBs of the in-phase and quadrature components output by the single quadrant demapper (3) and the outputs of the differential decoder (1).

    摘要: A method to perform a cycle synchronization between interconnected sub-networks, in which a reference node connected to one of the sub-networks transmits a respective cycle time information to cycle masters of all other sub-networks at recurring time instants, and the cycle masters of all other sub-networks adjust their cycle time accordingly. An adjustment of the cycle time within a cycle master is performed by determining a first time interval (t1, t1′) in-between two receptions of cycle time information from the reference node with an own clock, determining a second time interval (t2, t2′) in-between two corresponding transmissions of cycle time information from the reference node on basis of the received cycle time information, comparing the first time interval (t1, t1′) and the second time interval (t2, t2′), and adjusting the own cycle length according to the comparison result.
