Abstract: A digital network for communication between a plurality of subscribers by means of streaming data comprises at least one subscriber that is a transmitter, and at least one subscriber that is a receiver. At least one transmitter is adapted to be activated, and then to feed streaming data in the form of broadcasts or multicasts into the network. Furthermore, at least one receiver is adapted to be activated, and then to select from the network streaming data that are compatible with its data formats, and to read the selected streaming data from the network.

Abstract: Network devices of a digital network for communication between a plurality of devices have a source for transmitting data into the network, and sinks for receiving data from the network. Managers (logical controllers) to which priorities are assigned in a hierarchical order manage connections between sources and sinks. Before setting up a connection, a manager first queries a negotiation administrator to obtain a right to negotiate with other managers and to set up connections. When all other managers having higher priorities also have granted the connection, the manager connects sources and sinks.

Abstract: A dissemination system for satellite broadcasting comprises a satellite receiving antenna for receiving satellite signals, receivers for demodulating the signals received by the antenna, and a line system for relaying the signals to a plurality of subscribers, in which the receivers are assigned to the satellite receiving antenna in close spatial proximity, and only demodulated or decoded signals are relayed to the subscribers by means of the line system.

Abstract: A communication system, network, interface, and port architecture are provided for transporting different types of data across a network. The network can be arranged by connecting the ports in a daisy-chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol, and nodes among the network can use a recovered clock from the bitstream to drive the transmitter and create a synchronous network even thought the network can receive Ethernet packets which are typically targeted for an asynchronous network. Non-compliant data, such as Ethernet data, can be sent as packets within a frame structure. The frame is synchronized to Ethernet coding violations used to signal the beginning of each frame, and each packet can be immediately followed by a packet coding violation. The frame and packet coding violations are represented as a sequence of 4B/5B codes that are not valid codes and, therefore, not present as Ethernet encoded data.

Abstract: An apparatus for the detection of information expected to be present in a defined data block of a RDS data flow transmitted as a predetermined number of groups which periodically follow one another, with a radio receiver tuned-in one after the other to a number of senders to be tested and whose RDS decoder is synchronized with the RDS data flow of the respective tuned-in sender. A running counter is provided having the frequency of the RDS data cycle and which is respectively reset upon reaching a count status corresponding to the period of a number of groups.

Abstract: For the tuning of a broadcast radio receiver to a transmitter of a certain type of program using RDS information firstly the broadcast radio receiver is tuned to any convenient transmitter, which is transmitting a program, which is in accordance with the wishes of the listener. The PTY information retrieved from the RDS data of such transmitter is stored by operation of an associated control element in order to set a filter, whose filter condition is the agreement with such PTY information. For the following tuning of the broadcast radio receiver to another transmitter, as for example by means of a search sweep, such transmitter is only considered to be suitable for reception if it fulfills the filter condition.
