Abstract: A control command, which has a command header sequence and a sequence of n parameters, is generated in a data source of a local network. The control command has a variable length defined by the data source. The control command is passed to the ring data line of the local network and is forwarded to a data sink. This data sink contains a control unit, a picture output unit, an interface and a memory, in which video data are stored. The video data can be read out and displayed on the picture output unit. The control command has n parameters of which the first m parameters are interpreted by the control unit. The number m is determined by the properties of the data sink and is independent of the properties of the data source. Using the m interpreted parameters, specific video data are read from the memory and are reproduced.

Abstract: In a method for calibrating or aligning a multistage selective amplifier including an oscillator circuit and at least one tuning circuit, the tuning voltages respectively necessary for aligning the respective tuning circuits to the required receiving frequency are calculated directly from a mathematical relationship between the respective tuning voltage and the oscillator voltage. In order to achieve this, a characteristic multiplicative coefficient and a characteristic additive factor for each tuning circuit are stored in a memory upon manufacturing or switching on the device. In order to select a desired receiving frequency, the respective stored values as well as an oscillator voltage are provided to an amplification circuit, which correspondingly amplifies the oscillator voltage by the multiplicative coefficient and the additive factor and then provides the resulting output value as a tuning voltage to the respective tuning circuit.

Abstract: A method for transmitting digital data over data lines between subscribers forming data sources and data sinks, being disposed in a network having a ring structure in particular and connecting a plurality of subscribers to one another, includes transmitting the data in a format specifying a clocked sequence of individual bit groups of equal length being subdivided into partial bit groups each forming a data channel for temporarily assigning each of the partial bit groups to two subscribers in the network for a data transmission. In order to increase the transmission capacity, the data channel or channels assigned to two subscribers in the network for a data transmission are freely selectable from the existing data channels, and the data channel or channels used for the data transmission are allocated to a certain data source and a certain data sink through an allocation specification, which can be defined prior to the data transmission through the use of a control command.

The region of a bit group reserved for the source data is subdivided into a plurality of partial bit groups of equal length. The source data assigned to each partial bit group are allocated to a certain data source/data sink as a function of the control data.

Abstract: A method for the common transmission of digital source data and control data between data sources and data sinks. The data sources and data sinks are subscribers in a communication network with a ring structure. The source data and control data are transmitted in a format which prescribes a pulsed sequence of individual bit groups of identical length. Specific bit positions in each of the bit groups are reserved for source data and control data. The transmission is in a continuous data stream synchronous with a clock signal. An arbitrarily large contiguous region of the bit positions can be reserved for the source data within a bit group for data which are transmitted in data packets. Each of the data packets has a start with a subscriber address and a defined length.

Abstract: A method for compensating for propagation time delays in a communication network includes connecting each of a plurality of subscribers to a ring feeder for a common transmission of digital source data and control data in a data stream synchronous with a clock signal. The source and control data are transmitted in a format prescribing a pulsed sequence of individual bit groups of identical length containing component bit groups each forming a data channel for source data or control data. At least two subscribers, which are connected at different locations to the ring feeder, receive source data that are transmitted by one of the subscribers on different data channels and are correlated with one another. Specific bit positions are reserved in each bit group for a numerical value relayed from subscriber to subscriber. The numerical value is always set by one of the subscribers to a fixed initial value and incremented by each following subscriber along the ring feeder.

Abstract: A method for transmitting digital data over data lines between subscribers forming data sources and data sinks and being disposed in a network having a ring structure and connecting a plurality of subscribers to one another with network segments each being formed between two adjacent subscribers, includes transmitting the data in the network in a format specifying a clocked sequence of individual bit groups of equal length, each including at least one partial bit group forming a data channel to be assigned temporarily to two subscribers in the network for a data transmission. A temporary allocation of the data channels for a data transmission between two subscribers takes place segmentally in the network, for optimal utilization of the data transmission capacity of the network only those network segments that are located between the applicable data source and the associated data sink are occupied for the particular data transmission.

Abstract: A method for common transmission of digital source and control data between data sources and sinks being connected by data lines, includes transmitting the source and control data in a format prescribing a clocked sequence of individual bit groups of equal length. In each bit group, there are one or more and in particular two control bits, which are used for the transmission of control signals. One control signal is assigned bitwise to the control bits of successive bit groups. A starting identification code which is identical for all of the control signals is provided at the beginning of each control signal.

Abstract: A method for determining the position of a network subscriber is used in a network having a ring structure with a plurality of network subscribers being connected to one another, including one network subscriber being used as a master. At the onset of network operation, the master generates a number that represents a subscriber's positional designation and stores it internally in memory. Beginning with the master, each network subscriber causes the network subscriber immediately following it in the ring structure to store a number in memory that likewise each represents its positional designation and that is raised by a number over its predecessor's own positional designation. This continues until an individual positional designation has been assigned to each network subscriber. The method may be used for individual and targeted communication with physically identical network subscribers, such as speaker boxes, as well as in stationary or mobile communications systems.

Abstract: A method for initializing a network for data transmission between a plurality of subscribers being connected to one another in ring-like fashion, includes sending a clock signal through the network in a continuous data stream, originating at a network position. In each subscriber, a process of locking onto the clock frequency is started after reception of the data stream, and the data stream is forwarded to the next subscribers in succession after locking on is completed. In order to speed up the initializing process, the arriving data stream is split into two identical streams at each subscriber, as long as it has not yet locked on. One of the streams is used for the locking-on process and the other of the streams is immediately forwarded to the next subscriber.
