摘要
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.;The invention relates to a local network having a plurality of subscribers, which are connected to one another through the use of an optical data line for transmitting audio, video data and/or control data. The subscribers, together with the optical data line, form a ring network.
