Abstract: A network component (3d) for an optical network (1) is described, including a coupling device (2; 4, 5) for optical coupling of the network component (3d) to the optical network (1), the coupling device (2; 4, 5) having a receiving module (4) and a transmitting module (5); a first data processing device (8, 9) which is unidirectionally connected to the receiving module (4); a second data processing device (10, 11) which is unidirectionally connected to the transmitting module (5); the first data processing device (8, 9) being unidirectionally connected to the second data processing device (10, 11) for transmitting data to the second data processing device; a detection device (4) for detecting the network status; and a two-way switch (23) for switching of the input of the first data processing device (8, 9) between the receiving module (4) and the output (19) of the second data processing device (10, 11) as a function of the network status detected.

Abstract: A method is proposed for compressing a sequence of data elements and for decompressing it, which is used for loss-free, storage space-saving compression. In this connection, the data elements are stored in a compressed or uncompressed form depending on the correlation with preceding or subsequent data elements in the data element sequence. In particular, the method is used for the display in a freely programmable combination instrument in a motor vehicle. The data to be compressed are in particular image data.

Abstract: A method of data transmission from a data source to a data sink via a bus system. Run length encoding of the data to be transmitted is performed, where data units 1; 1′ having two data elements 2, 3; 2′, 3′ are used, the first data element 2 of which contains a repeat factor n of a datum D, and the second data element 3 contains the corresponding datum D; and at least one predefined repeat factor m in the first data element 2′ is defined as a flag for the presence of additional information ZI, where the second data element 3′ contains the additional information ZI.
