    摘要: 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.

    摘要: 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.
