Method and devices for the transmission of data with transmission error checking

摘要

A method and device for detection of errors, in particular transmission errors, in data streams and/or data packets. A variable function is applied to data to be transmitted. The function is varied on the basis of time and/or the data itself, for example, by assigning an individual variation value to each of indices (such as a packet index). After having been varied, the data is subjected to error detection processes prior to transmission and after reception. Results of the error detection processes are compared to determine if the data has been transmitted properly.
