ABSTRACT:
A method for the transmission of line-oriented data sets. This method employs two data set structures which keep the images of the data sets at different time stages and which are filled alternatingly with the data sets. The method allows to determine updates of the data sets and avoids re-transmission of old information. In particular, moved lines are detected in a very effective manner. As a result, high update rates with low amounts of transmitted data are achieved. The method is suitable for local terminal sessions employing text or raster graphic terminals, which have to be operated from a remote site.
