Abstract: According to an exemplary embodiment of the present invention, an interactive information system for providing user data is stated, in which a control unit pre-processes data selected from raw data received from at least one individual data source. The selected pre-processed data is then transmitted to a user interface device where it is further processed and interactively displayed. User data is transmitted as an array of data points to the user interface device via a data packet of a fixed maximum size. User data may be transported to the user interface device, even in the case if the network connection between the control unit and the user interface may be very bad, i.e. the network connectivity and/or the bandwidth are very low.

Abstract: According to an exemplary embodiment of the present invention, a data communication is provided, in which data is encoded into a data package of a fixed maximum size and transmitted to a receiving station. The receiving station decodes and further processes the data package on the basis of a decoding procedure in combination with processing information stored in the receiving station. The data belongs to a particular data group and a processing information relates to the particular data group.
