1. An ATM cell-based method of transmitting data from an application, comprising the steps of: dividing the date across two or more of the cells;incorporating in a payload of each of the cells, error correction information for correcting the divide data in each of the cells individually depending on the application;transmitting the cells to a destination;performing error detection and correction on the divided data in each cell individually;recombining the corrected divided data; anddetecting uncorrected errors in the recombined data.2. Apparatus for a transmitting side of a cell-based system for transmitting date for an application, comprising: means for supplementing the data with error detection information;means for dividing the supplemented data across to or more of the ATM cells;means for incorporating within a payload of each cell error correction information; andmeans for transmitting the cells.3. Apparatus for a receiving side of an ATM cell-based system for transmitting data comprising: means for cells each comprising a portion of the data and comprising error correction information in a payload of the cells;means for correcting errors in the received cells individually dependent on the application using the error correction information;means for combining the portions of the data contained in the corrected cells;means for detecting errors in the recombined data; andmeans for processing the errors detected in the recombined data.4. Software stored on a computer readable medium for carrying out the steps of: receiving data transmitted in an ATM cell-based form from an application, the data being divided across two or more of the ATM cells, the cells incorporating in a payload of each of the cells error correction information for correcting the divided data in each of the cells individually depending on the application;performing error detection and correction on the divided data in each cell individually, the correction being dependent on the application;recombining the corrected divided data; anddetecting uncorrected errors in the recombined data.5.
