Paper Abstract

The asynchronous transfer mode (ATM) appears as the standard protocol for image and video transmission. There is virtually no bandwidth limitations neither a restricted size of operating area. However, the main problem stands in the non-secured transmission when ATM native applications are implemented. This induced a new way of encoding images where the redundancy is generated into the CoDec. In this paper, we present the Mojette transform that generates the redundancy at the higher level of the coder in order to safely transmit image data. BLock and wavelet implementations associated with the Mojette transform are presented and compared not only from the coder point of view but for the source and the channel characteristics. For this specific case we also present the asynchronous Mojette reconstruction. An adapted object oriented model has been developed accordingly.
