Digital video over an ATM network
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
This thesis describes the implementation of an ATM to STM-1 interface, designed to provide video conferences. The video encoder and decoder are working in an ATM network, where the ATM cells are transported in STM-1 frames over optical fibres.
The digital video information will be compressed from 166 Mbit/s to 34 Mbit/s or 17 Mbit/s depending on the motion compensated prediction algorithm is used. To eliminate redundancies in spatial domain the discrete cosine transform is applied.
The ATM adaptation layer is of type 1, which handles cell delay variation, cell loss and clock recovery. The ATM:s physical layer functions such as header error control generation and scrambling are performed before the cells will be mapped into STM-1 format.
