Several aspects of the coding of video services in an ATM network environment have been studied. Variable Bit Rate (VBR) coding is discussed and the conditions for its effective application are explained. A method for the synchronization of VBR coded video services under the constraints of cell delay jitter is proposed. The role of the input buffer at the decoder side is explained, and the size is calculated for VBR connections. The influence of cell loss on picture quality is discussed and it is explained how cell loss can be concealed using a layered coding model.
