Abstract :
In the framework of multiple description coding a condition to design generalised embedded multiple description scalar quantisers yielding embedded uniform central quantisers is proposed. In addition, a control mechanism that enables redundancy tuning between the descriptions at every distinct quantisation level is designed.
