Fig 2. Details of the system used in this experiment.
The minimum communication delay was 20 ms, considering the typical performance of domestic communications. The minimum total communication delay was thus 70 ms, including the decoding and encoding times. TN = {0,20,50,100,150,250}ms, TE+TD≈50ms, Delay defined in this paper T is: T = TN+TE+TD = {0,70,100,150,200,300}ms, *Encoder/decoder unused when TN = 0.
