Statistical Multiplex - The allocated bit rate that an encoder requires is exploited. Video for each service is first sampled by the encoder and the results are mapped to the required quality of each service. The 'Multiplex Element Manager' then assigns the bit rate that each encoder uses for each service to use the total available bit rate for the group to maximum effect. The gains are huge. 5-6 services can be transmitted in the same bandwidth as 3 single path services whilst achieving the same and sometimes better quality of pictures.
