Abstract:
1. A method of statistically multiplexing first services and second services in a group, comprising: obtaining a measure of required bandwidth for the first services, the first services comprising pre-encoded services; determining an available encoding bandwidth for the second services from a group bandwidth for the first and second services using the measure of required bandwidth; allocating an encoding bit rate to each of the second services based on the available encoding bandwidth; encoding each of the second services in accordance with the encoding bit rate thereof; and multiplexing the first services with the second services as encoded, wherein the measure of required bandwidth comprises a sum of weighted transcoding need parameters for the first services, and wherein the available encoding bandwidth is determined using a function of the sum of weighted transcoding need parameters, the group bandwidth, a sum of weighted encoding need parameters for the second services, a sum of minimum bit rates for the second services, and a maximum encoding bandwidth.
