Abstract
A network access unit of a communications network includes: a source data receiver module to receive first source data representing video content and second source data; a network control module to receive link condition data and configuration data, calculate priority data based on the link condition data and the configuration data, use the priority data to generate a master schedule indicating a first coding and modulation scheme for a first layer of the first source data and a second coding and modulation scheme for a second layer of the first source data, wherein at least one of the coding and modulation schemes for a next sequence is fixed relative to a present sequence; a pre-coder module to pre-code the first source data using pre-coding schemes to generate sets of representation data; and an ACM module to associate the sets of representation data with the coding and modulation schemes.
