A network access unit includes: a source data receiver module adapted to receive multiple first source data representing respective video content and second source data representing broadband data content; a network control module adapted to receive link condition data and configuration data, calculate priority data based on the link condition data and the configuration data, and use the priority data to generate a master schedule including program data indicating that some but not all of the multiple first source data are to be transmitted; a pre-coder module adapted to pre-code respective first source data using respective pre-coding schemes to generate respective sets of representation data, if the program data is determined to indicate that the respective first source data is to be transmitted; and an ACM module adapted to associate, for each first source data indicated for transmission, the respective sets of representation data with respective coding and modulation schemes.
