Abstract
A method and apparatus to create and transmit transport multiplexes comprising one or more levels of service over a network. In one embodiment, the level of service comprises high definition (HD) content or programs, and the transmitted multiplexes are distributed over a plurality of downstream RF carriers in a cable network simultaneously. A head-end architecture for performing the multiplexing and distribution of multiple HD programs over the multiple carriers (i.e., in a “wideband” configuration) is disclosed. CPE having one or more wideband tuners is also disclosed, the CPE being adapted to receive the multiplexed HD content from the various RF carriers, and demultiplex it in order to permit decoding and subsequent viewing by the user. The use of multiple HD source programs with the multiplex advantageously provides for enhanced statistical multiplexing by providing a larger “pool” of constituent inputs and available carriers.
