    Abstract: A method and system for the insertion of local signals, including digital media advertisements, into statistically multiplexed streams is presented. The rate control and timing information is computed and is used to specify the insertion time and rate parameters for digital advertisements. In one embodiment, a maximum bit rate over the advertisement duration is specified. The maximum bit rate may be constant or may vary in time, such that high bit rate portions of the advertisement are supported. High bit rate portions of the advertisements in different program streams may be staggered, such that the total bandwidth required does not exceed a maximum, but allowing for high bit rate portions of advertisements. Custom bit rate profiles for advertisements may also be defined, with the profiles being defined at a high granularity or a low granularity.

    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.

    Abstract: The present invention makes it possible to efficiently transmit data for statistical multiplexing which is required for control using statistical multiplexing. By utilizing private packets, respective encoding devices transmit encoding difficulties serving as the data for statistical multiplexing to a multiplexer (4) via the same transmission channels as encoded video data and audio data are transmitted. The multiplexer (4) conducts multiplexing processing on data supplied from the respective encoding devices at a first rate R1 larger than a transmission rate on a transmission channel of a subsequent stage, and outputs a transport stream (TSd) including the private packets to a statistical multiplexing computer. In addition, the multiplexer (4) conducts multiplexing processing on data obtained by removing the private packets, at a second rate R2 which is equal to the transmission rate on the transmission channel of the subsequent stage, and outputs a transport stream (TSm) which does not include the private packets to the transmission channel of the subsequent stage.
