    摘要： A media access control (MAC) layer controller can manage base layer data and enhancement layer data in a layered modulation system. The MAC layer controller can process both base layer data and enhancement layer data and map the encoded symbols to a layered modulation constellation when both are present. If data for one of the layers terminates, then the MAC layer controller can generate and supply predetermined stuffing data to the layer lacking additional data. The MAC layer controller can send a control signal to the physical layer hardware to cause the hardware to map the layered signals having the stuffing data to a modified signal constellation. The MAC controller can also generate an overhead message that indicates the occurrence of the stuffing data. The receiver can receive the overhead message and can use the information to configure the receiver for the layered modulation constellation or the modified signal constellation.

    摘要： Provided is a method and system for enhancing acquisition latency in a communications network. The method includes identifying control information associated with transmitted information and fragmenting the identified control information. Each fragment of control information is then associated with a corresponding transmission unit of the transmitted information. This process facilitates independent decoding and processing of the control information, which is embedded within physical layer packets.

    摘要： Provided is a method and system for transmitting information. The method includes determining stream length information for at least one data stream to be transmitted and associating the stream length information with a system parameter message. The system parameter message including the associated stream length information is transmitted separately from the data stream. This process facilitates de-multiplexing of individual streams and the processing of stream data even if one or more individual streams are received in error.
