    摘要: A method for encapsulating at least one data packet includes fitting at least one data packet into at least one column of an application data table of an array that also includes a coding data table having at least one column. Then, at least one remaining column of the application data table is filled with padding, and coding data is fit into at least one column of the coding data table of the array. At least one column of coding data is punctured based upon a comparison of a bit rate of incoming data packets and a threshold bit rate, with at least one column of coding data remaining after puncturing the column(s) of coding data. And after puncturing the column(s) of coding data, the data packet(s) in the column(s) of the application data table, and the at least one remaining column of coding data, are encapsulated.

    摘要: A time slicing digital broadcast system includes a dynamic handover process switching a handheld terminal receiving services in a first signal to a second signal providing the same services, while roaming among cells in the digital broadcast system. The terminal takes into account the varying intervals between bursts in the current cell and the target cell. The terminal identifies possible handover signals from a MPE/FEC frame in a data stream. A table in the MPE/FEC frame transmitted once on each transport stream contains the mapping of the real-time handover signaling to the handovers that are possible from signals that are transporting the actual transport stream. The table contains a calculated retune interval specifying the guaranteed interval for the MPE/FEC frame. In another embodiment, the MPE/FEC frame contains MAC addressing bits in the MPE section for real-time parameters in time slicing. The bits may be converted into signaling scenarios for guaranteed handover time.
