The present invention provides methods and apparatus for reconfiguring protocol data for a multiplexed data stream which is reduced to carry fewer services for cable-side transmission in a cable television plant or the like. More particularly, the present invention provides methods and apparatus for reconfiguring protocol data for a desired combination of data streams contained within an incoming high data rate multiplexed data stream, such as a high data rate Quadrature Phase Shift Keying (QPSK) modulated multiplexed data stream, when the incoming multiplexed data stream is reduced.

Methods and apparatus for reconfiguring protocol data when reducing multiplexed data streams

A re-multiplexer module for use in a packet processing system used in cable television headend devices generates two or more output streams from two or more MPEG input transport streams. The re-multiplexer module includes an input processing portion that receives a plurality of input data streams containing packet data, a plurality of packet buffers to store the packet data, an output processor that selectively multiplexes the data packets in the packet buffers, and a host processor that controls the operation of the input processing portion and the output processing portion.

MPEG re-multiplexer having multiple inputs and multiple outputs

The present invention provides methods and apparatus for creating a Program Association Table (PAT) for a reduced portion of a multiplexed data stream, when the multiplexed data stream has been reduced, for example, to carry fewer services over a cable television plant. More particularly, the present invention provides methods and apparatus for creating a PAT for a desired combination of multiplexed data stream subgroups contained within an incoming data stream, when the incoming multiplexed data stream is reduced. The invention enables a new PAT to be output which correctly corresponds to the services in a reduced data stream (e.g., for cable-side transmissions). The present invention is particularly useful when reducing high data rate satellite television data streams for cable-side transmission.
