Abstract:
In a remodulator system, a generator of an output packet stream having a first rate, comprising:a source of a stream of input transport packets having a second rate; a source of additional packets; a multiplexer, coupled to the input transport packet stream source and the additional packet source, for generating the output packet stream; a source of a control signal, responsive to the first and second rates, for generating the control signal having a first state when an input transport packet should be inserted into the output packet stream and a second state when additional packets should be inserted into the output packet stream wherein the control signal source accumulates the amount of time the input transport packet stream is in advance of the output packet stream, and generates the control signal having the second state when the accumulated time is greater than a time duration of each output packet, and having the first state otherwise; and a multiplexer controller, coupled between the control signal source and the multiplexer, for conditioning the multiplexer to insert an input transport packet into the output packet stream when the control signal has the first state, and to insert an additional packet into the output packet stream when the control signal has the second state.
