The invention which is the subject of this application relates to the ability to utilize a receiver and processing means for received data in the reception of multiple transport streams of data. Processing components which are included in receiver apparatus are provided with the ability to only receive one transport stream of data at any one time. In the current invention, in order to present to the processing components in the receiver, one single transport stream, but still allow the receiver apparatus to receive multiple transport streams of data, there is provided a means of initially processing the received multiple streams of data which involves the steps of demultiplexing the data from the multiple transport streams, re-mapping the data, selecting packets of data in accordance with user and receiver selection criteria and then multiplexing the said selected packets of data into a single stream of data which can then be presented to the processing components.
