<p>A data distribution system for providing data from a plurality of data sources to a broadcast data receiver is disclosed. The receiver (22) is connected to a plurality of data feeds (24, 26, 28, 30) and in turn switching means (32) which allows the switching of data sources (34, 36, 38, 40) which are to be connected to the data feeds (24, 26, 28, 30) in response to a user selection via the broadcast data receiver (22) and each of the data feeds (24, 26, 28, 30) are arranged such that at least part of the data signal is up converted and then down converted in frequency using processing components which allow each data feed to be used to process and transmit the required data signal at that time whilst minimising the complexity of the data feed processing means.</p> |
