Abstract
A system and method for multi-source data communications includes a receiver configured to receive a first data stream from a first data source, such as a satellite. Associated with the first data stream is an instruction to the receiver that causes the receiver to receive a second data stream from a second data source. The second data source may be a different satellite beam from the first satellite, a second satellite, or a terrestrial source. A receiver processes the first and second data streams to produce an output. The second data stream may be inserted into the first data stream at a predetermined point. Alternatively, the first and second data streams may be processed concurrently and combined by an output device. The first and second data streams may be identical data types, or differing data types.
