A data transport system for transporting data between a server (21) and a client receiver (27) over a network (23) includes a receiving proxy cache (25) coupled to a client receiver (27) via a reliable connection (29), such as a cable connection. The majority of data is transported from the server (21) to the receiving proxy cache (25) over an efficient data transmission channel (41). The receiving proxy cache (25) verifies the status of the data transmitted over the efficient channel (41). If there is an error in the data transmission, a portion of the data associated with the error is retransmitted from the server (21) to the receiving proxy cache (25) over a reliable data transmission channel (43). The complete data at the receiving proxy cache (25) is delivered to a client receiver (27) over a reliable connection (29).
