US Patent 7805655 Turbo stream processing device and method

A turbo stream processing device and method. A turbo stream processing device includes a turbo stream detector to receive a dual transmission stream in which a turbo stream and a normal stream are multiplexed, and to detect the turbo stream; an outer encoder to encode the turbo stream; an outer encoder to interleave the turbo stream which is encoded at the outer encoder; and a turbo stream stuffer to reconstruct the dual transmission stream by stuffing the interleaved turbo stream into the dual transmission stream. Accordingly, the reception performance can be enhanced by more robustly processing the turbo stream in the dual transmission stream.
