A digital broadcasting system includes: a transmission stream generator multiplexing a normal stream and a turbo stream to generate a dual transmission stream; a transmitter inserting a supplementary reference signal (SRS) into the dual transmission stream, processing the turbo stream to reconstitute the dual transmission stream, and outputting the reconstituted dual transmission stream; and a receiver receiving the reconstituted dual transmission stream and decoding the normal stream and the turbo stream to restore normal stream data and turbo stream data. Thus, reception performance of a digital broadcasting signal can be efficiently improved.
L'invention porte sur un système de diffusion numérique comprenant: un générateur de flux de transmission multiplexant un flux normal et un flux turbo pour générer un double flux de transmission; un émetteur insérant un signal de référence supplémentaire (SRS) dans le double flux de transmission, traitant le flux turbo pour reconstituer le double flux de transmission et générant le double flux de transmission reconstitué; et un récepteur recevant le double flux de transmission reconstitué et décodant le flux normal et le flux turbo afin de restaurer les données du flux normal et du flux turbo. On peut ainsi améliorer efficacement la performance de réception d'un signal de diffusion numérique.
