A method for processing a dual transport stream (TS) which is multiplexed from a normal stream and a turbo stream is provided for a digital broadcasting transmission/reception system. The digital broadcasting signal processing method includes encoding a dual transport stream (TS) which is multiplexed from a normal steam and a turbo stream; interleaving the encoded dual transport stream (TS); turbo-processing by detecting the turbo stream from the interleaved dual transport stream (TS), encoding the detected turbo stream, stuffing the encoded turbo stream into the dual transport stream (TS), and compensating a parity corresponding to the encoded turbo stream; and trellis- encoding the turbo-processed dual transport stream (TS). Accordingly, the digital broadcasting reception performance can be improved in diverse environments.
L'invention porte sur un procédé de traitement d'un double flux de transport (FT) qui est multiplexé à partir d'un flux normal et d'un flux turbo et est prévu pour un système d'émission/réception de radio diffusion numérique. Le procédé de traitement de signaux de diffusion numérique consiste à coder un double flux de transport (FT) qui est multiplexé à partir d'un flux normal et d'un flux turbo; entrelacer le double flux de transport codé; effectuer un traitement turbo en détectant le flux turbo à partir du double flux de transport entrelacé, coder le flux turbo détecté, bourrer le flux turbo codé dans le double flux de transport et compenser une parité correspondant au flux turbo codé; et coder en treillis le double flux de transport ayant subi un traitement turbo. La performance de réception de diffusion numérique peut être ainsi améliorée dans divers environnements.
