CA 2624399

A digital broadcasting transmission system, and a signal processing method thereof, includes a parity area generating unit preparing a first area for parity insertion with respect to a dual transport stream (TS) which includes a normal stream and a turbo stream as multiplexed, a first interleaver interleaving the dual TS which is transmitted from the parity area generating unit, a turbo processing unit detecting the turbo stream from the interleaved dual TS, exclusively encoding the detected turbo stream for turbo-processing, and stuffing the encoded turbo stream into the dual TS, a deinterleaver deinterleaving the dual TS which is processed by the turbo processing unit, and a transmitting unit transmitting the dual TS which is processed at the deinterleaver.

La présente invention concerne un système d'émission de diffusion numérique et un procédé de traitement de signal associé. Ce système comprend une unité de génération de zone de parité préparant une première zone destinée à introduire une parité par rapport à un flux de transport dual (TS) qui comprend un flux normal et un turboflux tel que multiplexé, un premier entrelaceur entrelaçant le flux de transport de dual qui est émis à partir de l'unité de génération de zone de parité, une unité de traitement turbo détectant le turbo flux du flux de transport dual entrelacé, codant exclusivement le turboflux détecté pour un traitement turbo et plaçant ce turboflux codé dans le flux de transport dual, un désentrelaceur désentrelaçant le flux de transport de dual qui est traitée par l'unité de traitement turbo et une unité d'émission émettant le flux de transport dual traité au niveau du désentrelaceur.
