| description | A digital broadcasting transmitter, a turbo stream processing method thereof, and a digital broadcasting system having the same. The digital broadcasting transmitter includes a first compressor, forming a normal stream by compressing audio and video signals in a first compression format, a second compressor, forming a turbo stream by compressing the audio and video signals in a second compression format, a transport stream (TS) constructor, compressing the turbo stream in an H.264 format and forming the dual transfer stream by multiplexing the normal stream and the turbo stream, and a TS processor, robustly processing the dual transfer stream transmitted from the TS constructor, thus enhancing the transmission efficienc.
L'invention concerne un émetteur de radiodiffusion numérique, un procédé de traitement de flux turbo associé, ainsi qu'un système de radiodiffusion numérique présentant ledit émetteur. L'émetteur de radiodiffusion numérique comprend un premier compresseur, formant un flux normal par compression de signaux audio et vidéo dans un premier format de compression, un second compresseur, formant un flux turbo par compression des signaux audio et vidéo dans un second format de compression, un constructeur de flux de transport (TS), compressant le flux turbo dans un format H.264 et formant le double flux de transfert par multiplexage du flux normal et du flux turbo, ainsi qu'un processeur de TS, traitant de manière robuste le double flux de transfert transmis par le constructeur de TS, améliorant ainsi le rendement de transmission. |
