A transport stream generating apparatus, a turbo packet demultiplexing apparatus, and methods thereof, the transport stream generating apparatus including: a Reed Solomon (RS) encoder to RS-encode turbo data, an interleaver to interleave the RS-encoded turbo data, a duplicator to add a parity insertion area to the interleaved turbo data, and a multiplexer to multiplex normal data and the turbo data processed by the duplicator to generate a transport stream. Accordingly, reception performance can be improved in an advanced vestigial sideband (AVSB) system.

L'invention porte sur: un appareil de production de flux de transport, sur un appareil de démultiplexage de paquets turbo et sur les méthodes associées. L'appareil de production de flux de transport comporte: un codeur RS (de Reed Solomon) de données turbo en données turbo RS; un entrelaceur des données turbo RS; un duplicateur d'adjonction d'insertion de parité aux données turbo entrelacées; et un multiplexeur multiplexant des données normales et les données turbo traitées par le duplicateur pour produire un flux de transport. On obtient ainsi des performances de réception améliorée dans un système AVSB (avancé à bande latérale résiduelle).
