Title: (DE) SIGNALVERARBEITUNGSSYSTEM FÜR EIN GROSSBILDFERNSEHSYSTEM.
(EN) SIGNAL PROCESSING APPARATUS FOR A WIDESCREEN TELEVISION SYSTEM.
(FR) APPAREIL DE TRAITEMENT DE SIGNAUX POUR SYSTEME DE TELEVISION GRAND ECRAN.
Abstract:
(EN) In a widescreen signal encoding system for a television-type signal, side panel chrominance information (45, 46) is not subjected to time compression in an overscan region such as a horizontal overscan region containing time compressed (30) low frequency side panel luminance information. Both low and high frequency side panel chrominance information (I, Q), and high frequency side panel luminance information (YH), modulate (50, 55) an auxiliary subcarrier.
(FR) Dans un système de codage de signaux grand écran pour un signal de type télévision, les informations de chrominance (45, 46) des panneaux latéraux ne sont pas soumises à une compression temporelle dans une région d'analyse dépassante telle qu'une région d'analyse dépassante horizontale contenant des informations de luminance des panneaux latéraux, de basse fréquence, comprimées (30) en temps. Les informations de chrominance (I, Q) des panneaux latéraux, à la fois de basse et de haute fréquences, et les informations de luminance (YH) des panneaux latéraux, de haute fréquence, modulent (50, 55) un sous-porteur auxiliaire.
