Title
(EN) TV SIGNAL PROCESSING DEVICE
(FR) APPAREIL DE TRAITEMENT DE SIGNAUX DE TELEVISION
Abstract
(EN)
A device for processing TV signals to transmit them, wherein the TV signals are divided with a horizontal scanning line as a unit, the video signals between the consecutive two horizontal scanning periods are compared, and when part or whole of the video signals are different, the video signals Vx of different portions only are transmitted through TV signal transmitters (3, 4, 7A, 7B), video signals Vx are mixed to, superposed on, substituted for, or calculated with, part or whole of the video signals Vn-1 of one horizontal scanning period before by the TV signal receivers (25, 26, 27, 28) using the transmitted TV signals, in order to reproduce perfect video signals among the horizontal scanning periods.

Appareil de traitement de signaux de télévison avant leur émission, dans lequel les signaux de télévision sont divisés avec une ligne de balayage horizontale en tant qu'unité, les signaux vidéo entre deux périodes de balayage horizontales consécutives sont comparés, et lorsqu'une partie ou la totalité des signaux vidéo est différente, les signaux vidéo Vx de parties différentes uniquement sont émis par l'intermédiaire d'émetteurs de signaux de télévision (3, 4, 7A, 7B), les signaux vidéo Vx sont mélangés, superposés ou substitués à une partie ou à la totalité des signaux vidéo Vn-1 de la période de balayage horizontal précédente par les récepteurs de signaux de télévision (25, 26, 27, 28) utilisant les signaux émis, afin de reproduire des signaux vidéo parfaits parmi les périodes de balayage horizontal.
