Abstract

Il sistema consente mediante un dispositivo "compositore" ed uno "scompositore", di poter comporre due segnali video (relativi a due diversi programmi televisivi) in un unico segnale "risultante". Ogni quadro di questo segnale risultante è costituito da un semiquadro del primo segnale e da un semiquadro del secondo segnale. Il segnale "risultante" (costituito dai due segnali video componenti) può essere trasmesso con un normale trasmettitore, su di un solo canale televisivo, ovvero può essere videoregistrato da un unico videoregistratore, su di una sola videocassetta.Lo "scompositore" consente di decomporre il segnale "risultante" (sia ricevuto via etere, sia riprodotto con un normale videoregistratore) nei due segnali video componenti e di selezionarne il preferito.APPLICAZIONI ED UTILITA': Trasmissione contemporanea di due programmi televisivi distinti, utilizzando un solo canale TV. - Videoregistrazione simultanea di due programmi su una sola videocassetta, dimezzando tempi di registrazioni, spese e volumi (per l'archiviazione).The system allows, by means of a "composer" and a "decomposer" device, to be able to compose two video signals (relating to two different television programs) in a single "resulting" signal. Each frame of this resulting signal consists of a half frame of the first signal and a half frame of the second signal. The "resulting" signal (consisting of the two component video signals) can be transmitted with a normal transmitter, on a single TV channel, or can be videotaped by a single video recorder, on a single video cassette. The "splitter" allows you to decompose the "resulting" signal (whether received over the air, or reproduced with a normal video recorder) in the two component video signals and to select the preferred one. APPLICATIONS AND UTILITIES: Simultaneous transmission of two distinct television programs, using a single TV channel. - Simultaneous video recording of two programs on a single videotape, halving recording times, expenses and volumes (for archiving).
