system of composition of two video signals into a single output video signal to allow the simultaneous transmission (or videoregi form)with a single transmitter (vcr) and successes - it's decomposition of the signal, resulting in the two video signals to allow the use of components.

摘要

the system is used by a device "composer" and a "scompositore", can compose two video signals (on two different tv programmes) in a single signal "result".every part of this signal resulting is a semiquadro of the first signal and a second signal semiquadro.the signal "resulting" (consisting of the two video signals components) can be forwarded with a normal transmitter, on a single television channel.or may be recorded on a single machine, on a single tape.the "scompositore" allows us to break down the signal "resulting" (both received wireless signals.it is played with a normal vcr) in the two video signals and to select the preferred components.applications and utility: simultaneous transmission of two television programmes: using only one channel.- video simultaneously two programmes on a single tape, cutting time of recording costs and volumes (for the record).
