Remarques

Marque : "Zygma 2001".

"Zygma Projected Television is a picture ten times the size of the biggest direct viewing TV set. It is a dramatic difference in technique that creates a new sense of participation and involvement. A visual revolution of the space age at a price that is strictly down to earth. Zygma Teleprojection offers a new viewing experience. A screen ten times larger than usual receives a picture 4 1/2 feet (1.32m) high by 5 3/4 feet (1.75m) wide of supreme clarity beamed from 8 feet (2.54m) away. Conventional television recreates an image on the inside face of a picture tube. Zygma projects it into the face of a gently curved cinema-style screen that uses a new aluminium reflective material five times more efficient than the surfaces of the standard TV screen. The sound, too, is beamed from a wide range acoustic suspension speaker and reflected back so that it appears to come from the screen. [...] The essence of Zygma lies in the teleprojector. This space-age floor console receives broadcast signals just as a conventionel set does, but from then on things are different. The receiver houses three projector tubes, one for each primary color. Red, green and blue. The colours converge on screen, each re-assembling only its own part of the broadcast picture, but doing it so well that the combined result is superb. A high resolution, magnetically focussed electron beam and phospor target for maximum undistorted light output make a major contribution towards the peak performance Zygma provides. Taking the technicalities further, a low deflection angle produces a more linear picture, while a computer designed optical system ensures distortion free projection of pictures to screen. Maximum video colour performance is assured, and DC restired video is employed to improve contrast and prevent loss of detail in darker areas of the picture. Total colour decoding gives full colour reproduction. More than 50 people can view Zygma in comfort, yet it still has the intimacy for just one or two. [...] To make the most of that potential, the Teleprojector has been equipped with four input connectors : antenna input from external aerial ; video and audio input from a video recorder ; video input from a video camera or recorder ; audio input from a video camera or recorder. The Zygma Teleprojection system can project any pre-recorded video material when used in conjunction with the appropriate ancillary equipment. The systm also includes five output connectors : broadcast material, video and audio output to a video recorder ; video and audio output to a second video recorder ; audio output to a second video recorder ; video output for use with a monitor ; audio output for use with a monitor" (A giant step for television, Zygma teleprojection, London, Zygma Electronics Ltd, s.d.).
