Talaria projector

Talaria was the brand name of a large-venue video projector from General Electric introduced in 1983.

Color display is accomplished in one of two ways: The single lens color projector (PJ5000 line) use dichroic filters to separate the white light of the xenon bulb in two channels, Green and Magenta.

RGB color separation and processing is obtained using vertical wobbulation of the electron beam on the oil film to modulate the green channel and sawtooth modulation is added to the horizontal sweep to separate and modulate Red and Blue channels.

[2] In early models (PJ5000), the light source was a 650 watt xenon bulb (sealed beam) similar to the units in modern 35mm film projectors, and produced 250 lumens at a 75:1 contrast ratio.

[4] The later LV series had an optional "Multiple Personality" (MP) module that would allow the projector to display various resolutions and scan rates produced by computers of the time.
