Dave Jones Colorizer in Experimental Television Center Studio System Manual Tools
David Jones designed and built the Jones Six Channel Colorizer for the Residency Program at the Experimental Television Center; the device was developed in 1974 and 1975 and funded by a grant from the New York State Council on the Arts. The multi-functional image-processing unit accepts up to six black-and-white video signals and assigns independent hue and intensity per channel; controls include gain, pedestal, polarity, saturation, clip level, keying with any channel selectable as clip source, hard/soft edge control and additive or diode mixing, and most parameters are voltage-controllable including high-frequency control voltages.

Experimental Television Center Studio System Manual - Keying Tools
Two manual sections from the Experimental Television Center Studio Manual: Keying Process by Matthew Schlanger (c. 1984) and Keyers by Sherry Miller Hocking and Richard Brewster with Peer Bode, Hank Rudolph and Matt Schlanger; both appear in the 1980 and 1986 studio manuals. The text defines keying as mixing two video signals under control of a clip reference, explains synchronization of vidicon tubes/CRTs across 525-line frames and 262.5-line fields and notes a horizontal line frequency of 15,750 Hz. It describes three-input luminance keyers with VCA channels A and B, clip-level thresholds, internal versus external keying, and wipes using an externally synced oscillator.

Jones Frame Buffer in Experimental Television Center Studio System Manual Tools
The Jones Buffer is a black-and-white image buffer that operates standalone or under Z-80 computer control; front-panel controls allow real-time digitization, single-page grab/store and a keyer-like selective storage between live and stored signals. Memory totals 128,000 bytes (256×256 resolution yields 16 pages) and the buffer outputs a digital signal converted to analog; video I/O is routed via a matrix with two inputs (video and clip) and one output. In stand-alone mode it supports software such as STROBE64 and TESPNEW and can be routed with the CAT buffer; in computer mode it requires buffer-specific programs (e.g., NEWGRAB) and occupies the Z80 and D+7A, preventing CAT use.
Jones Keyer in Experimental Television Center Studio System Manual Tools
Richard Brewster, c.1976, documents Jones Keyers as hard-edge luminance keyers in the Sequencer case, describing I and II with two VCA channels, a clip channel, and voltage-controllable parameters accepting ±5 V signals. The manual includes step-by-step operating instructions. Keyer III is a hand-wired prototype with VC jacks for Ch. A and C; Keyers IV and V are three-input VC keyers that use Ch. C as the clip input, employ a BAL control in place of separate pedestals, and have manual-only On/Off and Normal/Reverse controls.
Jones Sequencer in Experimental Television Center Studio System Manual Tools
Technical documentation for the Jones 8 Input Sequencer, an eight-input, one-output voltage-controllable switcher that operates in sequence, binary (three-bit) and manual modes; it can process video signals or ±5 V control/audio/shape signals via front-panel mini-jacks. The entry details front-panel controls and indicators (including pushbuttons, pedestals and switches), sequence/count and sync inputs, sync modes for below and above 60 Hz (including a 60-sync option), interaction with external oscillators and the Analog Control and Image Processing systems, and use of sample-and-hold modules for vertical interval switching.
Paik/Abe Colorizer - Experimental Television Center Studio System Manual Tools
The Paik/Abe Colorizer is a manual video mixer combining up to seven video signals into the three inputs of a color encoder and routing the output through an amplifier; channel controls include gain pots, on/off switches, color selectors and pan pots. Selector positions include Red, Green, Blue, R-G, R-B and G-B; the unit performs additive mixing, is sensitive to input gain (producing key-like or negative effects), has no built-in voltage control inputs (external video VCAs and voltage-controlled processors can be used). Photographs by Evangelos Dousmanis and Pamela Hawkins document Charlotte Moorman, Shuya Abe (1971), an early Paik/Abe Colorizer and Nam June Paik at Bonino Gallery.
Special Effects Generator - excerpt from the Experimental Television Center Studio System Manual Tools
Excerpt from the Experimental Television Center Studio System Manual describing the Panasonic Special Effects Generator (SEG), a multi-input processor that combines two inputs via mixing, wiping, internal and external keying. The manual documents routing and controls: three main inputs plus an external key at the matrix split to buses A, B and preview; transitions Mix, Wipe, Int and Ext; bar, SUP and Cut functions; inputs 5, 6 and 4 assigned to color bars, black and genlock; outputs to the matrix and patch panel and uses including sending color bars to monitors/VTR, using a color monitor as preview, bypassing the Jones output amp.
