Construction of a Raster Manipulation Unit - Revision by Jason Bernagozzi at Signal Culture, 2016 Tools

Construction of a Raster Manipulation Unit — Revision by Jason Bernagozzi (2016) is a revised documentation developed in part from the Experimental Television Center's original 1980 document by Sherry Miller Hocking, Walter Wright, Richard Brewster and Dave Jones; the original aimed to preserve methods of building the tool as conceived by Nam June Paik and Shuya Abe and the concepts behind its operation and functions. Bernagozzi's revision is based on that original and is supplemented by new research by Bernagozzi, Signal Culture and Dave Jones; the new documentation is presented not as a replacement but as a reinvestigation using modern concepts and methods.

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.
