  3. Computer Systems Approach to Video Art Tools

    A 1975 proposal to the New York State Council on the Arts and a 1977 report describe a computer-based video synthesis system for synthesizing, processing and controlling video images for artists. The documents list proposed and conventional components including spatial and intensity digitizer, function generator, digital memory, A/D and D/A converters, sync generator with genlock, time-base corrector, chroma keyer, colorizers, keyers and special-effects generators; they define interactive-compositional and automatic-production modes. The system specifies a 1,024-word 16-bit buffer, a DEC LSI-32 microprocessor with Teletype I/O and floppy drives, a 9.7552434 MHz clock phase-locked to a 3.579545 MHz subcarrier, and an X–Y module providing 512 pixels and 18 bits of timing.

  5. Design and Operation of the Spatial and Intensity Digitizer Tools

    The Spatial and Intensity Digitizer (SAID) is an early digital-video prototype developed in 1976 to provide a low-cost video-speed analog-to-digital solution; it used a 6-bit A/D and companion 6-bit D/A to render 64 grey levels. A horizontally locked oscillator slowed the clock to allow variable horizontal sampling that creates adjustable vertical strips and a posterize bit-selection effect. The prototype was available for experimentation at the Experimental Television Center; documented in the 1980 studio manual by Sherry Miller Hocking and Richard Brewster; exhibited at Video History: Making Connections in 1998.

  6. SAID (Spatial and Intensity Digitizer) Tools

    The Spatial and Intensity Digitizer (SAID) was developed for the Experimental Television Center in Binghamton, New York, arising in 1976 from an effort to create a low-cost, video-speed analog-to-digital converter; the project implemented a 6 bit A/D and a companion 6 bit D/A, supported interactive-compositional and automatic-production modes, and produced posterize and mosaic effects in real time. Donald E. McArthur (b.1938; Ph.D. Theoretical Physics, University of Nebraska, 1967) designed SAID and later co-developed the McArthur/Schier Digital Image Generator with Jeff Schier for the Vasulkas; Walter Wright wrote the first program and Ralph Hocking and Jeff Schier participated in hardware arrangements.
