Slow-scan Television - Current Systems

Current Systems

A modern system, having gained ground since the early 1990s, uses a personal computer and special software in place of much of the custom equipment. The sound card of a PC, with special processing software, acts as a modem. The computer screen provides the output. A small digital camera or digital photos provide the input.

Famous quotes containing the words current and/or systems:

    Through this broad street, restless ever,
    Ebbs and flows a human tide,
    Wave on wave a living river;
    Wealth and fashion side by side;
    Toiler, idler, slave and master, in the same quick current glide.
    John Greenleaf Whittier (1807–1892)

    People stress the violence. That’s the smallest part of it. Football is brutal only from a distance. In the middle of it there’s a calm, a tranquility. The players accept pain. There’s a sense of order even at the end of a running play with bodies stewn everywhere. When the systems interlock, there’s a satisfaction to the game that can’t be duplicated. There’s a harmony.
    Don Delillo (b. 1926)
