    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

No signal (Error Code: DEADBEEF). This could be due to a bad connection or bad weather conditions at your end or 1. Check the cable connections and remove any obstruction around the dish. 2. Try to change channels. 3. Have you tried turning it off and on again?
