Abstract
Improved video transition circuitry including circuitry for previewing transitions from an on-air event signal to a next event signal. The circuitry includes a program transition switch responsive to the on-air event and next event signals for outputting the on-air event signal; a preview transition switch respnsive to the on-air event and next event signals for outputting the next event signal; transition control circuitry for either (a) controlling the program transition switch to effect a predetermined transition at the output of the program transition switch from the on-air event signal to the next event signal or (b) controlling the preview transition switch to effect a preview of the predetermined transition at the output of the preview transition switch where the predetermined transition may be, for example, a dissolve, a wipe or a bordered wipe.
