Layered mix effects switcher architecture. |
摘要 |
<p>A mix effects based switcher architecture provides for processing of video signals with associated key signals throughout, the mix effects (M/E) (22) banks within the switcher outputting both a composited video signal and a composited key signal for use by subsequent M/E banks. The outputs of the M/E banks may be combined together before being input to an output M/E bank (26). The output M/E bank provides a layered video signal with associated composited key signal at the output of the switcher.</p> |
