Showing Video from all Sources
Once video has been fully integrated into a curriculum, it starts to come from many different sources, including a class of laptops, DVD players, cable TV and others. To quickly and efficiently put it all on-screen requires video switchers, like Extron’s SW8 VGA Ars and SW12 VGA Ars switchers, which have 8 or 12 inputs. The devices can not only sense what type of input is being used but they good for old-fashioned analog video as well as high-resolution video streams. The switchers also smooth out audio signals so everyone in the class can hear the show as well as see it.
