The PureAV HDMI Interface 3-to-1 video switch allows you to connect to and switch among three high-definition, digital-video source devices through only one High-Definition Multimedia Interface (HDMI) or Digital Visual Interface (DVI) connection on your high-definition television (HDTV).¤¤Its quick adoption has made HDMI one of the most common audio video connections available. It is used on high-definition components, such as HDTVs, up-converting DVD players, HD cable/satellite boxes, entertainment computers, and the newly released Blu-ray and HD-DVD players. This has created a bottleneck at the HDTV connection-with a common scenario featuring three HDMI/DVI sources to only one HDMI/DVI input. The PureAV HDMI Interface 3-to-1 video switch lets you connect three sources into one HDMI input on your HDTV. Then, simply select among the source devices either by pressing the input-selector button on the switch itself, or by using the included remote control to scroll to or directly select a source.¤¤The switch offers an ideal way to connect digital displays such as HDTVs, plasma displays, DLP TVs, LCD TVs, and projectors. HDMI also provides an all-digital connection between such source devices as HDTVs, DVD players/recorders, digital cable/satellite boxes, and AV receivers.
