Patent number: 8079051Abstract: A system includes one or more transmitter devices constructed and adapted to transmit wireless streaming media, the transmitter device connected to at least one video source, wherein the transmitter device is further constructed and adapted to automatically detect a type of active source signal from the at least one video source and automatically to convert that signal, if necessary, to an appropriate output signal; and one or more receiver devices constructed and adapted to receive wireless signals, the receiver connected to at least one video output device, wherein the at least one receiver device is further constructed and adapted to produce, automatically, a appropriate signal for the at least one video output device connected thereto.Type: GrantFiled: August 28, 2009Date of Patent: December 13, 2011Assignee: Avocent Huntsville CorporationInventors: Kevin M. McCafferty, Richard L. Moore, Iain Huntley-Playle, Sheng Li, Richard A. Smith, Rudolph J. Timmerman, C. David Covington
