Windows Media Center Extender
Windows Media Center Extenders (officially "Extender for Windows Media Center" and code named "Bobsled") are devices that are configured to connect over a computer network to a computer that includes Windows Media Center running Microsoft Windows XP Media Center Edition, Windows Vista Home Premium/Ultimate, Windows 7 Home Premium, or Windows 8 with a Pro pack to stream the computer's Windows Media Center software to the Extender device. This allows use of Windows Media Center and its features (such as view photos, videos, listen to music, watch live television and use DVR functions, watch recorded TV, etc.) on a television receiver or other electronic visual display.
The advantage with these devices is that a household's primary computer, hosting Windows Media Center, need not be near the device used for display. Additionally, with an Extender, Windows Media Center can be accessed at the same time by several users. The Xbox and Xbox 360 gaming consoles have Windows Media Center Extender functionality. The Ceton Echo is a stand-alone extender.
