The HDTV Tri-Sat AutoSwitch Kit allows DIRECTV HDTV subscribers to enjoy high-definition (HD) programming and switch automatically among the DIRECTV 101, 110, and 119 satellites when using a DIRECTV receiver. In addition, since any DIRECTV receiver equipped with a DIRECTV HDTV Satellite Control Module (SCM) can control satellite selection, when multiple SCMs are installed, you can control satellite selection from multiple SCM-equipped receivers.
