This software is installed locally, on each P15x.  It can be configured individually, or from a central computer.  We can even load your educational videos onto the systems' hard drive for on-demand playback at any time.  It has a password-protected Administration page (accessed by on on-screen key code) to configure the systems whitelist/blacklist, the startup TV channel, and a list of Favorites for use by the patient.  This computer is set up so that a patient has no chance of altering the systems' configuration, or getting any viruses loaded onto the system.  When the TV is powered back on, the embedded Windows XP software returns to a clean state, ready for the next patient.
