Interactive TV (Teletext and ISDB-T) Buttons – Required and
Reserved
This section describes the Interactive TV buttons that are supported by Windows Media Center. If
Interactive TV data is supported in the TV signal for the locale that the remote will be distributed
to, Interactive TV buttons must appear on the remote control. These buttons are also used for
Integrated Services Digital Broadcasting (ISDB) Interactive TV functions.
Outside of these two primary video streaming standards, Microsoft reserves these buttons. No
specifications are available for intended Microsoft usage of these buttons. Future use of these
buttons by Microsoft might be incompatible with any implementations generated before the
intended usage is specified.
Additionally, these buttons cannot be overloaded with functionality that works in Windows Media
Center or other programs. These buttons are for Interactive TV functions.
In the Japanese market, the color order for the interactive buttons are (left to right) Blue, Red,
Green, and Yellow.
