"BRAVIA™ Sync" is a Sony product feature that allows you to use the remote controls of BRAVIA™ televisions (Sony Corporation products) to operate various devices that are connected to each other through HDMI cables. BRAVIA™ Sync uses the control signals that are transferred through the HDMI connections.
This feature is available starting with CECH-2000 series PS3 systems
To enable the BRAVIA™ Sync feature, go to (Settings) > (System Settings) > [Control for HDMI], and set the option to [On]. For details, refer to the online user’s guide (http://manuals.playstation.net/document/en/ps3/current/settings/ctrlhdmi.html) and the instructions supplied with the BRAVIA™ products in use.
This feature can only be used on devices that support the BRAVIA™ Sync feature. Compatibility with all devices that comply with the HDMI CEC specification is not guaranteed.
