Abstract: Methods, systems, and computer readable media operable for adjusting brightness of a display screen. A first interface is configured to provide information, including display brightness information, to the display device through a high-definition multimedia interface (HDMI). Brightness circuitry is configured to process brightness information from one or more sensors detecting ambient light level. A module is configured to generate control information to control the brightness of the display device and to provide the control information to the display device.

Abstract: Methods, systems, and computer readable media may be operable to facilitate a disabling of a remote control unit for a multimedia device. A multimedia device may be configured with a predetermined input for enabling/disabling an input interface of the multimedia device. An interface lock feature may be enabled at the multimedia device, and when the predetermined input is received at the multimedia device, an input interface of the multimedia device may be enabled or disabled. When the input interface of the multimedia device is disabled, a control device such as a remote control unit may be precluded from operating with the multimedia device.
