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: An apparatus, method and computer-readable medium provide control of set top box volume based on mobile device events. The apparatus may execute a process that includes controlling a volume setting of an audio amplifier to output audio content to the one or more audio or audio/visual devices. A connection event signal from a mobile device is received via a wireless radio frequency receiver. The connection event signal indicates a call state of the mobile device. In response to receiving the connection event signal, a received signal strength indication associated with the connection event signal obtained. A volume setting that corresponds to the obtained received signal strength indication is determined. The volume setting output to the audio amplifier is adjusted according to the determined volume setting.

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.

Abstract: An apparatus and a method for detecting a buffer overflow attack, and a security protection system. The apparatus for detecting a buffer overflow attack includes a memory storing instructions, a processor configured to execute the instructions stored in the memory to obtain external input data for a target process, determine that the target process decodes the external input data, detect attack code on the decoded external input data, wherein the attack code is a code used for performing an overflow attack on a buffer, where the apparatus or the method facilitates detection of attack code from the data obtained by decoding, and may improve a detection rate of the attack code.
