Benefits of technology

[0007]The present invention provides methods, systems, and computer readable media operable to facilitate adjustment of brightness of a display device through an interface or source device, both manually and automatically. Preferably, the display device includes a high-definition multimedia interface and consumer electronics control (HDMI-CEC) functionality, such as a television. Alternatively, the display device may be a mobile device. The interface or source device preferably includes an access point, or a set-top box.
[0008]In one aspect of the invention, an apparatus is provided operable to adjust viewing 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.
[0009]Another aspect of the invention is directed to a method for providing instructions to adjust brightness of a display device connected to a source

Problems solved by technology

Automatic adjustment of TV displays has presented problems.
In darkly lit rooms or very brightly lit rooms, the TV images tend to be either too harsh or washed out with minimal contrast, making it difficult to read text and other critical details.
Unlike a light bulb, a TV is an information display device; more light from the screen is not necessarily better for the user.
Too low a brightness leads to poor illumination in portions of the TV image, while too high a brightness leads to bleaching of fine details within the TV image.
Overly bright displays may incorrectly represent the

Embodiment Construction

[0019]A first interface is configured to be used to receive content including television display brightness information through a high-definition multimedia interface (HDMI) communicating with a consumer electronics control (CEC) enabled television to a set-top box. The set-top box has circuitry to process brightness information from one or more sensors detecting ambient light level and communicating the brightness information to the television through the HDMI. A module is configured to measure the display brightness information based on ambient light level detected by the sensor and execute CEC codes to adjust the display brightness of the television display relative to the measured ambient light level.

[0020]In another aspect of the invention, a set-top box is equipped with Internet connectivity and can communicate with an external device that includes servers for brightness / luminance data collection, customer television channel viewing preferences, viewing times and the like. Sinc
