USB video class support for Linux is provided by the Linux UVC driver, although as of July 2017 support for still-image capture is not yet implemented. [4] The UVC driver has been included in the Linux kernel source code since kernel version 2.6.26.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
AV synchronization is the coordination of audio and video signals being displayed on a digital TV in proper time. AV synchronization ensures that the audio does not lag behind the video that is being displayed on the TV set or vice versa, so that both audio and video are in sync. [citation needed]

[197] The standard was released in September 2016, and supports all HDMI 1.4b features such as video resolutions up to Ultra HD 30 Hz and CEC. [ 198 ]
Screen time is the amount of time spent using an electronic device with a display screen such as a smartphone, computer, television, video game console, or tablet.

The mechanisms or policies provided by the kernel can be classified according to several criteria, including: static (enforced at compile time) or dynamic (enforced at run time); pre-emptive or post-detection; according to the protection principles they satisfy (e.g., Denning [33] [34]); whether they are hardware supported or language based ...
HDCP devices can create multiple keys, allowing each screen to operate, but the number varies from device to device; e.g., a Dish or Sky satellite receiver can generate 16 keys. [30] The technology sometimes causes handshaking problems where devices cannot establish a connection, especially with older high-definition displays. [31] [32] [33]
A typical modern set-top box, along with its remote control - pictured here a digital terrestrial TV receiver by TEAC. A set-top box (STB), also known as a cable box, receiver, or simply box, and historically television decoder or a converter, [1] is an information appliance device that generally contains a TV tuner input and displays output to a television set, turning the source signal into ...
