HDMI (High Definition Multimedia Interface) is the acknowledged connection standard used for transferring video and audio digitally from a source to a video display device or other compatible home entertainment devices.
HDMI also includes provisions for:
HDMI-CEC (Consumer Electronics Control); This allows remote control of multiple connected HDMI devices from one remote. An example would be using a TV remote to control some functions of Blu-ray Disc player, home theater receiver, or soundbar connected to the TV via HDMI. HDCP (High-bandwidth Digital Copy Protection), This allows content providers to prevent their content from being illegally copied through devices connected using HDMI connections.
