About HDMI
HDMI (High­Definition Multimedia Interface) is a digital interface standard for
connecting TVs, projectors, Blu­ray Disc/DVD players, set­top boxes, and
other video components. Until now, several separate video and audio cables
have been required to connect AV components. With HDMI, a single cable
can carry control signals, digital video and digital audio (2­channel PCM,
multichannel digital audio, and multichannel PCM).
The HDMI video stream (i.e., video signal) is compatible with DVI (Digital
Visual Interface) (＊1), so TVs and displays with a DVI input can be
connected by using an HDMI­to­DVI adapter cable. (This may not work with
some TVs and displays, resulting in no picture.)
This unit supports HDCP (High­bandwidth Digital Content Protection) (＊2),
so it can display picture only on HDCP­compatible components.

Audio Return Channel, 3D, x.v.Color, Deep Color, LipSync, 4K
