About HDMI
HDMI is an abbreviation of High-Definition Multimedia Interface, which is
an AV digital interface that can be connected to a TV or amplifier.
With the HDMI connection, high definition video and high quality audio
formats adopted by Blu-ray Disc players (Dolby Digital Plus, Dolby
TrueHD, DTS-HD, DTS-HD Master Audio) can be transmitted, which is not
possible with the analog video transmission.
Furthermore, in the HDMI connection, audio and video signals can be
transmitted through a single HDMI cable, while in conventional
connections it is necessary to provide audio and video cables separately
for connection between devices. This allows you to simplify the wiring
configuration that tends to be quite complex in a home theater system.
This unit supports the following HDMI functions.
