About HDMI
Designed to meet the increased demands of digital TV, HDMI (High Definition Multimedia Interface) is a new digital
interface standard for connecting TVs, projectors, Blu-ray Disc players/DVD players, set-top 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 up to eight channels of digital audio (2-channel 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 HDMI-to-DVI adapter cable. (This may not work with some TVs and displays,
resulting in no picture.)
The AV receiver uses HDCP (High-bandwidth Digital Content Protection)
*2
, so only HDCP-compatible components can
display the picture.
• 2-channel linear PCM (32–192 kHz, 16/20/24 bit)
• Multichannel linear PCM (up to 7.1 ch, 32–192 kHz, 16/20/24 bit)
• Bitstream (DSD, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS, DTS-HD High Resolution Audio, DTS-HD
Master Audio)
Your Blu-ray Disc player/DVD player must also support HDMI output of the above audio formats.
The AV receiver supports HDCP (High-bandwidth Digital Content Protection)

, a copy-protection system for digital
video signals. Other devices connected to the AV receiver via HDMI must also support HDCP.
*1
DVI (Digital Visual Interface): The digital display interface standard set by the DDWG
*3
in 1999.
*2
HDCP (High-bandwidth Digital Content Protection): The video encryption technology developed by Intel for HDMI/DVI. It’s
designed to protect video content and requires a HDCP-compatible device to display the encrypted video.
*3
DDWG (Digital Display Working Group): Lead by Intel, Compaq, Fujitsu, Hewlett Packard, IBM, NEC, and Silicon Image, this
open industry group’s objective is to address the industry’s requirements for a digital connectivity specification for high-
performance PCs and digital displays.
Note
• The HDMI video stream is compatible with DVI (Digital Visual Interface), so TVs and displays with a DVI input can be connected by
using an HDMI-to-DVI adapter cable. (Note that DVI connections only carry video, so you’ll need to make a separate connection for
audio.) However, reliable operation with such an adapter is not guaranteed. In addition, video signals from a PC are not supported.
• The HDMI audio signal (sampling rate, bit length, etc.) may be restricted by the connected source component. If the picture is poor or
there’s no sound from a component connected via HDMI, check its setup. Refer to the connected component’s instruction manual for
details.
The AV receiver’s HDMI interface is based on the following:
Audio Return Channel, 3D, x.v.Color, Deep Color, Lip Sync, DTS-HD Master Audio, DTS-HD High Resolution
Audio, Dolby TrueHD, Dolby Digital Plus, DSD and Multichannel PCM
Supported Audio Formats
