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)

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)

, so only HDCP-compatible 

components can display the picture.

The AV receiver’s HDMI interface is based on the 
following:
Audio Return Channel, 3D, x.v.Color, DeepColor, Lip 
Sync, 4K Passthrough, DTS-HD Master Audio, DTS-
HD High Resolution Audio, Dolby TrueHD, Dolby 
Digital Plus, DSD and Multichannel PCM.

• 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.

DVI (Digital Visual Interface): The digital display interface 
standard set by the DDWG

*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. 

• 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.
