About HDMI
Designed to meet the demands of digital TV, HDMI (High Denition Multimedia Interface) is a new digital interface
standard for connecting TVs, projectors, 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), so only HDCP-compatible components can
display the picture.
Supported Audio Formats
2-channel linear PCM (32192 kHz, 16/20/24 bit)
Multichannel linear PCM (5.1 ch, 3296 kHz, 16/20/24 bit)
Bitstream (Dolby Digital, DTS)
Your DVD player must also support HDMI output of the above audio formats.
About Copyright Protection
The AV receiver supports HDCP (High-bandwidth Digital Content Protection)
*2
, a copy-protection system for digital
video signals. Other devices connected to the AV receiver via HDMI must also support HDCP.
Commercially available HDMI cables (supplied with some components) should be used to connect the AV receivers
HDMI OUT to the HDMI input on your TV or projector.
*1 DVI (Digital Visual Interface): The digital display interface standard set by the DDWG

in 1999.
*2 HDCP (High-bandwidth Digital Content Protection): The video encryption technology developed by Intel for HDMI/DVI. Its 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 groups objective is to address the industry's requirements for a digital connectivity specication for high-performance PCs and
digital displays.
