HDMI (High-Definition Multimedia Interface)
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/DVD
player/recorder, 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, or 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 HTX-22HDX uses HDCP (High-bandwidth Digital Content Protection), so only HDCP-
compatible components will display a picture.
Supported Audio Functionality
• Audio Return Channel in HDMI Version 1.4
• 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/DVD player must support HDMI output of these audio formats to use them.
About Copyright Protection
The HTX-22HDX supports HDCP (High-bandwidth Digital Content Protection),
*2
a copy-pro-
tection system for digital video signals. Other devices connected to the HTX-22HDX via HDMI
must also support HDCP.
Use a commercially available HDMI cable (supplied with some components) to connect the
HTX-22HDX’s 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
*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): Led 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 specifica-
tion for high-performance PCs and digital displays.
Audio Return Channel (ARC)
With the Audio Return Channel (ARC), the audio output from an HDMI (1.4) TV can be sent to
the HTX-22HDX via its HDMI OUT, so you can listen to the audio from your TV through the
HTX-22HDX. You’ll need to select the ARC (TV) input on the HTX-22HDX to do this. To use
ARC, your TV must support ARC. If it doesn’t, the ARC setting will be fixed at Off (see
page 44).
