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.
The HTX-22HDX’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 Multi- channel PCM.
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).
