What is the difference between DVI and HDMI?
HDMI is DVI with the addition of: • Audio (up to 8-channels uncompressed) • Smaller Connector • Support for YUV Color Space • CEC (Consumer Electronics Control) • CEA-861B InfoFrames Q. Is HDMI backward compatible with DVI (Digital Visual Interface)? Yes, HDMI is fully backward compatible with DVI compliant devices. HDMI DTVs will display video received from existing DVI-equipped products, and DVI-equipped TVs will display video from HDMI sources. However, some older PCs with DVI are designed only to support computer monitors, not televisions. Consumers buying a PC with DVI should make sure that it specifically includes support for television formats and not just computer monitors. Also, consumers may want to confirm that the DVI interface supports High-bandwidth Digital Content Protection (HDCP), as content that requires HDCP copy protection will require that both the HDMI and DVI devices support HDCP to properly view the video content.
