![]() ![]() HDMI 1.3 adds Deep Color, which allows for significant increases in color depth, including 30, 36, and 48 bits. HDMI versions up to 1.2 as well as DVI offer 24-bit color depth. The latest specification for HDMI, version 1.3, significantly increases video capabilities for future applications beyond HDTV, with support for resolutions to WQXGA (2560x1600) at 60 or 75 Hz. ![]() HDMI versions up to 1.2 support computer graphics rates to at least 1920x1200/60 Hz. Sufficient data bandwidth is available for HDTV up to 1080p, 60 Hz. HDMI supports both computer graphics and HDTV formats. Figure 1: Relative size comparison between the Type A and Type C HDMI connectors. A 29-pin plug, known as Type B and compatible with dual link DVI, is no longer part of the HDMI specification as of version 1.3. HDMI mainly utilizes a 19-pin plug known as Type A, and offers a 19-pin mini-plug called Type C found on camcorders and other portable devices. The notion is that HDMI offers the consumer electronics industry a single interconnect solution which compacts all needed electrical interfaces into one small package consumers consider easy to use. Refer to Table 1 for HDMI 1.3 performance parameters. In 2004, version 1.1 of the specification released, followed by version 1.2 in 2005, and version 1.3 in 2006 with significant performance enhancements. The HDMI consortium, formed in 2002 and released the initial specification that same year. ![]() Consider HDMI as a superset which includes DVI along with multi-channel digital audio support in various formats, copyright protection, and consumer control-all packaged into a connector about half the physical size of the original DVI connector. HDMI encompasses the original DVI electrical interface topology known within the electronics industry as TMDS, or Transition Minimized Differential Signaling. The thrust of this article is to bring into focus the primary advantages, or disadvantages depending on your point of view, of HDMI, the digital High Definition Multimedia Interface. Though designed for consumer applications, HDMI is quickly finding its way into pro AV alongside its predecessor, DVI - Digital Visual Interface. HDMI enables a fully digital AV pathway, avoiding the need for D/A and A/D signal conversion to deliver pristine, high quality computer graphics and HDTV with pixel perfect accuracy. It is prevalent in flat-panel displays and projectors as well as DVD players, Blu-ray Disc players, and even some laptops and PC graphics cards. HDMI, or High Definition Multimedia Interface, is a digital AV interface that supports high resolution computer-video and HDTV as well as multiple channels of audio on a single cable.
