HDMI advantages compared to existing analog video interfaces such as composite, S-Video and component video:
　　1, Quality: HDMI is a digital interface, since all analog connections (such as component video or S-video) requires no losses when converted from analog to digital, so it provides the best video quality. This difference in higher resolution, for example, is particularly evident when 1080p. 　　Digital Video sharper than component video, eliminating the softness and smearing component video found. Such small, such as text, high-contrast detail will this difference to the limit.
　　2. Ease of use: HDMI integrate video and multi-channel audio in a single cable, eliminating the cost of the current A / V systems use multiple cables, complexity and confusion. This is especially useful when upgrading or adding equipment.
　　3, high intelligence: HDMI supports video source (such as a DVD player) and two-way communication between the DTV, enabling new functionality such as automatic configuration and one-touch play. By using HDMI, devices automatically transmitted to the monitor connected to the most efficient format? (Eg 480p vs 720p, 16: 9 vs 4: 3) eliminates the need to scroll all the formatting options for consumers to guess the best viewing format trouble.
　　4, high-definition content Ready: HDMI devices HDCP support can access the advanced high-definition content, we bring some comfort to me. HD-DVD and Blu-ray has to today's high-definition movie images boycott delayed start tag (also known as content protection flag) to help minimize the potential problems due to the result of the conversion, but is expected to start this mark in a few years , it means that the future of high-definition movies will not be able unprotected interfaces (such as analog components) to high-definition playback. Shopping tips:
　　First, confirm the version of the HDMI cable to note that the version of the HDMI cable
　　Common are three versions 1.3 and 1.4,2.0. Proposed purchase version 2.0 HDMI cable, bandwidth up to 21.8Gbps, support 3D transmission to meet the higher resolution, refresh rate and color depth, can support more than 1080P HD playback, and 1.3, 1.4 and functionally compatible.
　　Second, pay attention to the size of the HDMI interface
　　HDMI interface standard port, mini mouth of the points. Because of size constraints, HDMI interface on the high-definition MP4 basically mini port, so for high-definition MP4 selected HDMI cable, you must look for standard - mini "HDMI cable, otherwise not get.
　　Three, HDMI lines are not as long as possible
　　A single HDMI cable theoretical transmission distance is 7-8 meters, but the actual use, do not need that long. Before buying, the best measure the desired length, as long as the measurement results of 50 cm margin is enough.
　　Fourth, select the brand HDMI cables, more peace of mind
　　If you think your eyesight is difficult to judge which one is better HDMI cable, the easiest way is to choose the brand HDMI cables, such as eda, YARBO, Fujicables, monsters and other brands. The quality is quite guaranteed!
