What are the advantages of HDMI?
Quality: Because HDMI technology is a digital interface, it provides the best quality of the video since there are no lossy analog to digital conversions as they are required for all analog connections (such as component or S-video). The difference is especially noticeable at higher resolutions such as 1080p. Digital video will be sharper than component, and eliminates the softness and ghosting found with component. Small, high contrast details such as text bring this difference out the most.
HDMI can use for both video and audio,which make it convenient,eliminating the cost.And it is a two-way connection, it enables new levels of system intelligence.The connected devices can read each others EDID data auto-configure for optimal performance,and even control each others’ actions via the CEC channel,enabling”one-touch”command of multiple components in a system.
Intelligence: The HDMI interface supports two-way communication between the video source (such as a DVD player) and the DTV, enabling new functionality such as automatic configuration and one-touch play. By using HDMI connectivity, devices automatically deliver the most effective format (e.g 480p vs 720p, 16:9 vs 4:3) for the display that it is connected to – eliminating the need for the consumer to scroll through all the format options to guess what looks best.
HD Content-Ready: HDMI devices supporting HDCP have the comfort of knowing they will have access to premium HD content now and in the future. HD-DVD and Blu-ray have delayed the activation of the image constraint token (a.k.a. content protection flag) with today’s HD movies to help minimize potential issues caused by the transition, but are expected to activate this in a few years, meaning future HD movies will then not be viewable at HD resolutions over unprotected interfaces such as analog component.
When you install HDMI, you can be confident that it will serve the client’s needs for many years to come. Unlike those old analog wires, it’s built for the future of CE technology, not the past.
