The High-Definition Multimedia Interface (HDMI) is a compact audio/video interface for transmitting uncompressed digital signal/data. It provides alternative digital options to consumer analog cables such as coaxial cable, Radio Frequency (RF), composite video, S-Video, SCART, component video, D-Terminal, VGA and so on. Nowadays, HDMI is widely used on connecting digital audio/video sources such as set-top boxes, digital multimedia players, Blu-ray Disc players, video game consoles, AV receivers and computer display cards etc. to compatible LCDs, Computer Monitors, digital audio devices, and digital televisions.


HDMI supports standard, enhanced or high-definition video format, along with up to 8 channels of digital audio on a single cable to any TV or PC (with 10.2 Gbps of bandwidth). It is independent from various digital television standards such as ATSC and DVB, as these video streams can be decoded and output as uncompressed video stream on HDMI.
HDMI products have started shipping in autumn 2003. Over 800 Consumer Electronics and Computer companies have adopted the HDMI specification/guideline set by the HDMI founders, as HDMI Adopters. DNS Cable is proud to present ourselves as one of the adopters by the HDMI founders.
