It is an abbreviation for High Definition Media Interface. HDMI is an interface developed in 2003 for digitally transferring audio (audio) and video (video) data without compression.

HDMI connects devices such as blu-ray disc player, HD-DVD disc player, computer, game console, digital satellite receiver to compatible audio and video devices (e.g. "HD Ready" LCD television). It started to appear in HDTV, camcorders and digital cameras in 2006 as well.

Along with DRM (Digital Rights Management) technology, which aims to secure copyrights and provides access control, as an alternative to analog video interface standards such as RF (coaxial cable), composite video, component video, S-Video, SCART, VGA and digital interface standards such as DVI. brings. It is backward compatible with DVI and also carries audio. With version 1.4, it also makes ethernet communication.


HDMI supports the transmission of standard, enhanced and high definition video and multi-channel audio signals over a single cable. It is independent of digital TV standards that define the stream of MPEG compressed video data such as DVB (-T,-S,-C) and ATSC. Such data is routed to the HDMI output as fully decoded (uncompressed video) by a decoder.

Devices are manufactured according to different versions (eg 1.0 or 1.3). Although all versions use the same cables, their data transfer capabilities differ. For example, the first version has 1080p 60 fps support, while the 1.4 version supports 4K × 2K (4096*2160) with 340 MHz bandwidth.

HDMI also supports 8-channel, 192KHz, 24-bit uncompressed audio, as well as Dolby Digital and DTS support. With version 1.3, lossless compression methods such as Dolby TrueHD and DTS-HD Master Audio began to be supported.

Compatible with DVI interface carrying HDMI digital video (DVI-D or DVI-I). This interface (DVI) is used in many computers and video cards. In other words, a device with DVI-D output can be connected to a monitor with HDMI input with the appropriate adapter or cable. However, audio connection or remote control functions will not be possible.
