What interface is hdml?

hdml's full name is High Definition Multimedia Interface, which means High Definition Multimedia Interface in Chinese. It is a fully digital video and sound sending interface that can send uncompressed audio and video signals.

High Definition Multimedia Interface (HDMI) is a fully digital video and sound sending interface that can send uncompressed audio and video signals. HDMI can be used in set-top boxes, DVD players, personal computers, televisions, game consoles, integrated amplifiers, digital audio and televisions and other equipment. HDMI can send audio and video signals at the same time. Since audio and video signals use the same wire, it greatly simplifies the installation of system lines.

HDMI is designed to replace older analog signal audio and video sending interfaces such as SCART or RCA terminals. It supports various TV and computer video formats, including SDTV and HDTV video images, plus multi-channel digital audio. Both HDMI and UDI without the audio transmission function inherit DVI's core technology "Transmission Minimized Differential Signal" TMDS, which is still essentially an extension of DVI.

HDMI also supports uncompressed 8-channel digital audio transmission (sampling rate 192kHz, data length 24bits/sample), as well as any compressed audio stream such as Dolby Digital or DTS, and also supports the 8-channel used by SACD 1bit DSD signal. In the HDMI 1.3 specification, support for ultra-high data volume uncompressed audio streams such as Dolby TrueHD and DTS-HD has been added.

The initiators of the HDMI organization include major consumer electronics manufacturers, such as Hitachi, Panasonic, Quasar, Philips, Sony, Thomson RCA, Toshiba, and Silicon Image. Digital Content Protection, LLC provides anti-copy protection technology related to HDMI interfaces. In addition, HDMI is also supported by major film production companies such as 20th Century Fox, Warner Bros., Disney, major consumer electronics manufacturers including Samsung Electronics, and many cable TV system operators.
