High Definition Multimedia Interface (HDMI) is a fully digital video and sound transmission 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.
HDMI and UDI without the audio transmission function both inherit DVI's core technology "Transmission Minimized Differential Signal" TMDS, which is still essentially an extension of DVI.
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.
