The full name of HDMI is High Definition Multimedia Interface, and the Chinese name is the abbreviation of High Definition Multimedia Interface. In April 2002, HDMI was formed by Hitachi, Panasonic, PHILIPS, SONY, THOMSON, TOSHIBA and Silicon Image. HDMI delivers high quality uncompressed hd video and multichannel audio data with a maximum data transfer speed of 10.2Gbps. At the same time, digital/analog or analog/digital conversion is not required before signal transmission to ensure the highest quality of video and audio signal transmission. HDMI1.3 can not only meet the current highest picture quality 1440P resolution, but also support DVD Audio and other most advanced digital Audio formats, support 8-channel 96kHz or stereo 192kHz digital Audio transmission, and only one HDMI cable connection, free of digital Audio wiring. At the same time, the additional space provided by the HDMI standard can be used in future upgraded audio and video formats. Enough to handle a 1080p video and an 8-channel audio signal. Because a 1080p video and an 8-channel audio signal require less than 4GB/s, HDMI has plenty of room. This allows it to connect the DVD player, receiver and PRR separately with a cable. In addition, HDMI supports EDID and DDC2B. Therefore, devices with HDMI have the characteristics of "plug and play". There will be automatic "negotiation" between signal source and display device, and the most suitable video/audio format will be selected automatically.
