 HDMI features high transmission rate, wide transmission bandwidth, high compatibility, and can transmit uncompressed audio and video signals. Compared with the traditional full analog interface, HDMI simplifies connection between devices and provides HDMI-specific intelligent features, which are ideal for high-quality audio and video transmission of small-sized devices.
