HDMI can transmit audio and video signals simultaneously, can transmit uncompressed high-definition video and multi-channel audio data with high quality, and has the highest data transmission speed of 5 Gbps. Without the need for digital-to-analog or analog-to-digital conversion prior to signal transmission. The HDMI specification can be used in conjunction with broadband digital content protection (HDCP) to prevent unauthorized copying of copyrighted video content.
