what type of port transmits both digital audio and digital video with a single connector

  The HDMI port allows for the transmission of both digital audio and digital video using a single connector.

  HDMI port is a high definition digital connector that transmits both digital audio and digital video at the same time. Its full name is High Definition Multimedia Interface (HDMI) and it is a standardized interface developed by a consortium of electronics manufacturers. HDMI port helps to connect multiple devices together and provides the best possible picture and sound performance.

  The HDMI port uses a small 19-pole connector to transmit the signal. The connector has 19 metal conductors, 5 of which are used to transmit digital signals, 4 for digital audio signals, 8 for digital video signals and 2 for ground. The HDMI port uses the TMDS protocol to carry digital signals. The TMDS protocol is a specific standardized method that allows compatibility between HDMI connectors from different manufacturers.

  In addition, the HDMI port also allows the use of DVI-D or VGA connectors to pass digital signals. DVI-D is a connector with a 24-bit or 30-bit digital channel; while VGA is a connector with a 15-bit or 16-bit digital channel. This means that if you want to display the content on the HDMI port on a VGA display, you must use a VGA connector to transfer the content from the HDMI port to the VGA display.

  In summary, the HDMI port is a standardized, compact and durable connection capable of transmitting digital audio, digital graphics and other related information simultaneously. It not only greatly reduces the number of connections required; it also provides the best graphics and sound representation to meet the ever-increasing demands of video, picture, and sound media streaming.
