The number of vehicles incorporating automotive video systems has been increasing steadily and it’s only logical for car manufacturers to want to incorporate HDMI connectivity into vehicles. HDMI 1.4 provides the solution to these demands with the automotive connection system which was designed specifically to cater to the demands of watching HD video on a dashboard display or seatbacks while driving.

What is the Automotive Connection System?

To understand the automotive connection system, you need to know its key elements which are:

  • A special Automotive HDMI cable that was specifically designed for the distribution and transmission of HD data or signals in automobile embedded systems. The components of this specification include the cables, the relays and the latching connectors and these are all involved in the internal transmission and distribution of HD video in an automobile. The automotive connection system is specially designed to withstand the automobile harsh environment which is subject to vibration, heat and noise disturbances.
  • A standard automotive HDMI cable that was specifically designed to support the connection of digital still cameras, portable media players, phones, camcorders, Blu-ray players and other external devices to HDMI-enhanced systems in a vehicle. This connector is also referred to as the Type E connector.

This means that if you own an HDMI-equipped vehicle, you can play high definition videos from your portable external digital devices while driving.

What is the Difference between the Standard Automotive Cable and Other Standard HDMI Cables?

Standard HDMI cables can only be used with HDMI-equipped devices in the home. Due to the unique stress factors associated with the transmission and distribution of HDMI content in an automobile, Standard HDMI cables will not suffice for connection. On the other hand, the Standard automotive cable has been designed with special components to handle the demands of a HDMI connection system in an automobile. The standard automotive cable supports clear and strong signal transmission especially, that necessary for automotive video systems.

In essence, connecting your external digital devices to your vehicle’s HDMI video system, you’ll need the automotive HDMI cable with micro, mini or standard connectors determined by the application in use.

Limitations of the Automotive Connection System

At the moment, the video resolution supported by an in-vehicle automotive connection system is limited to 1080i and 720p and the cable is yet to support Ethernet.

Enjoying Automotive Connection System

In order to ensure that you can access the features of the automotive connection system in your car, you need to take note of the following points:

  • Ensure that your vehicle is enabled to support HDMI video systems. Also, the content sources such as digital still cameras, camcorders, portable media players and Blu-ray disc players must be HDMI-enabled.
  • Use the correct cable. Since signal transmission and distribution in an automobile is subjected to more stress than that experience in home entertainment devices, you need the standard automotive HDMI cable.
