Some cars already feature systems that can automatically identify road signs or detect when the car is drifting outside of its own lane. These are features that, at least for now, can only be realized using video sensors inside and around the vehicle itself.
Even though the use and importance of video data is increasing in the automotive sector, there are still no globally recognised standards in place to define how the video data should be shared around a vehicle. It is still left up to the manufacturer to choose their preferred solution. This includes proprietary standards such as APIX, GSML and FPD-Link, which support speeds of 6 Gbit/s, 10 Gbit/s and 13 Gbit/s respectively. In addition, the use of automotive-grade Ethernet with speeds of up to 1 Gbit/s is also increasing.
As the demand for bandwidth and resolution increase, the number of video links used in an average vehicle will also build. Standard definition, which only a short while ago was perfectly good for reversing cameras, will be replaced with high definition, high framerate sensors that support high resolution image capture at high traveling speeds.
