APIX: High Speed Automotive Pixel Link

  • Reference work entry

Abstract

With the increasing demand on driver information, multimedia content, and even Internet connectivity, displays and video signaling are receiving increasing attention in the automotive industry. The requirement of transmitting video signals includes applications like infotainment displays, dashboard and head-up displays, and also driver assistance systems that require real-time video streams.

A car environment has specific challenges and requirements that need to be considered for video transport in terms of system design. This chapter provides an overview of common challenges the designer of automotive display and camera applications needs to deal with. On the basis of the architecture of the automotive pixel link (APIX) technology, the article first explains the basic concepts of high-speed video transmissions and then focuses on considerations and mechanisms to overcome issues involved in these.
