Both architectures interconnect megapixel image sensors with one central application processor by bridging the long distance over a single coax cable. This requires that the video streams to arrive fully synchronised. While current generation systems are one megapixel (MP) in resolution, but next-generation systems demand image resolutions of two megapixel and more at up to 60 frames per second frame (fps) rate.
Light-emitting diode (LED) flickering caused by the pulse-width modulation (PWM) of LED lights in traffic signs and cars is another problem. In addition, the market demands higher dynamic range (HDR) imaging suitable for extreme lighting conditions, requiring additional pixel processing.
Video stream transmission systems need to feature central clock distribution; video synchronisation, back-channel communication and power over coax (PoC) capabilities. In order to achieve all this, highly integrated solutions feature chipsets of multiple FPD-Link serialises combined with a single FPD-Link deserialiser hub.
This paper from Texas Instruments discusses how to fulfill market demands for HDR, LED flicker mitigation, low-light performance and advanced image quality.
