Vehicle camera LVDS repeater
First Claim
1. A vision system of a vehicle, said vision system comprising:
- a camera disposed at a vehicle and having a field of view exterior of the vehicle;
wherein said camera captures image data and outputs a low voltage differential signal (LVDS);
an LVDS repeater disposed at the vehicle, wherein said LVDS repeater receives the LVDS signal output by said camera and outputs at least two LVDS outputs to at least two respective and independent receivers, and wherein each of the at least two LVDS outputs is representative of the same LVDS signal output by said camera;
wherein said LVDS repeater comprises a de-serializer to de-serialize the LVDS signal output by said camera;
wherein said LVDS repeater comprises at least two serializers to serialize the at least two LVDS outputs to the at least two respective and independent receivers;
wherein said receivers comprise a receiver of respective ones of at least two devices selected from the group consisting of (i) a vehicle head unit of the vehicle, (ii) a display device of the vehicle, (iii) an electronic control unit of the vehicle and (iv) an image processor for a driver assistance system of the vehicle; and
wherein said LVDS repeater is powered at least in part via power-over-coax (PoC) from at least one of said at least two devices selected from the group consisting of (i) a vehicle head unit of the vehicle, (ii) a display device of the vehicle, (iii) an electronic control unit of the vehicle and (iv) an image processor for a driver assistance system of the vehicle.

Abstract
A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view exterior of the vehicle. The camera captures image data and outputs a low voltage differential signal (LVDS). The system includes an LVDS repeater that receives the LVDS signal output by the camera and outputs at least two LVDS outputs to respective receivers. Each of the at least two LVDS outputs is representative of the LVDS signal output by the camera. The receivers include a receiver of respective ones of at least two devices selected from the group consisting of (i) a vehicle head unit, (ii) a display device, (iii) an electronic control unit of the vehicle and (iv) an image processor for a driver assistance function.
