SYSTEM AND METHOD FOR TRANSMITTING CAMERA-BASED PARAMETERS WITHOUT A DEDICATED BACK CHANNEL

摘要

A vehicle system and method for transmitting camera-based parameters and video data includes a video camera disposed on a vehicle for viewing an exterior region. The video camera includes an image sensor for generating a video data stream from an exterior region of the vehicle, a controller for providing camera-based parameters, and an image signal processor. The image signal processor is configured to receive the video stream from the image sensor, receive camera-based parameters from the controller, transfer the camera-based parameters onto the video stream, and output an analog signal that includes the video stream and the camera-based parameters. An electronic control unit receives the analog signal, retrieves the camera-based parameters from the analog signal. A vehicle display receives and displays the video stream.

1. A method for transmitting camera-based parameters and a video stream from a video camera disposed for viewing a region of a vehicle to an electronic control unit mounted on the vehicle, comprising:
generating a video stream with an image sensor mounted on the vehicle; transferring camera-based parameters onto the video stream and providing an analog signal carrying the video stream and the camera-based parameters; transmitting the analog signal to the electronic control unit; and retrieving the camera-based parameters from the analog signal.
