23. A host processor to camera interface, comprising:
-
a camera side interface, including;
a camera side link layer coupled to a camera, the camera providing video data, the camera side link layer converting the video data to a desired video data format;
a serializer coupled to the camera side link layer for serializing the video data in the desired video data format; and
a camera side transmitter coupled to the serializer, the camera side transmitter transmitting the serialized video data;
a host processor side interface, including;
a host processor side receiver for receiving the serialized video data;
a deserializer coupled to the host processor side receiver, the deserializer deserializing the serialized video data; and
a host processor side link layer coupled to the deserializer and a host processor, wherein the host processor side link layer is adapted to convert the deserialized video data into a format compatible with the host processor when required; and
a cable for carrying the video data, the cable including a pair of power wires for carrying power, the cable coupling the camera side transmitter to the host processor side receiver. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A host processor to camera interface for a motor vehicle, comprising:
-
a camera side interface, including;
a camera side link layer coupled to a camera, the camera providing video data, the camera side link layer converting the video data to a desired video data format, wherein the camera is attached to the motor vehicle;
a serializer coupled to the camera side link layer for serializing the video data in the desired video data format; and
a camera side transmitter coupled to the serializer, the camera side transmitter transmitting the serialized video data;
a host processor side interface, including;
a host processor side receiver for receiving the serialized video data;
a deserializer coupled to the host processor side receiver, the deserializer deserializing the serialized video data; and
a host processor side link layer coupled to the deserializer and a host processor, wherein the host processor side link layer is adapted to convert the deserialized video data into a format compatible with the host processor when required, and wherein the host processor is incorporated within an electronic control unit (ECU) of the motor vehicle that is remote from the camera; and
a cable for carrying the video data, the cable including a pair of power wires for carrying power, the cable coupling the camera side transmitter to the host processor side receiver, wherein the camera side link layer is configured to convert a plurality of camera video data formats into the desired video data format, and wherein the camera video data formats include a single 8-bit data format, a dual 8-bit data format, a single 16-bit data format, a single 24-bit data format and a single 12-bit data format. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42)

43. A method for sharing a pair of signal wires, comprising the steps of:
-
providing a trigger pulse from a host processor side link layer to a camera side link layer through a power line;
disabling a serializer in the camera side link layer and enabling a serial-to-camera (SERTC) channel receiver in the camera side link layer in response to receiving the trigger pulse on the power line;
monitoring the status of the pair of signal lines by examining outputs of a deserializer located in the host processor side link layer;
enabling a SERTC channel transmitter located in the host processor side link layer to establish a serial communication interface (SCI) between a camera coupled to the camera side link layer and a host processor coupled to the host processor side link layer via the pair of signal lines when the outputs of the deserializer indicate the pair of signal lines are free. - View Dependent Claims (44)
