Mobile multiplexed slow scan video system
First Claim
1. A mobile vehicle comprising:
- a closed circuit television system;
an electronic data link through which various devices in the vehicle communicate according to a defined data transmission protocol for the vehicle;
the closed circuit television system comprising a television camera for observing a field of view and providing signals representing the field of view;
a television monitor for presenting an image of the field of view; and
a processing system for processing the signals from the television camera into signals for the monitor, the processing system comprising a processor that processes the signals from the television camera to create data signals defining video frames corresponding to fields of view observed from time to time by the video camera and conforming to the defined data transmission protocol for the vehicle and that places the created signals on the electronic data link for transmission to the monitor.

Abstract
A mobile closed circuit television system in which a pre-existing data communication system in a vehicle is used as a medium for transmitting video data from an on-board television camera (12) to an on-board television monitor. The pre-existing data communication system has a data bus (10) that serves various electric and electronic devices throughout a vehicle, and is embodied in wiring modules, or wiring harnesses, that run throughout the vehicle. The pre-existing data bus utilizes an operating protocol embodied in a published standard that is recognized by the industry, SAE Standard J1939, published by the Society of Automotive Engineers, being the particular one utilized in practice of the present invention.
