Abstract:
1. A vehicle-mounted video communication system comprising: a plurality of image pickup devices, mounted on a vehicle, for transmitting video data obtained by picking up an image, a plurality of video processing devices for processing the video data, a vehicle-mounted video relay device having a connection section connected to said plurality of image pickup devices and the plurality of video processing devices via a plurality of first communication lines respectively, and configured to transmit the video data transmitted from said image pickup devices selectively or in a multiplexed state to the plurality of video processing devices, one first communication line of the first communication lines connecting said vehicle-mounted video relay device to a first video processing device of the plurality of video processing devices, and a branching unit for branching the one first communication line, wherein a remainder of the plurality of video processing devices is connected to the one first communication line branched by said branching unit, the plurality of video processing devices are connected to one another via a second communication line, the plurality of video processing devices include controllers for generating video request data for requesting the video data of a specific one of said image pickup devices respectively, said controller of one of the plurality of video processing devices collects the video request data generated in each video processing device via the second communication line, said one of the plurality of video processing devices includes a transmitting section for transmitting the collected video request data to said vehicle-mounted video device via the one first communication line, and said one of the plurality of video processing devices transmits video request data at intervals of predetermined time, wherein said vehicle-mounted video relay device includes: a receiving section for receiving the video request data transmitted from, said transmitting section, a controller for specifying said image pickup device required to pick up an image, on the basis of the video request data received by said receiving section; and a transmitting section for transmitting video data transmitted from said image pickup device specified by said controller to each video processing device, a timer section for measuring time passed after said receiving section received one item of video request data, and said vehicle-mounted video relay device, when the predetermined time has passed before said receiving section receives another item of video request data, transmits video data transmitted from a predetermined image pickup device to each video processing device.
