Abstract

The invention provides a video signal transmitting device, a video signal receiving device, and a video signal transmission and reception system. The video signal transmission and reception system (1)performs transmission of a video signal and a control signal between the video signal transmitting device (10) and the video signal receiving device (20) via a common transmission line (30). The video signal transmitting device (10) includes a video signal transmitter (11), a control signal transmitter and receiver (12), a filter circuit (13), a controller (14), and a camera (15). The video signal receiving device (20) includes a video signal receiver (21), a control signal transmitter and receiver (22), a filter circuit (23), and a controller (24). By performing time management control performed by the controller (14) or the controller (24) such that the period of the transient state of transmission of the video signal is within the non-communication period of the control signal, interference between the video signal and the control signal in the period of the transient state of transmission of the video signal is suppressed.

Description

technical field [0001] The invention relates to a video signal sending device, a video signal receiving device and a video signal transceiving system. Background technique [0002] In recent years, cameras have been installed in various places. For example, cameras are installed at various places on the production line of a factory to monitor the production status, and when any failure occurs in the production line, prompt processing can be taken. In a medical field, for example, a camera is installed at the tip of an endoscope to monitor the inside of a patient, and appropriate treatment can be given to the patient based on the monitoring results. In addition, by installing a plurality of on-board cameras in passenger cars to monitor surrounding traffic conditions, etc., it contributes to the improvement of safe driving. [0003] As can be seen from these examples, the camera needs to be installed at a position where the target object can be photographed. On the other han...
