摘要

Problem: The purpose of the present invention is to prevent degradation in picture quality during switching that accompanies encoding of a video signal. Solution: This video switching device is provided with a video switching unit having at least two video signal input units, and an encoder, wherein the video switching device is characterized in that: the video switching unit has a switch control unit and a video switch unit, and the encoder has a control unit and an encoding unit; and, when a camera switchover command signal is inputted, the switch control unit outputs a video signal switchover command signal to the video switch unit after waiting for the top process start signal of an I process to be outputted from the control unit.
