Abstract A video switcher includes: a reception unit which receives video data within a range of a prescribed bandwidth via a network from video output apparatuses; a transmission unit which selects one or more pieces from among received video data, and transmits the selected one or more pieces to a video processing apparatus; a selection unit which dynamically sets a priority degree of each piece of video data, and selects video data to be received; and a control unit which controls a transmission and reception of video data. When a bandwidth necessary for a reception of new video data is insufficient, the selection unit selects video data for which reception is to be stopped from among video data being received based on the priority degree, and the control unit performs a control so as to stop a reception of selected video data and start a reception of the new video data.
