A video switching apparatus comprising: a reception unit which receives video data within a range of a prescribed bandwidth via a network from a plurality of first 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 second apparatus which sends video data; a selection unit which dynamically sets a priority degree of each piece of video data, and selects video data to be received from the plurality of first apparatuses based on the priority degree; and a transmission and reception control unit which controls a transmission and reception of video data, wherein, in a case where 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 wherein the transmission and reception control unit performs a control in a manner that a reception of selected video data is stopped and a reception of the new video data is started and the selection unit selects, up until a total of usage bands of candidates of video data for which reception is to be stopped and a presently empty band becomes a usage band of the new video data or higher, the candidates in an order of the lowest priority degree from among video data being received, and afterwards selects video data to be excluded from the candidates in a range where a total of usage bands of the remaining candidates and a presently empty band does not become a usage band of the new video data or lower, and wherein the transmission and reception control unit performs a control in a manner that a reception of video data finally remaining in the candidates is stopped. a reception unit which receives video data within a range of a prescribed bandwidth via a network from a plurality of first 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 second apparatus which sends video data; a selection unit which dynamically sets a priority degree of each piece of video data, and selects video data to be received from the plurality of first apparatuses based on the priority degree; and a transmission and reception control unit which controls a transmission and reception of video data, wherein, in a case where 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 wherein the transmission and reception control unit performs a control in a manner that a reception of selected video data is stopped and a reception of the new video data is started and the selection unit selects, up until a total of usage bands of candidates of video data for which reception is to be stopped and a presently empty band becomes a usage band of the new video data or higher, the candidates in an order of the lowest priority degree from among video data being received, and afterwards selects video data to be excluded from the candidates in a range where a total of usage bands of the remaining candidates and a presently empty band does not become a usage band of the new video data or lower, and wherein the transmission and reception control unit performs a control in a manner that a reception of video data finally remaining in the candidates is stopped.
