A wireless video transmission device, comprising: a first wireless communication unit for communicating with a first access point; a second wireless communication unit for communicating with a second access point serving as a candidate for a handover destination from the first access point; and a communication control unit for controlling wireless communication operations of the first and second wireless communication units (15,16); wherein the communication control unit determines whether and how a transmission is to be made for each of the first and second wireless communication units (15,16) according to a quality of communication with the first access point and a status of handover to the second access point, and controls the transmission of encoded high priority video data and encoded low priority video data, the high priority video data and the low priority video data having at least mutually different image regions or mutually different image resolutions in relation to video data corresponding to a captured image, from each of the first and second wireless communication units (15,16) as two individual video streams, wherein the communication control unit causes both of the video streams to be transmitted from the first wireless communication unit to the first access point when the quality of communication with said first access point does not meet a first reference criterion, wherein the communication control unit causes one of the two video streams to be transmitted from the second wireless communication unit to the second access point when the quality of communication with said first access point does not meet a second reference criterion, said second reference being poorer than the first reference. a first wireless communication unit for communicating with a first access point; a second wireless communication unit for communicating with a second access point serving as a candidate for a handover destination from the first access point; and a communication control unit for controlling wireless communication operations of the first and second wireless communication units (15,16); wherein the communication control unit determines whether and how a transmission is to be made for each of the first and second wireless communication units (15,16) according to a quality of communication with the first access point and a status of handover to the second access point, and controls the transmission of encoded high priority video data and encoded low priority video data, the high priority video data and the low priority video data having at least mutually different image regions or mutually different image resolutions in relation to video data corresponding to a captured image, from each of the first and second wireless communication units (15,16) as two individual video streams, wherein the communication control unit causes both of the video streams to be transmitted from the first wireless communication unit to the first access point when the quality of communication with said first access point does not meet a first reference criterion, wherein the communication control unit causes one of the two video streams to be transmitted from the second wireless communication unit to the second access point when the quality of communication with said first access point does not meet a second reference criterion, said second reference being poorer than the first reference.
