1. A transmission device used in a wireless video transmission system in which a medical image is transmitted and received by radio communication, the transmission device comprising:
a transmission unit capable of performing radio communication with a plurality of receiving devices which are respectively connected to a plurality of display apparatuses and which receive the medical image to be displayed on the display apparatuses; a control unit configured to acquire an identifier for identifying a receiving device connected to a selected single display apparatus when an instruction is received to select one display apparatus on which the medical image is to be displayed from among the display apparatuses, and configured to control the transmission unit such that the identifier will be used when the medical image is transmitted; and a generating unit configured to generate an acquisition request requesting identifiers of the receiving devices connected to the display apparatuses respectively,
whereinthe control unit controls the transmission unit to transmit the acquisition request by using a specified channel set to the receiving devices in common, and controls the transmission unit such that an identifier indicating the receiving device connected to the selected display apparatus from among identifiers included in responses given to the acquisition request will be set to a destination of transmission and the medical image will be transmitted, andin a control process for the transmission unit, the control unit
acquires a first identifier from a firstly received first response from among the responses received from the receiving devices connected to the display apparatuses, and sets the first identifier to a destination of transmission and controls the transmission unit so as to start performing radio communication with a first receiving device connected to a first display apparatus,controls the transmission unit so as to start transmitting the medical image to the first receiving device when an instruction is received to select the first display apparatus, and acquires a second identifier from a second response received after the first response and sets the second identifier to the destination of transmission to control the transmission unit so as to start performing the radio communication with a second receiving device when an instruction is received not to select the first display apparatus, andrepeats, until an instruction to select the receiving device that is performing the radio communication is received, the above processes which comprise:
starting performing radio communication with one receiving device connected to one display apparatus by use of one identifier; andaccording to whether or not an instruction has been received to select the display apparatus to which the receiving device that is performing communication is connected, starting transmitting the medical image or further starting performing radio communication with another receiving device connected to another display apparatus by use of another identifier. |
