Title:
IMAGE DISPLAY DEVICE, FRAME TRANSMISSION INTERVAL CONTROL METHOD, AND IMAGE DISPLAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/199284
Kind Code:
A1
Abstract:
An image display device 1 is communicably connected to a plurality of image transmission devices 21 to 2n over a network 100. A communication device 11 sends a transmission request to each of the image transmission devices 21 to 2n, and receives frames including differential data transmitted by each image transmission device in response to the transmission request. A display unit 141 simultaneously displays images based on the differential data included in the frames received from the image transmission devices. A measurement unit 121 measures, for each image transmission device, a first required length of time, which is the time required from the initiation of transmission of a transmission request to the initiation of reception of a frame, and a second required length of time, which is the time required from the initiation of reception of a frame to the completion of reception. A control unit causes transmission requests to be sent to the image display devices at preset transmission intervals, causes the measurement unit 121 to measure the first and second required lengths of time, and changes the transmission intervals of the transmission requests on the basis of the measurement results.
