To allow the delay time of video transmission to be measured while an actual video is taken.SOLUTION: A video transmission delay time measurement system includes a transmitting unit and a receiving unit. The transmitting unit includes a transmitting-side reference signal transmitting section that transmits a transmitting-side reference signal, a blinking marker that blinks a marker light based on the transmitting-side reference signal, a photographing device that takes video including a subject to be photographed and the blinking marker, and a data transmitting section that transmits data of the video. The receiving unit includes a data receiving section that receives the data of the video, a display device that displays the video, a first blinking detection section that detects the blinking of the marker light in the video, a receiving-side reference signal transmitting section that transmits a receiving-side reference signal, and a delay time information output section that outputs information about a video transmission delay time based on a blinking signal indicating the blinking state of the marker light and the receiving-side reference signal.SELECTED DRAWING: Figure 1

    【課題】実際の映像の撮影をしながら、映像伝送の遅延時間を測定することができる。【解決手段】映像伝送遅延時間測定システムは、送信ユニットと受信ユニットと、を備える。送信ユニットは、送信側基準信号を発信する送信側基準信号発信部と、送信側基準信号に基づいてマーカ光を点滅させる点滅マーカと、撮影対象、及び点滅マーカを含む映像を撮影する撮影装置と、映像のデータを送信するデータ送信部と、を備える。受信ユニットは、映像のデータを受信するデータ受信部と、映像を表示する表示装置と、映像における、マーカ光の点滅を検知する第一点滅検知部と、受信側基準信号を発信する受信側基準信号発信部と、マーカ光の点滅状態を示す点滅信号と受信側基準信号とに基づいて、映像伝送遅延時間に関する情報を出力する遅延時間情報出力部と、を備える。【選択図】図1
