実時間映像伝送システムの総合遅延時間の一計測法

抄録

This paper presents a method which measures the transmission delay time of real-time scene from the video camera onto the distant screen. The camera takes a picture of a timer with on-off marker and sends it to the screen. Another timer ticking away the same time is placed nearby that screen. When the image of on-off marker has been drawn on the screen, this timer catches its light and shows that time. Then, we can read the difference of the two timers as the total delay. A trial equipment succeeds to measure it along the real-time HD-TV displayed on Organic EL and also H.264 on LCD with a resolution of 0.1ms. The experimental values agree with the analytical characteristics.
