Abstract
A delay time measurement server calculates a video display delay time representing the latency from video transmission to display on a client monitor. The server encodes a specific video, such as a countdown or moving symbol, and transmits it to the monitor. A user provides an input upon observing the specific video, which generates a signal. The server measures the elapsed time between transmitting the video and receiving the generated signal. The server determines the video display delay time based on this elapsed time, accounting for the user's reaction time and network command latency.
