Abstract
A method of measuring video latency between a sender and a receiver in a video conference system is disclosed. In an embodiment, the method includes initiating an electrical signal from a first location in a video conference system, transmitting the electrical signal through the video components of the video conference system, reflecting the electrical signal back through the video components of the video conference system and measuring the latency of the electrical signal at the first location related to the transmission and reflection of the electrical signal.
