Video chat is a way of communicating online using the Internet where the parties concerned use a camera–microphone combination installed in either their computers or in their smart phones. For streaming video a speed of at least 2 Mbps is needed, to alleviate a choppy signal and disconnects. For sound transmission, much less speed is required, so often during times of heavy network congestion video is often turned off, to maintain connection continuity.
