A method automatically limits the transmission of a video stream from a terminal to a network. The method includes a capturing step which captures a video and audio stream from a camera and microphone at a terminal participating in a video-conference. A transmitting step transmits the audio and video streams to the network and a varying step varies the amount of video stream data transmitted in the transmitting step to the network based on an audio level of the audio stream. An apparatus automatically limits the transmission of a video stream from a terminal to a network. The apparatus includes a microphone, a camera, a network interface and a processor. The microphone and camera respectively capture audio and video stream data from a participant in a video conference. The network interface is coupled to a network, for transmitting the audio and video stream data to the network. The processor is coupled to the microphone, the camera and the network interface. In operation, the processor reads the video and audio stream data and varying the amount of video stream data sent to the network interface for transmission to the network based on an audio level of the audio stream. The apparatus is typically a desktop or portable computer or hand-held communications device.
