Abstract
There is provided a transmission system transmitting at least one of image data and audio data among a plurality of transmission terminals. A first transmission terminal includes a state detector that detects whether a user is present therearound, and a controller that controls to transmit correspondence data corresponding to a result detected by the state detector to a second transmission terminal when a state detected by the state detector changes. The second transmission terminal changes quality of at least one of the image data and the audio data that is transmitted to the first transmission terminal in accordance with the correspondence data and transmits at least one of the image data and the audio data when the second transmission terminal receives the correspondence data.
