The distributed controller sends a packet transmission request to the second distributed client, and the distributed media processor receives a packet from the second distributed client and sends the received packet to the first distributed client based on the switching entry.

Abstract: Disclosed herein are an apparatus and method for changing a main screen based on distributed telepresence. A distributed telepresence-based control server includes a main speaker change request reception unit for receiving a main speaker change request for requesting change of a main speaker from a first speaker who is an existing main speaker to a second speaker different from the first speaker. A video transmission requesting unit requests a client of the second speaker to transmit a high-resolution video of the second speaker in response to the main speaker change request. A video transmission stop request reception unit receives a video transmission stop request for requesting stop of transmission of a high-resolution video of the first speaker. A video transmission stop requesting unit requests a client of the first speaker to stop transmitting the high-resolution video of the first speaker in response to the video transmission stop request.
