Abstract: Disclosed are an apparatus and a method for transmitting data so as to maximally recover lost data packets by a forward error correction (FEC) scheme in a wireless communication based internet protocol (IP) network. The apparatus for transmitting data confirms a state of data samples according to data patterns of data patterns to be transmitted through a wireless channel, calculates state probabilities of the data samples according to the state of the data samples, determines the generation of redundant data packets of the data packets based on the state probabilities of the data samples, generates the redundant data packets using the data packets according to the determination of the generation of the redundant data packets, and transmits the data packets and the redundant data packets through the wireless channel.

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.
