Abstract: [Object] To provide a communication control device configured to efficiently secure bands of an IP network in order to transmit data streams. [Solution] There is provided a communication control device including: a channel information acquisition unit configured to acquire, when AV streams are transmitted from a plurality of transmission apparatuses to one or more reception apparatuses on an IP network while being switched, all channel information from the transmission apparatuses to the reception apparatuses; a traffic calculation unit configured to calculate a maximum traffic generated in switching patterns of the transmission of the AV streams from the transmission apparatuses to the reception apparatuses, on the basis of the channel information acquired by the channel information acquisition unit; and a transmission band reservation unit configured to reserve a transmission band on the IP network, on the basis of the maximum traffic calculated by the traffic calculation unit.

Abstract: PROBLEM TO BE SOLVED: To suppress quality degradation of a right-eye image and a left-eye image caused by network transmission.SOLUTION: An information processing apparatus comprises an encoder. The encoder extracts a reference block from one of the right-eye image and the left-eye image, extracts from the other parallax reference block corresponding to the reference block, and generates parallax information representing the distance from the display position of the parallax reference block to that of the reference block. Then, the encoder extracts a motion reference block corresponding to the reference block from one of the images of the previous frame, generates motion information representing the distance from the display position of the motion reference block to that of the reference block, and generates error correction code information to be given to the reference block, on the basis of the parallax information and the motion information.
