Abstract: An information processing apparatus includes a detection unit, an acceptance unit, and an image control unit. The detection unit is capable of detecting whether or not each of a plurality of reproduction apparatuses constitutes a group related to reproduction of content, each of the plurality of reproduction apparatuses being connected to a network, each of the plurality of reproduction apparatuses being capable of reproducing the content. The acceptance unit accepts a user operation related to constitution of the group. The image control unit outputs a group state image based on a detection result by the detection unit, the group state image representing a constitution state of the group, the group state image including an image of each of the plurality of reproduction apparatuses, and controls the group state image in response to the accepted user operation related to constitution of the group.

Abstract: Provided is a video image converter that generates attitude data of a projector based on motion data in projecting moving picture data, stores the attitude data in a storage unit, corrects the moving picture data based on the attitude data, and stores the corrected moving picture data in the storage unit. The projector plays back the corrected moving picture data stored in the storage unit and projects the corrected moving picture data onto a projection plane. A cradle supports the projector and changes an attitude of the projector based on the attitude data stored in the storage unit.

Abstract: To perform highly functional projection with an intuitive operation using a portable terminal. A projection system includes: a portable terminal; a projection device; and a cradle. The portable terminal detects a change in posture of the portable terminal itself. The projection device reproduces a video signal, and projects video thus reproduced on a projection surface. The cradle supports the projection device. The cradle changes the posture of the projection device in accordance with a detection result of the portable terminal.

Abstract: [Object] To suppress the load in playing back a moving picture in a projector having no advanced picture processing function. [Solution] A video image converter generates attitude data of a projector on a basis of motion data in projecting moving picture data, store the attitude data in a storage unit, correct the moving picture data in accordance with the attitude data, and store the corrected moving picture data in the storage unit. The projector plays back the corrected moving picture data stored in the storage unit and project the corrected moving picture data onto a projection plane. A cradle supports the projector and change an attitude of the projector in accordance with the attitude data stored in the storage unit.
