An information processing device includes a video processing unit that generates a synthesized video by synthesizing an object video and a second video obtained by rendering second 3D background data, the object video being cut out from a captured video obtained by imaging an object with a display device as a background, the display device displaying a first video obtained by rendering first 3D background data.

Information processing device, video processing method, and program

A method of information processing in a server/client system including a server for storing content and a client for receiving from the server and storing copy content of the content stored in the server. The method includes the steps of: the server generating at least either a content-ID list storing content-IDs corresponding to content for which use-expiration-date updating is permitted out of the copy content stored in the client or a content-ID list storing content-IDs corresponding to content for which use-expiration-date updating is not permitted, transmitting the content-ID list to the client; and the client selectively performing update processing of use-expiration date out of the copy content stored in that client or invalidation processing of the copy content stored in that client based on the content-ID list received from the server.

Server/client system for managing the transmission and use of copyrighted content, information processing unit, information processing method, and computer program

An information-processing apparatus, functioning as a content-utilization management server, includes a storage unit for storing a list of member clients, which are each a client having a right to utilize a content, and a data-processing unit for carrying out a process to register a client on the list of member clients to serve as a member client. The data-processing unit carries out a process to register a client on the member-client list to serve as a member client on condition that results of confirmation indicate that a client making a request for registration of the client to serve as a member client is a client in the same local network as the content-utilization management server and indicate that a user of the content-utilization management server has given an approval of the requested registration of the client to serve as a member client.

A method of growing a single crystal of KTiOPO.sub.4 which is a nonlinear optical material is disclosed. Growth of the single crystal of KTiOPO.sub.4 is carried out by melting a KTiOPO.sub.4 material with a flux to produce a melt, then contacting a seed crystal to the melt, and by slowly cooling at a saturation temperature or below. At this time, molar fractions of K.sub.2 O, P.sub.2 O.sub.5 and TiO.sub.2 contained in the melt fall within a region surrounded by six point in a K.sub.2 O-P.sub.2 O.sub.5 -TiO.sub.2 ternary phase diagram of A (K.sub.2 O:0.4150, P.sub.2 O.sub.5 :0.3906, TiO.sub.2 : 0.1944), B (K.sub.2 O:0.3750, P.sub.2 O.sub.5 : 0.3565, TiO.sub.2 : 0.2685), C (K.sub.2 O: 0.3750, P.sub.2 O.sub.5 : 0.3438, TiO.sub.2 : 0.2813), D (K.sub.2 O: 0.3850, P.sub.2 O.sub.5 : 0.3260, TiO.sub.2 : 0.2890), E (K.sub.2 O: 0.4000, P.sub.2 O.sub.5 : 0.3344, TiO.sub.2 : 0.2656), and F (K.sub.2 O: 0.4158, P.sub.2 O.sub.5 : 0.3744, TiO.sub.2 : 0.2098). In addition, K.sub.15 P.sub.13 O.sub.40 or the same composition produced by melting is used as the flux, and the proportion of a KTiOPO.sub.4 element in a composition of the melt is prescribed to 83.5 to 90.0 mol %. The seed crystal is set so that a C axis is in a direction perpendicular to a melt surface. Then, the seed crystal contacted to the melt is rotated and slowly cooled. Thus, a single crystal of KTiOPO.sub.4 of single domain at the end of growth can be produced.
