When content data is split into multiple pieces of data and there is a request from a client terminal to download the content data, in addition to a transfer to the client terminal from a server that has the content data, the split-up data of the content data is transferred via a P2P communications network from other client terminals that have in a cache region the split-up data of the content data, and the content data is reconstructed within the client terminal, thereby enabling the realization of higher speed data transfer rates by using multiple paths while resolving bottlenecks where traffic is concentrated on the server.

Data transmission and reception system

A display request is received by user input to an input device (step S). With reference to a database, referent data or reference source of data associated with an icon clicked upon the display request is extracted (step S). When more reference source or referent data are present in the extracted data (YES in step S), the process returns to step S. When no reference source or referent data is present in the extracted data (NO in step S), an icon associated with the extracted data is drawn as connected (step S), and the icon is displayed on a display screen (step S).

In a game where a character is moved at a high speed to a goal along a path that is set in a virtual three-dimensional space, an operation mistake is better prevented in a movement operation of the character. A plurality of paths where the character moves are set in parallel in the virtual three-dimensional space. Game control means includes path information storing means for storing a coordinate position and a directional vector that are given to each point of a sequence of points arranged in each of the paths. Additionally, the position coordinate of the character moving in one of the paths is calculated based on the information stored in the path information storing means. A game machine includes a special movement process means for moving, when a special movement input signal is input from a controller pad operated by a player, the character from the path where the character is currently moving to a position coordinate in the virtual three-dimensional space of an adjacent path, by referring to position coordinates of the sequence of points stored in the path information storing means.

A background image acquisition technique is disclosed for acquiring a background image that is required for calculating a background difference in a video game that uses an input image supplied by a camera while enabling command input through image recognition of a player image. The background image acquisition technique involves compositing a button item for responding to an operation of a player with a portion of an image captured by the camera which captured image includes a player image representing the posture of the player, displaying the composite image on a monitor screen, guiding the player into position such that the player image is accommodated within said portion of the captured image, and acquiring an image of a region of the captured image other than said portion as the background image.

A technique is disclosed for detecting a pose of a player in a video game using an input image supplied by a camera. The technique involves calculating a frame difference and/or background difference of an image of a predetermined region of an image captured by the camera which captured image includes a player image representing the pose of the player, and generating operations information corresponding to the pose of the player based on the calculated frame difference and/or background difference.
