    摘要： A communication promotion method is provided to appropriately support communication by a plurality of users in different environments. A character 2, operable by an IRC client 5, is linked to or installed in a user terminal 8. An administration device 3 detects a specific event in a channel and sends a specific command to the IRC client 5 via IRC. Commands do not always have to be sent to all of the IRC client 5, and may be different according to the IRC client 5. The user terminal 8 detects the aforesaid command and sends it to the character 2. Characters at each user terminal 8 operate as specified by the command.

    摘要： An update region extraction unit extracts a region that is updated as a moving image as a moving image update region from a screen stored in an image memory that holds a screen on which an image of execution results of a computer is drawn. A division state determination unit determines a division state of the moving image update region from information including a network bandwidth, a threshold value of the transmission time set in advance, an average compression ratio of a frame encoded without using the inter-frame prediction, and an average compression ratio of a frame encoded by using the inter-frame prediction. An update region division unit divides the update region that has been determined to be the moving image region in the determined division state. And an update region transmission unit transmits the divided update region to the terminal device.

    摘要： An information processing apparatus that generates images for displaying a computer execution result on a display unit of a terminal device connected through a network and that transmits the images to the terminal device. The apparatus includes an image memory that holds the images; a first transmitting unit that transmits the images, a detecting unit that detects an area obtained by updating accumulated changes between frames of the images or a frequency of changes between frames of the images, and a second transmitting unit that compresses the images by a compression method and that transmits the compressed images, when the area or the frequency detected by the detecting unit is larger than or equal to a predetermined threshold, the compression method being different from a compression method for the first transmitting unit.
