Abstract: The present invention relates to a program and an information processing method and apparatus with which a connection can be formed reliably between apparatuses having different capabilities. A first application, using a presence function, announces a profile space ID representing processing for a service that can be provided. A second application receives the announcement. The second application requests the first application for detailed information of the service and registration to the service. The second application connects to the first application by peer to peer, based on a URI needed for peer-to-peer access, transmitted from the first application. The present invention can be applied to personal computers, network-enabled CE devices, and commercial application servers on the Internet.

Abstract: A display control apparatus for controlling display in a first display device that displays a predetermined display range of an entire supplied image is provided. The display control apparatus includes an image scaledown unit adapted to scale down a first image based on a scaledown ratio that is preset in accordance with the size of the display range relative to the entire image; and a display control unit adapted to control display of the first image that is scaled down by the image scaledown unit in the first display device.

Abstract: The present invention relates to a program and an information processing method and apparatus with which a connection can be formed reliably between apparatuses having different capabilities. An application #1, using a presence function, announces a profile space ID representing processing for a service that can be provided. An application #n receives the announcement. The application #n requests the application #1 for detailed information of the service and registration to the service. The application #n connects to the application #1 by peer to peer, based on a URI needed for peer-to-peer access, transmitted from the application #1. The present invention can be applied to personal computers, network-enabled CE devices, and commercial application servers on the Internet.

Abstract: The present invention relates to a program, an information processing method and apparatus, and a data structure with which connection can be formed reliably between apparatuses having different capabilities. A service that can be provided to another party is represented by five dimensional parameters, namely, Access Method, Link Speed, X scale, Y scale, and Audio Codec. The values of the parameters are all represented by integer values. Access Method is represented by number 1 in the case of RTSP/TCP+RTP/UDP, and by number 2 in the case of HTTP tunnelling. Link Speed is normalized by kbps as a base unit, and X scale and Y scale are normalized by 16 pixels as a base unit. Audio Codec supports predetermined methods represented by numbers 0 to 6. The present invention can be applied to a personal computer.

Abstract: The present invention relates to an information processing apparatus and method, and to a program that ensure connection between devices connected to transmission paths of various transmission speeds. A media IM client #1 logs in to a media IM server 14 and executes a speed measurement process with a measurement server 200 to determine its uplink speed and downlink speed. A media IM client #2 at the other communication party also logs in to the media IM server 14 and executes a speed measurement process with the measurement server 200 to determine its uplink speed and downlink speed. The media IM clients #1 and #2 exchange the determined speeds via the media IM server 14, setting a set speed, and communicate with each other at the set speed. The present invention is applicable to a personal computer, a network-enabled CE device, and a commercial application server on the Internet.

Abstract: There is provided an information sharing processing method comprising the steps of a page display processing step for acquiring a file from a predetermined server on a network and displaying the file as a page, wherein the file is described in a predetermined page description language and includes a description of link information to another file on the network; a common-screen display processing step for displaying an icon representing a user at a position on a common screen shared with the user and displaying a message issued by the user making an access to the same page as the page displayed at the page display processing step, wherein information on the position and the message are specified by the user in shared data transmitted by the user by way of a shared server on the network; and a screen superposition processing step for superposing the common screen displayed at the common-screen display processing step on the page displayed at the page display processing step.

Abstract: A connection is reliably made between devices having either unidirectional or bidirectional moving-image streaming function, so that information can be transferred. Each terminal notifies a connection server about which one of a bidirectional function and a unidirectional function the terminal has. The connection server notifies the functions of each terminal to the other terminals. The terminal having a unidirectional function transmits a URI for transmitting data to a terminal having a bidirectional function, with which communication is performed, but the terminal having the bidirectional function, which communicates with the terminal having a unidirectional function, does not transmit a URI used to transmit data to the terminal having a unidirectional function. The present invention can be applied to a personal computer which transfers communication data in the Internet.

Abstract: A handwriting input apparatus allows erasure of a displayed figure by a simple handwritten input. When all of a sequence of handwriting points H (indicated by black dots in the figure) composing a locus of a single stroke of handwritten input is located within a proximity area (shown by broken lines in the figure) of either primitive figure obj1 or obj2 currently being displayed, this stroke is recognized as specifying an erasure and the portions of the primitive figures obj1 and obj2 which correspond to the sequence of handwriting points H are accordingly erased.
