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.

Claims

1. A computer program product comprising a computer storage medium storing a computer program code mechanism which when executed by a computer, causes the computer to perform a method, comprising:

obtaining multi-dimensional parameters relating to a service of sending or receiving data via a network, the parameters being represented as numeric values normalized by base units and indicating capabilities of another computer remote from the computer, wherein the parameters include at least a link speed relating to the service of sending or receiving data via the network and a horizontal and vertical size of a display of the another computer, and the base units are kilobits per second (kbps) corresponding to the link speed parameter, and a number of pixels corresponding to each of the horizontal and vertical size of the display of the another computer; and

generating detailed information representing content of the service of sending or receiving data via the network by the parameters obtained, wherein the detailed information represents capabilities of the another computer and is employed for confirming availability of the service of sending or receiving data via the network.

2. The computer program product according to claim 1, wherein the obtaining step divides the parameters into a plurality of regions based on a main-factor parameter that restricts coexistence with other parameters, and obtains the parameters for each of the regions.

3. The computer program product according to claim 2, wherein the obtaining step obtains the multi-dimensional parameters for each of the regions as one-dimensional integer values, respectively.

4. The computer program product according to claim 3, wherein the generating step represents the detailed information by a combination of the integer values and logic symbols.

5. The computer program product according to claim 4, wherein the generating step uses a first symbol representing selection of one of the plurality of integer values and a second symbol representing a set of the integer values.

6. The computer program product according to claim 5, wherein the generating step uses, as the second symbol, a start value representing a start of a range, an end value representing an end of the range, and a step defining a change width between the start value and the end value.

7. The computer program product according to claim 1, further comprising the steps of:

obtaining an identifier for identifying the service of sending or receiving data via the network; and

adding the identifier to the detailed information representing content of the service of sending or receiving data via the network.

8. The computer program product according to claim 7, further comprising:

a first sending step of sending the identifier to a specified destination via the network.

9. An information processing method for an information processing apparatus, comprising:

obtaining multi-dimensional parameters relating to a service of sending or receiving data via a network, the parameters being represented as numeric values normalized by base units and indicating capabilities of another computer remote from the computer, wherein the parameters include at least a link speed relating to the service of sending or receiving data via the network and a horizontal and vertical size of a display of the another computer, and the base units are kilobits per second (kbps) corresponding to the link speed parameter, and a number of pixels corresponding to each of the horizontal and vertical size of the display of the another computer; and

generating detailed information representing content of the service of sending or receiving data via the network by the parameters obtained, wherein the detailed information represents capabilities of the another computer and is employed for confirming availability of the service of sending or receiving data via the network.

10. An information processing apparatus comprising:

an interface configured to obtain multi-dimensional parameters relating to a service of sending or receiving data via a network, the parameters being represented as numeric values normalized by base units and indicating capabilities of another computer remote from the computer, wherein the parameters include at least a link speed relating to the service of sending or receiving data via the network and a horizontal and vertical size of a display of the another computer, and the base units are kilobits per second (kbps) corresponding to the link speed parameter, and a number of pixels corresponding to each of the horizontal and vertical size of the display of the another computer; and

a processor configured to generate detailed information representing content of the service of sending or receiving data via the network by the parameters obtained, wherein the detailed information represents capabilities of the another computer and is employed for confirming availability of the service of sending or receiving data via the network.
