Abstract

When, in a network computer system, a Web browser on a host computer acquires information about images or the like from a network or the like, it analyzes the data received in a proxy server, and, in case the details of the data are moving images, transmits substitute images with the same screen size to host computer, and transmits the moving image access information toward user computer. In case substitute images have been transmitted by proxy server, host computer transmits, to user computer, the display position and screen size of the moving images and information indicating Web server saving the moving images. In this way, it is possible, even when a host computer is remotely operated from a user computer via a network and moving images are displayed, to play back the moving images smoothly.

Claims

1. A method for a proxy server connecting an operating-side computer and an operated-side computer via a network and carrying out by proxy requests to a Web server via said network in a network computer system remotely operating said operated-side computer from said operating-side computer, wherein:

a request to said Web server from said operated-side computer remotely operated from said operating-side computer is transmitted by proxy to said Web server;

a reply is acquired from said Web server;

the details of the same acquired reply are analyzed; and

,

in the case the details of the same reply are moving images or images distributed by streaming, separate images occupying the same screen size and including information about access to said moving images or said images distributed by streaming are returned to said operated-side computer.

2. The method according to claim 1, wherein the record of said separate images returned to said operated-side computer is saved as a log and is output as information for charging uses with respect to said operated-side computer.

3. A network computer system connecting an operating-side computer and an operated-side computer via a network and remotely operating said operated-side computer from said operating-side computer;

comprising;

a proxy server transmitting by proxy to a Web server a request from said operated-side computer remotely operated from said operating-side computer to said Web server, acquiring a reply from said Web server, analyzing the details of the same acquired reply, and in case the details of the same reply are moving images or images distributed by streaming, returning separate images occupying the same screen size and including information about access to said moving images or said images distributed by streaming to said operated-side computer; and

wherein;

said operated-side computer, in case said separate images are returned from said proxy server, analyzes said separate images and transmits, to said operating-side computer, the display position and screen size of said moving images or said images distributed by streaming and information about access to said moving images or said images distributed by streaming; and

said operating-side computer, on the basis of information from said operated-side computer, directly accesses and plays back said moving images or said images distributed by streaming, superposes the played back screen on the remote screen from said operated-side computer, and makes a display.

4. The network computer system according to claim 3, wherein:

said operated-side computer carries out a display requesting, from the user of said operating-side computer, a judgment as to whether the playback of said moving images or said images distributed by streaming will be carried out with said operated-side computer or carried out with said operating-side computer.

5. The network computer system according to claim 4, wherein:

said proxy server, on the basis of information about said moving images or said images distributed by streaming, carries out switching between performing the playback, of said moving images or said images distributed by streaming, with said operated-side computer or said operating-side computer.
