Problems solved by technology

[0007] However, in the technology described in International Publication No. 2001-092973, when the moving image reproduced by the host computer is to be transmitted to the user computer for display, there is a problem that it is subject to fluctuations in the amount of transmitted data or Due to band fluctuations on the network or transmission delay, etc., the operation of displaying images may stop, or part of them may be missing, and smooth animation may not be displayed.
[0008] In addition, in the technique of Japanese Patent Application Laid-Open No. 2007-88960 that partially solves this problem, in a web browser, etc., that adjusts the size to arrange information specifying a plurality of text information, image information, and the arrangement of information thereof according to the content of the information itself , the animation cannot be properly configured

Embodiment approach 1

[0024] The overall configuration of the network computer system according to Embodiment 1 of the present invention will be described with reference to FIG. 1 . FIG. 1 is a configuration diagram showing the overall configuration of the network computer system according to Embodiment 1 of the present invention.

[0025] In FIG. 1, the network computer system is configured such that the host computer 1 can be remotely operated from the user computer 2 through the network 5. In addition, the WWW server 4 for text, still image, animation, information streaming, and the like communicates with the WWW server through proxy execution. Server 4 requests a proxy server 3 connection.

[0026] In FIG. 1, a plurality of host computers 1, user computers 2 and web servers 4 are shown, and only one proxy server 3 is shown. In the following description, only one proxy server 3 is shown. It is also possible to have a plurality of proxy servers 3 . In addition, functions corresponding to the pro...

Embodiment approach 2

[0069] In Embodiment 2, in Embodiment 1, the user selects whether to perform animation playback on the user computer 2 or to perform animation playback through the host computer 1 during playback.

[0070] The configuration of the network computer system of the present embodiment is the same as that of the first embodiment.

[0071] Second, use Figure 6 The operation of content drawing processing in the network computer system according to Embodiment 2 of the present invention will be described. Figure 6 It is a sequence diagram showing the operation of content rendering processing in the network computer system according to Embodiment 2 of the present invention.

[0072] First, as in Embodiment 1, when the web browser 11 has been executed and displayed on the display 27, after clicking a certain place in the web browser 11 from the mouse 28 of the user computer 2, the process similar to that of FIG. 1 is performed. S101 to S103 are processed in the same manner.

Embodiment approach 3

[0087] In the third embodiment, in the second embodiment, the socket 114 is used to generate a screen requesting confirmation from the user.

[0088] The structure of the network computer system of this embodiment is the same as that of Embodiment 1,

[0089] Second, use Figure 7 The operation of content drawing processing in the network computer system according to Embodiment 3 of the present invention will be described. Figure 7 It is a sequence diagram showing the content rendering processing operation of the network computer system according to Embodiment 3 of the present invention.

[0090] exist Figure 7 In addition to the process of generating a screen requesting confirmation from the user by the socket 114 as the operation of the network computer system according to the present embodiment, and the processing by the socket 114 Figure 6 The playback control program 21 of the playback control program 21 performs the same processing as that of the second embodiment ...

Abstract

The present invention relates to a proxy server and a network computer system. 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.

Description

[0001] priority claim [0002] This application has priority to the Japanese patent application JP2007-243551 filed on September 20, 2007. The content of which is incorporated by reference in this application. technical field [0003] The present invention relates to a network dynamic image display technology between computers of a network computer system that receives and sends information about remote operations through a network, and particularly relates to a display information transmission technology for smoothly reproducing animation. Background technique [0004] In a network computer system in which a plurality of computers are connected via a network, a technique for performing remote operations by connecting an operating side computer (hereinafter referred to as a user computer) to another operated side computer (hereinafter referred to as a host computer) has been put into practical use. In the case of remote operation, the contents of the input operation perform...
