Abstract: PROBLEM TO BE SOLVED: To provide a method, apparatus and system for dynamically adjusting transcoding parameters to increase the benefits of transcoding. SOLUTION: Methods of adaptation are designed to cope with the variability of network characteristics and of the size of transcoded images. This invention also provides a method and apparatus to enable the transcoding proxy to adjust a quality-size tradeoff on a per-image and/or a per-client basis. An adaptive transcoder chooses different parameters for each object, and provides performance improvement. The invention further provides a general framework for making policy decision taking into account available bandwidth, content and type of image, and user preferences. The invention also includes methods for generating feedback about the choice of optimal transcoding parameters to the user. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method and device and system for dynamically adjusting an exchange coding parameter for increasing the merits of exchange coding. SOLUTION: An appropriating method is designated for processing network characteristics and the variety of the size of an image to be exchange-coded. Also, the trade-off of quality and size can be adjusted for each image or client 230 by an exchange coded proxy. An appropriate exchange coder selects a different parameter for each object for improving performance. Moreover, policy decision is operated by a general frame work under the consideration of valid band width, image contents and type, and user selection. Also, feedback related with the selection of the optimal coding parameter is generated for a user.

Abstract: PROBLEM TO BE SOLVED: To make it easy for a general computing device to display web contents by changing elements in an HTML file by using information included in a retrieved content modification file. SOLUTION: When the general computing device requests an HTML file (B100), the HTML file is analyzed and a link to a content-modified file including information regarding the modification of elements in the HTML file is discriminated so that the file can be displayed by the general computing device (B200). Then the link is used to retrieve the discriminated content-modified file (B300). The information in the retrieved content-modified file is used to change selected elements of the HTML file so that the file is displayed by the reqeust-side general computing device (B600).
