Definitions

  • the present invention relates to a system and method for content analysis and minimization, and in particular, for a system and method for minimizing specific types of content, such as graphical images and animation, thereby decreasing the amount of data which must be downloaded.
  • Web pages are documents written in a mark-up language, such as HTML (HyperText Mark-up Language), XML (Extended Mark-up Language) or VRML (Virtual Reality Modeling Language) for example.
  • Web pages are displayed as a single unit through a Web browser, which is a software program specially adapted for displaying such mark-up language documents.
  • Web pages are combinations of several different types of data, stored in different file formats. For example, graphical images are typically stored as JPEG or GIF format files. These different types of data are then combined by the Web browser for display as a single unit.
  • a single Web page may contain a large amount of data, and therefore may require significant bandwidth to download from a Web server on the Internet.
  • the amount of data is typically related to the amount of graphical image data and/or animation or streaming video data which is associated with the Web page. For example, if a Web page contains many graphical images, the amount of associated data may be significantly increased than for Web pages which are "text-only".
  • animation and/or streaming video data also require a significant amount of bandwidth, particularly if such data is presented as "moving" or animated images, rather than in a static, non-moving display.
  • For users with a low bandwidth connection to the Internet such a large amount of data may be extremely frustrating to download, as it may require a significant amount of time. Indeed, slow downloading of Web pages may even cause the user to simply stop the process of downloading, such that the user does not even see the Web page display by the Web browser.
  • Such a solution would preferably also not require client-side software, such that the user would not need to install an applet or other software for operation with the Web browser. Furthermore, such a solution would also preferably automatically parse and minimize the content of Web pages, such that the minimized Web pages could be produced substantially without manual intervention. There is thus a need for, and it would be useful to have, a system and a method for selectably reducing the amount of bandwidth required to download Web pages, thereby increasing the speed for downloading such Web pages, while still maintaining the ability of the user to view all of the components of the Web pages, without any special software installed at the client (user) computer.

  • the present invention is of a method and a system for reducing the amount of bandwidth, and hence the amount of time, required to download Web pages, while still maintaining the ability of the user to view all components of the Web page.
  • the components of the Web page are selectively minimized, for example by reducing the size of graphical image components, by only displaying animation and/or video stream data as static images, and so forth.
  • the Web page is preferably automatically parsed and selected components minimized.
  • the minimized Web page may then be stored, for example by the owner of the Web page, until requested by the user.
  • the Web page may be minimized automatically and dynamically, "on the fly", for example by an ISP (Internet Service Provider).
  • ISP Internet Service Provider
  • the user is able to indicate a preference for the minimized Web page or for the "full" Web page (without minimized components), for example by "clicking" or otherwise selecting an icon on the Web page.
  • Such an icon is preferably the first, or one of the first, components of the Web page which is served to the user computer, thereby enabling the user to immediately select the minimized version if desired.
  • the user is able to indicate such a preference without the installation of additional software, such as an applet, on the user computer.
  • the user is able to request the display of the full (non-minimized) Web page at any time.
  • Various components of the Web page may optionally be minimized.
  • minimizing graphical images is relatively simple, as the images only need to be reduced in size for a significant reduction in the total amount of data for each image.
  • the image file format may be converted to a different file format, which may result in the reduction in the amount of image data, for example when converting from a non-lossy image file format to a lossy format.
  • the moving images may be replaced with a single static, still frame, as the elimination of motion also results in a significant reduction in the total amount of data for each animation and/or video stream component.
  • any type of dynamic object with motion attributes may be minimized by such a conversion to a static, still frame.
  • minimization include, but are not limited to, changing the color depth of images, changing the resolution of images and dithering.
  • the Web page including associated Java applets, scripts and other associated software objects, is parsed for the automatic conversion to the minimized version.
  • Dynamically selectable objects such as Java applets, are preferably only minimized when the Web page components are minimized dynamically or "on the fly".
  • the process of minimization at least includes the step of minimizing components, such as graphical images, which are associated with the software object. More preferably, the process of minimization also includes the step of altering the software object itself, for example by reducing the activities performed by the software object, or even by preventing the operation of the software object.
  • the advantage of the present invention is that selected, specific types of Web page components are minimized, in order to permit more efficient downloading of the entire Web page.
  • Graphical Web page components tend to be particularly large. Since graphical image Web page components typically compose about eighty percent of the overall size of the Web page data, minimizing these components by a factor of fifty percent would result in an overall minimization of forty percent, for example. Thus, the minimization of the Web page components by a particular order of magnitude would typically result in a minimization of the size of the Web page by a similar order of magnitude.

Abstract

L'invention concerne un procédé et un système de réduction de la quantité de bandes passantes et donc, de la quantité de temps nécessaire pour télécharger des pages Web, tandis que l'on maintient la capacité d'un utilisateur à visionner tous les composants de la page Web. Lesdits composants sont minimisés de manière sélective, par exemple par réduction de la taille des composants d'images graphiques, par le biais uniquement de l'affichage de données de flux vidéo et/ou d'animation en tant qu'images statiques, et ainsi de suite. La page Web est de préférence automatiquement analysée et les composants sélectionnés minimisés. La page Web minimisée peut être stockée, par exemple par le propriétaire de la page Web, jusqu'à ce qu'elle soit demandée par l'utilisateur. Selon un autre mode de réalisation, la page Web peut être minimisée automatiquement et dynamiquement, 'au vol', par exemple par un fournisseur de services Internet. Ainsi, l'utilisateur peut visionner la page Web dans sa globalité par le biais du navigateur Web, tandis qu'il apprécie la performance améliorée qui se traduit par une réduction du temps de téléchargement et des besoins en bandes passantes.
