## Abstract

Mobile devices enabled to support resolution-independent scalable display of Internet (Web) content to allow Web pages to be scaled (zoomed) and panned for better viewing on smaller screen sizes. The mobile devices employ software-based processing of original Web content, including HTML-based content, XML, cascade style sheets, etc. to generate scalable content. The scalable content and/or data derived therefrom are then employed to enable the Web content to be rapidly rendered, zoomed, and panned. Display lists may also be employed to provide further enhancements in rendering speed. Context zooms, including tap-based zooms on columns, images, and paragraphs are also enabled.

## Claims

### Claim 5 (depends on 1)

The method of claim 1, wherein the Web page includes at least one hyperlink, the method further comprising:
enabling a user to select a hyperlink via the touch-sensitive display; and, in response thereto,
retrieving and processing HTML-based Web content and the CSS content associated with the hyperlink to translate the HTML-based Web content and the CSS content associated with the hyperlink into an additional scalable vector representation; and
employing the additional scalable vector representation and/or data derived therefrom to render the Web content and the CSS content associated with the hyperlink on the touch-sensitive display.

### Claim 6 (depends on 1)

### Claim 8 (depends on 1)

The method of claim 1, wherein the HTML-based Web content includes at least one image, the method further comprising enabling a user to zoom on an image by tapping on the image via the touch-sensitive display, wherein in response thereto, the display is re-rendered such that the image is displayed to fit a width of a display area of the touch-sensitive display, the display area used for displaying the HTML-based Web content.

### Claim 9 (depends on 1)

The method of claim 1, wherein HTML code in the HTML-based Web content of the Web page defines a Web page width, the method further comprising:
interpreting the HTML code to determine the Web page width; and
rendering a view of the Web page wherein the Web page width is rendered to fit across a width of a display area of the touch-sensitive display, the display area used for displaying Web page content.

### Claim 10 (depends on 9)

The method of claim 9, wherein under the first view the Web page width is rendered to fit across the width of the display area of the touch-sensitive display, the display area used for displaying the HTML-based Web content.

### Claim 11 (depends on 1)

### Claim 14

A method, comprising:
requesting through a mobile device having a touch-sensitive display a Web page comprising HTML-based Web content including HTML code for at least multiple columns and Cascading Style Sheets (CSS) content;
retrieving and processing the HTML-based Web content including the HTML code for the at least multiple columns and the CSS content at the mobile device to generate a scalable vector representation of the Web page;
rendering the Web page on the touch-sensitive display utilizing the scalable vector representation to produce a first view of the Web page at a first zoom level that preserves the original page layout, functionality and design defined by the HTML-based Web content including the at least multiple columns and the CSS content relative to the original page layout, functionality and design defined by the HTML-based Web content including the at least multiple columns and the CSS content when rendered by a commercially available desktop browser; and
re-rendering the Web page utilizing the scalable vector representation in response to associated user inputs to iteratively zoom in and out views of the Web page at multiple different zoom levels while preserving the original page layout, functionality, and design defined by the HTML-based Web content including the multiple columns and the CSS content relative to the original page layout, functionality and design defined by the HTML-based Web content including the at least multiple columns and the CSS content when rendered by the commercially available desktop browser; and
