Embedded HTML documents downloaded and displayed simultaneously with primary HTML document
First Claim
1. A method for rendering first and second html documents comprising respective first and second sets of html data to a display screen, wherein the first html document references the second html document, the method comprising the steps of:
- parsing and rendering the first set of html data to a first area of said screen, said first set of html data including an applet tag defining a second area of said screen in which to render said second html document, wherein said second area is embedded within said first area;
wherein said applet tag further references a parsing and rendering applet forparsing and rendering to said second area of said screen the second set of html data substantially concurrent with rendering of said first html data.

Abstract
The present invention relates to embedded HTML documents and to a method and system for rendering such documents to a visual display unit. The Internet does not currently support embedded documents. The current manner of viewing a plurality of HTML documents is to include a URL within one documents which allows access to a second document. HTML does not provide for the nesting or embedding of HTML documents. Accordingly the present invention provides a system and method for realising embedded HTML documents. The present invention utilises a Java applet which can be launched by a Java enabled browser. The Java applet can parse and render HTML instructions contained within an HTML document to a reserved area of a visual display unit. The Java applet can also launch further applets and therefore allow further nesting or embedding of HTML documents.

12. A computer program product on a computer readable medium comprising a multi-leveled document object comprising a first level of html data, and a second level of html data embedded within or accessible from said first level, said first level of html data including an applet tag containing a reference to an html parsing and rendering applet for receiving a reference to the second html document and parsing and rendering said second level of html data within a predeterminable area of said first level of html data for display on said screen substantially concurrent with rendering of said first html data.

13. A computer program product on a computer readable medium for rendering first and second html documents comprising first and second sets of html data to a display screen, wherein the first html document has embedded therein the second html document, comprising:
-
means for parsing and rendering the first set of html data to a first area of said screen, said first set of html data including an applet tag defining a second area of the screen in which to render said second html document, wherein said second area is embedded within said first area; and means responsive to said applet tag for parsing and rendering to said second area of said screen the second set of html data. - View Dependent Claims (14, 15, 16)
