Abstract: A display control unit that is used to display a current portion of a document on a screen when an interactive or scrollable page of said document requires a larger display area than that of the screen. The display control unit includes a unit which is connected to a remote server configured to deliver interactive documents including principal and secondary documents. The display control unit also includes a display unit used to control the display of a current portion of the scrollable interactive page on the screen, and a memory control unit including a priority level allocation unit configured to assign a priority level to each secondary document of the scrollable interactive page and a memory control unit used to control the storage of secondary documents with the highest priority levels in the memory.

Abstract: The invention concerns a method for displaying a document on a display screen capable of being subjected to a scroll procedure, involving the following steps: providing the document with an amount of graphic memory to create a buffer memory of the visible part of the document and zones nearest to said visible part; calculating and cutting out into pixmaps said memory; relatively positioning said pixmaps with respect to the entire document and its visible part; filling up the content of the pixmaps, when the document is subjected to a display or scroll procedure, recopying the pixmap content in the display window; and repeating the relative positioning of the pixmaps with respect to the document.

Abstract: The invention relates to a display control unit which is used to display a current portion of a document on a screen (15) when an interactive or scrollable page of said document requires a larger display area than that of the screen. The inventive unit consists of: a unit (10) which is connected to a remote server (12), said server (12) delivering interactive documents comprising principal and secondary documents; a display unit (14) which is used to control the display of a current portion of the scrollable interactive page on the screen (15); and a memory control unit (18) comprising (i) a priority level allocation unit (30) which is used to assign a priority level to each secondary document of the scrollable interactive page and (ii) a memory control unit (31) which is used to control the storage of secondary documents with the highest priority levels in the memory (17).

Abstract: Aspects of the present invention relate to a method of controlling the appearance of a graphical object in a graphical user interface. In an embodiment of an aspect of the invention, an object, such as a widget, in a graphical user interface comprises an instance of a widget class in which arr defined properties and/or methods which control operation of the object; and an associated instance of a look object class in which are defined properties and/or methods which control the look of the object.

Abstract: Apparatus and a method are disclosed for facilitating navigation between objects to be presented on a display, particularly objects defined in a document such as an HTML document, without use of a pointing device. Preferred embodiments are particularly suited to navigation between hyperlinks of a web page displayed by a receiver/decoder using arrow keys on a remote control.
