Abstract

A portable communication device equipped with a screen and a random access memory. The device receives a data stream through a radio link for automatically displaying information from the data stream on a display screen, without any user's request, a part of this information being stored in random access memory during a period of time that is longer than the duration of display and displays information from the data stream on the display screen, upon user's request, this information being stored in random access memory during the duration of display only.

First claim

The invention claimed is:

1. A portable communication device equipped with a display screen and a random access memory comprising:
an antenna configured to receive a data stream through a radio link;
a processor configured to work with the random access memory to automatically display information from the data stream on said display screen, a part of the information being stored in the random access memory during a period of time that is longer than the duration of the display;
said processor and said random access memory being further configured to display information from the data stream on said display screen upon request, the requested information being stored in the random access memory only during the duration of the display.

2. The portable communication device according to claim 1 , wherein the processor and the random access memory are further configured to successively display information from the data stream on said display screen.

3. The portable communication device according to claim 1 , wherein the processor and the random access memory are further configured to display, in parallel, on a split screen, information from said data stream on said display screen.

4. The portable communication device according to claim 1 , wherein the received data stream is formatted according to textual and graphical elements.

5. The portable communication device according to claim 4 , wherein the data stream received from the radio link is formatted according to two models of said textual and graphical elements, a first model for the display of information absent a request and a second model for the display of information upon request.
