Abstract

Presented is a comprehensive infrastructure for easy procurement, licensing, rendering and display of digital text documents. Basic principle of the invention and the provided infrastructure is to divide the execution of E-reading related processes such as procurement of documents, licensing, rendering and display between two different devices, a mobile unit on one hand and a base station on the other hand. In particular, a cost and energy-efficient variant of an electronic device is described that serves as mobile unit that is especially designed for the display of digital text documents within the provided infrastructure.

Claims

1. A comprehensive system for procuring and displaying digital text documents on a mobile device comprising the following components:

mobile unit, designated for the display of electronic text documents comprising

display

memory

microcontroller/display-controller

interface to the base station

energy source

base station, comprising at least

data interface

data storage

data processing unit

interface to the mobile unit

energy source

wherein a document is received by the base station via a data interface, stored in the data storage of the base station and document pages are converted in the data processing unit of the base station to a file format that is displayable by the mobile unit where it is sent to via an interface to be displayed on the mobile unit.

2. A system as described in claim 1 wherein the mobile unit is linked to a unique ID to enable licensing and access provisions of the documents that are to be displayed.

3. A system as described in claim 1 wherein the mobile unit contains an electrophoretic display.

4. A system as described in claim 1 wherein the mobile unit contains a touch sensitive display (touchscreen).

5. A system as described claim 1 wherein the mobile unit contains a non-volatile memory to store one or more documents.

6. A system as described in claim 1 wherein the data interface between base station and mobile unit is of wireless technology and data is transmitted via radio from the base station to the mobile unit.

7. A process carried out by the means of the infrastructure as described in claim 1 wherein a document is received by the base station via a data interface, stored in the data storage of the base station and document pages are converted in the data processing unit of the base station to a file format that is displayable by the mobile unit where it is sent to via an interface to be displayed on the mobile unit.

8. A process described in claim 7 wherein files that are to be transmitted from the base station to the mobile unit are compressed before transmission.

9. A process described in claim 7 wherein files that are to be transmitted from the base station to the mobile unit are encrypted before transmission and decrypted on the mobile unit.

10. A process described in claim 7 wherein navigation on the mobile unit is established via a remote user interface on the base station.
