Menetelmä ja järjestelmä elektronisen datasisällön muuntamiseksi langattomille laitteille

摘要

Electronic documents such as web pages requested from the Internet by a wireless device 12 are converted at a gateway 14 from a first markup language such as hypertext markup language (HTML) into a second markup language such as wireless markup language (WML) from a wireless application protocol (WAP). The electronic document is converted into a format suitable for display on the wireless device based on device type and preference information supplied by the wireless device. The electronic document is divided into textual elements and non-textual elements (e.g. images) before conversion. A converted document is created from the converted elements. Three separate methods of dividing and converting the original document are described. The invention is also applicable to wireline devices.
