Abstract
Abstract The invention discloses a portable remote device that allows the user to access the Internet and World Wide Web. The portable device connects to a cellular telephone, thus providing wireless connection to the internet via a host computer which runs a browser, that takes information received from the Internet or other sources and renders it onto a virtual display in its memory. This information is directed to software, which reduces the color depth of the information to a lower depth color image. This reduced image is then compressed and encrypted by another software and sent to the portable device of the invention, which decrypts and decompresses it for displaying to the user. The browser may also reduces the color depth and compress the image without need for further software. Thus, the user views a bit map or raster image of a Web page, which is stored into memory. The portable device further comprises methods of pointing and clicking on text and images which represent links to other pages. Web pages with links may also be sent to the portable device, which stores them into memory to facilitate off-line viewing from the memory of the device. The user may also select desired links to each web page. Email messages may be retrieved manually or automatically at programmed times. Video frames and sound files may also be displayed on the portable device, with the aid of a buffer memory to facilitate uninterrupted playback.
