Abstract

A method for transmitting hyperlinked information and a display content distribution system for transmitting individualized content to multiple users. A display content source is accessed by a gateway server for obtaining display content including images of hyperlinked information. For example, an Internet server can be connected to through a modem and HTML code of a web page with hyperlink information downloaded. The location of images of the hyperlinked information in the display content is determined to map the images of the hyperlinked information to a remote display screen, and to generate mapped hyperlink data. That is, the images of the hyperlinks are mapped to the location of where they will be displayed on the remote display screen. The mapped hyperlink data is stored. The HTML page is converted into a frame of video information and modulated with a carrier frequency to create a displayable content video signal containing the display content. This displayable content video signal is transmitted to the remote display screen. Since the gateway server performs the processing of the HTML document and generates a video frame of display information, the remote display screen is relieved of substantial processor overhead. Even though the remote display screen does not store or process the HTML code, a user can still activate a displayed hyperlink by clicking on the image of the hyperlinked information. The remote display screen detects the screen location that is clicked on and generates a user input signal. This user input signal is wirelessly transmitted and received by the gateway server. A function to be performed is determined in response to the user input signal be comparing the user input signals with the stored mapped hyperlink data. The gateway server then performs the determined function.
