Description

  In the present invention, during a call between the telephones, the same content is displayed on the XML content display application of the other telephone by notifying the content address displayed by the own telephone by the XML content display application, and the same screen is viewed. The present invention relates to an interactive content display system, method, and program capable of realizing a function of making a call.

  With the spread of the call control protocol SIP, the telephone function can now be realized as a more advanced function linked with an Internet browser, e-mail, video conferencing, etc. by a PC. As a desktop phone, we are trying to adopt a large-screen color LCD and a browser to absorb the advantages of the PC. However, the convenience of the browser is impaired due to the limitations of the LCD size and input methods, and its functions are utilized. I'm not sure.

  In addition, a high-performance CPU is required to operate the browser, and desktop phones that do not share as much as mobile phones are less advantageous in terms of price. Although a desktop phone having a videophone function has been realized, the drawing speed of image data is often inferior to that of a PC, and if a comparable videophone is made, it is still very expensive.

  As a related prior art, the following Patent Document 1 describes a Web-linked SIP that enables a service provider to realize a highly convenient advanced service in which a Web system and SIP are linked easily and in a short period of time. A service control system is shown.
