Abstract
A method and apparatus allows an information provider to broadcast a graphical interactive information system application to a user even using a low-bandwidth transport such as the VBI. A compact protocol encapsulates graphical information using definitions of graphical objects and resources. A scripting and command language is also highly compact. A reception component receives the compact protocol and displays and operates a complete graphical interactive information system application.
