Compact graphical interactive information system
First Claim
1. In a system including a plurality of reception components having defined display capabilities, at least two of the plurality of reception components having different display capabilities, a method of providing a graphical interactive information application for display to, and control by, a user, comprising the steps of:
- broadcasting at least one graphical object definition record comprising hint information describing optional image characteristics of a graphical object;
receiving the broadcast graphical object definition record and hint information at each of the plurality of reception components; and
creating different graphical interactive information displays on ones of the plurality of reception components having different display capabilities based upon the broadcast graphical object definition record and using the hint information to selectively display the graphical object with the optional image characteristics supported by the capabilities of the reception components.

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.

13. In a system including first and second reception components having different display capabilities, a method of decoding a broadcast signal comprising the steps of:
-
receiving the broadcast signal at the first and second reception components; extracting at the first and second reception components an executable graphical interactive information system application including at least one image and hint information describing optional characteristics of the image; executing the graphical interactive information system application on the first reception component to generate the at least one image for display on a first display device coupled to the first reception component; executing the graphical interactive information system application on the second reception component to generate the at least one image for display on a second display device coupled to the second reception component; selectively adapting the generation of the at least one image to the display device of the first reception component based upon the hint information and the display capabilities of the first reception component; and selectively adapting the generation of the at least one image to the display device of the second reception component based upon the hint information and the display capabilities of the second reception component, wherein the at least one image displayed on the first display device is different than the at least one image displayed on the second display device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for providing a graphical interactive information application describing at least one image to a plurality of reception components having defined display capabilities, at least two of the plurality of reception components having different display capabilities, the method comprising the step of:
-
broadcasting at the least one graphical object definition record describing at least one image and comprising hint information describing optional characteristics of the at least one image to the plurality of reception components; wherein ones of the plurality of reception components having different display capabilities create different graphical interactive information displays based upon the broadcast graphical object definition record and using the hint information to selectively display optional characteristics of the at least one image supported by the reception components.
