Abstract: A method of customising an animation. A broadcast station renders first animated objects in response to locked graphic data and unlocked metadata. The metadata facilitates customisation, by including parameter interface information as well as actual parameter values, so that the first animation objects can be customised without reference to the locked graphic data. A distribution station receives signals from the broadcaster, and cumulatively renders second animated objects in response to second locked graphic data and second unlocked metadata, the latter of which is modified in response to distributor data. A television receives signals from the distributor, and cumulatively renders third animated objects in response to third locked graphic data and third unlocked metadata, which is modified in response to viewer data.

Abstract: A method for modifying characteristics of an animation. An animation is created for a live broadcast and comprises graphic data including first parameters and references to editable parameters. The editable parameters have their characteristics, including a value and a description for each editable parameter, stored as metadata. The graphic data is instantiated by a metafile containing the metadata to determine the overall characteristics of an animation used during the live broadcast. The metadata may be independently modified on remote processing systems without having access to said graphic data. Finally, the animation is rendered during a broadcast, during which both the first and editable parameters are used to determine characteristics of the rendered animation.

Abstract: A method of generating an executable graphic file for an animation. Graphic data defines first characteristics of an animation, which are accessible via locked parameters at a first level of user access. The graphic data also contains references to unlocked parameters stored as metadata in a metafile. The metadata preferably includes, for each unlocked parameter, a value field, a range of possible values and a description, thus making it possible to construct a user interface to modify second animation characteristics without modifying the graphic data. The graphic data is combined with rendering instructions, to form an executable animation file. Preferably the executable file cannot execute after a predetermined date. Multiple instances of the animation may be created by re-use and modification of the original metafile.
