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.

Claims

1. An image data processing system for generating an executable animation file, comprising:

data storage means storing first graphical data, second graphical data and rendering instructions; and

processing means configured to combine said first graphical data and said rendering instructions, wherein

said second graphical data comprises unlocked parameters defining second characteristics of said animation;

said first graphical data comprises locked parameters defining first characteristics of an animation and references to said unlocked parameters;

said combining process results in an executable animation file being generated, containing within it references to said unlocked parameters, such that;

said first animation characteristics are editable only at a first level of user access, prior to said combination of first graphic data and rendering instructions; and

said second animation characteristics are editable at a second level of user access, after said combining has taken place.

2. An image data processing system according to claim 1, wherein said processing means is configured to execute steps to scramble the first graphic data contained in the executable file.

3. An image data processing system according to claim 1, wherein said second graphical data comprises metadata, and for each of a plurality of unlocked parameters said metadata contains a specific value and an identifying means for identifying the corresponding unlocked parameter, to allow the construction of an interface for said unlocked parameters for user modification of said second animation characteristics.

4. An animation editing system according to claim 3, wherein said identifying means is a description of the corresponding parameter.

5. An animation editing system according to claim 3, wherein said metadata includes a defined range of permissible values for each parameter.

6. An animation editing system according to claim 3, wherein said metadata is encoded in XML (Extensible Markup Language).

7. An animation editing system according to claim 3, wherein said system is configured to transmit said metadata over a computer network separately from said graphic data.

8. An animation editing system according to claim 1, wherein said animation file is executable only before a defined date.

9. An animation editing system according to claim 1, wherein said rendering instructions include instructions to combine said rendered animation with other moving image data.

10. A method of generating an executable animation file in an image data processing system, in which first graphical data, second graphical data and rendering instructions are stored upon a data storage medium and these are processed by processing means in accordance with processing instructions to combine said first graphical data with instructions to generate an executable animation file, in which:

said first graphical data comprises locked parameters defining first characteristics of an animation and references to second characteristics of said animation;

said second graphical data comprises unlocked parameters defining said second characteristics of said animation;

wherein

said combining process results in an executable animation file being stored, containing within it references to said unlocked parameters, such that;

said first animation characteristics are locked by said combining process and are editable only at a first level of user access, prior to said combination of first graphic data and rendering instructions; and

said second animation characteristics are editable at a second level of user access, after said combining has been performed.

11. A method of generating an executable animation file according to claim 10, wherein said processing means is configured to execute steps to scramble the first graphic data contained in the executable file.

12. A method of generating an executable animation file according to claim 10, wherein said second graphical data comprises metadata, and for each of a plurality of unlocked parameters said metadata contains a specific value and an identifying means for identifying the corresponding unlocked parameter, to allow the construction of an interface for said unlocked parameters for user modification of said second animation characteristics.

13. A data structure on a machine-readable medium, containing instructions for processing means in an image data processing system comprising said processing means and data storage means, in which said instructions instruct said processing means to perform processing operations for generating an executable animation file, by combining first graphical data stored upon said data storage means with rendering instructions, and for generating a second graphical data file, wherein

said first graphical data comprises locked parameters defining first characteristics of an animation and references to second characteristics of said animation;

said second characteristics being defined by second graphical data comprising a plurality of unlocked parameters;

wherein

said combining process results in an executable animation file being generated, containing within it references to said unlocked parameters, such that;

said first animation characteristics are editable only at a first level of user access, prior to said combination of graphic data and rendering instructions; and

said second animation characteristics are editable at a second level of user access, after said combining has taken place.

14. A data structure on a machine-readable medium according to claim 13, wherein said instructions instruct said processing means to execute steps to scramble the first graphic data contained in the executable file.

15. A data structure on a machine-readable medium according to claim 13, wherein said second graphical data comprises metadata, and for each of a plurality of unlocked parameters said metadata contains a specific value and an identifying means for identifying the corresponding unlocked parameter, to allow the construction of an interface for said unlocked parameters for user modification of said second animation characteristics.

16. An image processing system for generating animated visual images, including processing means and data storage means, in which an executable animation file and a editable data file are stored upon said data storage means, wherein

said executable animation file includes rendering instructions and animation data which in combination define first characteristics of an animation, said animation data including locked animation parameters and references to unlocked animation parameters;
