Abstract

The invention addresses the objective of optimizing performance of a media data carrier interpreting device.

This is achieved by a media data carrier interpreting device which comprises means for transforming a machine-interpretable instruction comprised in a media data carrier into a machine-executable code during media content presentation.

Said media data carrier comprises a set of machine-interpretable instructions generated according to a method which comprises the steps of generating a first auxiliary set of instructions corresponding to a set of elements wherein the elements are conform with a template and compiling said first auxiliary instruction set. Then, said compiled first auxiliary instruction set is linked with a compiled second auxiliary instruction set corresponding to said template.

This method removes the need for runtime parsing and therefore frees processing capacity for runtime transformation of the machine-interpretable instructions into machine-executable code.

Claims

1. Method for generating a set of machine-interpretable instructions for storage in a data carrier wherein media content comprised in said data carrier is presented to a user upon execution of the machine-interpretable instructions by a data carrier interpreting device, said method comprises the steps of

generating a first auxiliary set of instructions corresponding to a set of elements wherein the elements are conform with a template;

compiling said first auxiliary instruction set and

generating the set of machine-interpretable instructions by linking said compiled first auxiliary instruction set with a compiled second auxiliary instruction set corresponding to said template.

2. Method according to claim 1, further comprising

the template (SHEET) comprises at least one element definition structuring a way of media content presentation and

the set of element indicates at least one way of media content presentation to be used for presenting media content to the user wherein

the elements comprised in said set of elements comprise one or more attributes for configuration of the indicated ways of media content presentation.

3. Method according to claim 1, wherein

the set of machine-interpretable instructions comprises identifiers of elements and/or attributes and

generating the set of machine-interpretable instructions comprises altering said identifiers.

4. Method according to claim 1, wherein

the compiled second auxiliary set of instructions comprises JAVA classes and

generating said first auxiliary set of instructions comprises generating instantiations of said JAVA classes;

wherein the machine-interpretable instruction set is a JAVA object code.

5. Method according to claim 1, wherein

the template is an XML scheme;

the set of elements is comprised in an XML document following said XML scheme and

generating said first auxiliary set of instructions comprises parsing said XML document according to the XML scheme and instantiating an XML document conform object tree.

6. Method according to claim 1, wherein

the machine-interpretable instructions comprise instructions for media content. rendering and instructions for user interaction.

7. Method according to claim 1, wherein the compiled second auxiliary instruction set is generated by

compiling and executing an additional set of instructions corresponding to said template, wherein

upon execution of said compiled additional set of instructions a second auxiliary instruction set is generated, and

compiling the second auxiliary instruction set.

10. Data carrier for media content, said data carrier comprising a machine-interpretable instruction set generated according to claim 1.

8. Authoring device for generating a set of machine-interpretable instructions for storage in a data carrier wherein media content comprised in said data carrier is presented to a user upon execution of the machine-interpretable instructions by a data carrier interpreting device, said authoring device comprising

a generator for generating a first auxiliary set of instructions corresponding to a set of elements wherein the elements are conform with a template;

a compiler for compiling said first auxiliary instruction set and

a merger for generating the set of machine-interpretable instructions by linking said compiled first auxiliary instruction set with a compiled second auxiliary instruction set corresponding to said template.

9. Media data carrier interpreting device comprising

means for accessing a set of machine-interpretable instructions comprised in said media data carrier;

means for presenting media content comprised in said media data carrier to a user by help of executing machine-executable instructions and

means for transforming a machine-interpretable instruction into a machine-executable instructions during media content presentation and

a memory for storing machine-interpretable instructions and machine-executable instructions;

wherein the means for presenting media content shift media content presentation from being performed by help of interpretation of the machine-interpretable instructions to being performed by help of execution of the respective machine-executable instructions.
