Abstract

A method and apparatus for generating a non-linear narrative article. After generation of a non-linear narrative article from a set of narrative rules and accompanying media elements, the narrative is optimised and the media elements are also optimised into a dictionary. A narrative tree generator determines all possible paths through the narrative to generate a narrative tree and redundant parts are removed.

Claims

1. A method of generating a digital media non-linear narrative article comprising the steps of:

processing a non-linear narrative data structure comprising a set of media elements and a set of narrative rules specifying the order in which the media elements in said set can be presented to a viewer of the non-linear narrative article;

generating a narrative tree data structure from the set of narrative rules, the narrative tree data structure having a set of nodes corresponding to the set of rules and a set of branches representing the media elements,

analysing the narrative rules within the narrative tree data structure to identify subsets of rules defining sequences of media elements which can be presented contiguously;

for each subset, processing the media elements represented by the branches in the narrative tree;

storing the generated narrative tree data structure and processed media elements.

2. A method according to claim 1, wherein the processed media elements are stored in a data store separately from the narrative tree data structure and further comprising replacing the media elements stored in the narrative tree data structure with a reference to the location of the corresponding media element in the data store.

3. A method according to claim 1, wherein the sequences of media elements are combined and rendered as a single media element.

4. A method according to claim 1, further comprising optimising the narrative tree data structure by identifying commonality between the subsets of rules and collapsing those sections of the narrative tree data structure together.

5. A method according to claim 4 further comprising identifying duplicate processed media elements in the data store;

removing duplicates and replacing references in the narrative tree data structure to refer to the location of the respective remaining processed media element in the data store.

6. A method according to claim 1, wherein the media elements are audio, video or audio-visual media clips.

7. A method according to claim 2, further comprising identifying different types of media element within the non-linear data structure and storing each of the different media element types in a different data store

8. Apparatus for generating a digital media non-linear narrative article comprising:

non-linear narrative processing means for processing a non-linear narrative data structure comprising a set of media elements and a set of narrative rules specifying the order in which the media elements in said set can be presented to a viewer of the non-linear narrative article;

generating means for generating a narrative tree data structure from the set of narrative rules, the narrative tree data structure having a set of nodes corresponding to the set of rules and a set of branches representing the media elements,

analysing means for analysing the narrative rules within the narrative tree data structure to identify subsets of rules defining sequences of media elements which can be presented contiguously;

media element processing means for processing, for each subset, the media elements represented by the branches in the narrative tree; and

a data store for storing the generated narrative tree data structure and processed media elements.

9. Apparatus according to claim 8, wherein the data store stores the processed media elements separately from the narrative tree data structure and wherein the generating means is arranged to replace the media elements stored in the narrative tree data structure with a reference to the location of the corresponding media element in the data store.

10. Apparatus according to claim 8, wherein the media element processing means is arranged to combine and render sequences of received media elements as a single media element in the data store.

11. Apparatus according to any of claims 8, further comprising optimising means for optimising the narrative tree data structure by identifying commonality between the subsets of rules and collapsing those sections of the narrative tree data structure together.

12. Apparatus according to claim 11 wherein the optimising means is further arranged to identify duplicate processed media elements in the data store;

remove duplicates and replace references in the narrative tree data structure to refer to the location of the respective remaining processed media element in the data store.

13. Apparatus according to claim 8, wherein the media elements are audio, video or audio-visual media clips.

14. Apparatus according to claim 8, wherein the generating means is further arranged to identify different types of media element within the non-linear data structure and store each of the different media element types in a different data store.
