Abstract

Methods and apparatus are provided for user interaction with a branch-structured narrative entertainment, where user input influences the selection of paths at branch points. A user interface (14) holds a record of the narrative structure (48) with the audio and video components being called up from remote or local storage as required. A record is kept (52) of previous user interactions during a narrative and, for one or more branch points, path selection is made by the apparatus at least partially on the basis of the accumulated record.

Claims

1. Interactive entertainment apparatus operable to output sequences of image frames comprising a user-influenced path through a branch structured narrative, the apparatus comprising:

a source of image frames for all branch structure paths of the narrative;

branch storage means for data defining the narrative branch structure;

user operable input means;

branch selection means coupled to the branch store and operable to detect narrative branch points and to call one of two or more image frame sequences from the image frame source in dependence on the user input;

an output for the selected image frame sequences; and

interaction memory means arranged to receive and store data relating to user input,

the branch selection determining which of said two or more image frame sequences to call on the basis of at least two preceding and separate user inputs.

2. Apparatus as claimed in claim 1, wherein said interaction memory means comprises a non-volatile storage device.

3. Apparatus as claimed in claim 2, further comprising a smart card reader operable to access data stored in a memory of a smart card and to write data thereto, wherein said interaction memory means comprises said memory of said smart card.

4. Apparatus as claimed in claim 3, wherein said received image data is in encrypted form and requires one or more key codes for decryption thereof, wherein said key code or codes are stored on said smart card, and the apparatus further includes decryption means coupled to receive the encrypted signal and connected to access key code or codes on the smart card through the smart card reader.

5. Apparatus as claimed in claim 1, further comprising image generating means operable to generate and output image frames on the basis of received data from said image frame source.

6. Apparatus as claimed in claim 5, wherein said source of image frames provides sequences of video frames and said image generating means is operable to generate image artefacts overlying one more of the video frames when said frames are displayed.

7. Apparatus as claimed in claim 5, wherein said source of image frames provides animation source data and said image generating means is configured to generate and render successive animated image frames in accordance with said source data.

8. Apparatus as claimed in claim 1, wherein said source of image frames comprises a remote source coupled to said apparatus via a data transmission network, and said apparatus is operable to generate and send messages requesting image data via said network.

9. Apparatus as claimed in claim 8, wherein said remote source provides image frames and ancillary data in multiplexed arrangement on a single channel of the network, the apparatus further comprising a demultiplexer arranged to receive signals from said network channel and separate the respective components thereof.

10. Apparatus as claimed in claim 8, wherein a further data source is provided local to the apparatus and said apparatus is operable to control the accessing of data therefrom.

11. Apparatus as claimed in claim 1, wherein said source of image frames comprises an optical disc accessed via a disc reader, and said apparatus is further operable to control access of data from the disc by the reader.

12. A smart card for use with apparatus as claimed in claim 2, the card including a write/read memory area including said interaction memory.

13. An optical disc for use with an apparatus as claimed in claim 11, said disc carrying data defining the narrative structure, a plurality of image frame data segments arranged on the disc at predetermined locations and an addressing table specifying to the apparatus access addresses for each image frame data segment.

14. An interactive entertainment source apparatus operable to supply image frames to one or more apparatuses as claimed in claim 1, said source apparatus including means for monitoring and logging apparatus frame sequence calls for branch points of the interactive entertainment, means for determining the frame sequence to be sent on the basis of said frame sequence calls, and transmission means operable to transmit selected ones of the frame sequences.

15. A source apparatus as claimed in claim 14, comprising counter means arranged to determine numbers of requests for each particular one of alternate possible frame sequences, and the transmitted one of those frame sequences is determined by majority vote.

16. A source apparatus as claimed in claim 15, wherein said means for monitoring and logging maintains a record of two or more past branch point interactions and includes arithmetic means operable to generate a weighting factor based thereon, said weighting factor being applied to vote shares prior to determination as to which frame sequence is transmitted.

17. A method for control of an interactive entertainment apparatus, where the apparatus presents to the user a branch structured narrative, and user input determines which path is followed at at least one narrative branch point, characterised in that, a history of user interactions is maintained and determination as to which path is followed at said at least one narrative branch point is made on the basis of two or more preceding and separate user interactions.

18. A method as claimed in claim 17, wherein a history is maintained for a predetermined number n of preceding user interactions, with the most recent n interactions forming said history.

19. A method as claimed in claim 17, wherein user interactions are classified into two or more categories, a history is maintained for each category, and each branch point of the narrative specifies the category on the basis of which path selection is to be made.

20. A method of supplying an interactive narrative entertainment comprising the steps of:

providing a branch structure for the narrative;

making available sequences of image frames for each path of the branch structure;

logging user requests for image frame sequences; and

for each branch point for which one or more requests are made, determining which sequence is sent at least partially on a historical record of user interactions, and at least partially on the basis of the number of requests received.
