Captioning system
First Claim
1. A captioning system for providing captions for a presentation to a user, the captioning system comprising:
- a caption store operable to store one or more sets of captions each set being associated with one or more presentations and each set comprising a plurality of captions for playout at different timings during the associated presentation; and
a user device having;
i) a memory operable to receive and store at least one set of captions for a presentation to be made to an associated user, from said caption store;
ii) a receiver operable to receive synchronisation information defining the timing during the presentation at which each caption in the received set of captions is to be output to the user;
iii) a caption output circuit operable to output to the associated user, the captions in the received set of captions; and
iv) a timing controller responsive to said received synchronisation information and operable to control said caption output circuit so that said captions are output to said user at the timings defined by said synchronisation information.

Abstract
A captioning system is provided for providing captions for audio and/or video presentations. The captioning system can be used to provide text captions or audio descriptions of a video presentation. A user device is provided for the captioning system having a receiver operable to receive the captions together with synchronisation information and a caption output circuit which is operable to output the captions at the appropriate timings defined by the synchronisation information. The user device is preferably a portable hand-held device such as a mobile telephone, PDA or the like.

35. A method of manufacturing a computer readable medium storing caption data and synchronisation data for use in a captioning system, the method comprising:
-
providing a computer readable medium;
providing a set of captions that is associated with a presentation which comprises a plurality of captions for playout at different timings during the associated presentation;
providing synchronisation information defining the timing during the presentation at which each caption in the set of captions is to be output to a user;
receiving a computer readable medium;
recording computer readable data defining said set of captions and said synchronisation information on said computer readable medium; and
outputting the computer readable medium having the recorded caption and synchronisation data thereon.

37. A method of providing captions for presentation to a user, the method comprising:
-
storing, at a caption store, one or more sets of captions each being associated with one or more presentations and each comprising a plurality of captions for playout at different timings during the associated presentation; and
at a user device;
receiving and storing at least one set of captions for a presentation to be made to an associated user from said caption store;
receiving synchronisation information defining the timing during the presentation at which each caption in the received set of captions is to be output to the user;
outputting the captions in the received set of captions to the associated user; and
in response to the received synchronisation information controlling the outputting step so that said captions are output to the user at the timings defined by the synchronisation information.
