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.

There is described a number of encoders for encoding a data signal within an audio signal. In some of the encoders, the audio signal is separated into a tonal part and a residual part, and the data signal is shaped based on the residual part. In other encoders, the data signal is separated into a tonal part and a residual part, and the data signal is combined with the audio signal independence upon the residual part. In other encoders, the rate at which the data is encoded within the audio signal is varied in dependence upon the audio signal. There are also described various decoders associated with the described encoders.

A method of combining projected images with a three dimensional set. In the present invention, a three dimensional set of any desired scale is provided. A second set is then built for use by live actors and other desired images to be incorporated into the three dimensional scene. Props are disposed on the second set and corresponds to the three dimensional scenes. These second set props are blacked out so that when photographed they are rendered invisible. A beam splitter is provided in front of the three dimensional set and a monitor is positioned to reflect a video image from the second set on to the beam splitter. The actors and props on the second set are then positioned to achieve the desired scale. For example, the projected image of the actor may be life size, smaller than life size or larger than life size. The actor is then filmed in real time interacting with the blacked out second set props and the image is recorded. The recorded image is then played back on the monitor reflected on to the beam splitter to give the illusion that the recorded image is interacting with the props in a three dimensional set. The live image may be transmitted directly to the monitor for projection on to the beam splitter without first recording it, if desired.
摘要:
A system for gathering and analyzing data on individuals, comprising a processor connected to a network; a database server connected to the processor; a user database connected to the processor; and a user interface operable to interact with the processor and the user database; wherein the processor is operable to obtain information associated with a reference individual from sources connected to the network and store the information in the database server, wherein one source includes a social network database and the information includes related individual information; receive a search request from the user interface, search the information stored in the database server in response to the search request and generate a search result based thereon; determine a relevance value for the related individual information; cause the user interface to display the search result and relevance value; and store the search result in the user database as permitted by law.
摘要:
A data hiding system is described for hiding data within an audio signal. The system can be used for watermarking, data communications, audience surveying etc. The system hides data in an audio signal by adding artificial echoes whose polarity varies with the data to be hidden. In one embodiment, each data value is represented by a positive and a negative echo having different delays. A receiver can then remove the effects of natural echoes and/or periodicities in the audio signal by differencing measurements obtained at the different delays.

An electronic synapse device comprising a substrate formed from semiconductor material; a first input for receiving a weighting signal; a second input for receiving a signal from a pre-synaptic neuron device; an insulating layer provided between the first and second inputs and the semiconductor material; and an output, the second input being located between the first input and the output. Upon application of the weighting signal to the first input a quantity of charge accumulates in said substrate in the region said first input. Subsequently, upon application of the pre-synaptic signal to the second input, the charge is transferred to a region of the substrate that is substantially in register with the second input whereupon the charge causes an output signal to be generated at the output.

A console for a participant in a network-based auction system. A first section of the console includes information regarding an item on which bidding is currently taking place and a visual representation of the item on which bidding is currently taking place. A second section of the console includes information regarding an item in the auction and a visual representation of the item. The console includes an input for causing the second section of the console to display a different item in the auction and display a set of recent bids placed for the item currently being auctioned. According to an embodiment, the second section of the console has display of a plurality of photos of the item. Various other interfaces and methods and systems for managing a network-based auctions for vehicles are also described.
摘要:
A security tag comprising at least one overt data carrier (10), and at least one covert data carrier (25), the covert data carrier comprising a ring (25) that is formed around the overt data carrier (10). The covert data carrier (25) is invisible to the unaided eye when lit with visible light, but visible when illuminated with other light, for example UV light.
