Abstract: An annotation suggestion platform may comprise a client and a server, where the client captures a media object and sends the captured object to the server, and the server provides a list of suggested annotations for a user to associate with the captured media object. The user may then select which of the suggested metadata is to be associated or stored with the captured media. In this way, a user may more easily associate metadata with a media object, facilitating the media object's search and retrieval. The server may also provide web page links related to the captured media object. Suggested metadata may be viewed, selected, and associated through a user interface. The user interface may additionally provide space for web pages to be navigated and viewed.

Abstract: Video sharing is described. In an embodiment, mobile video capture devices such as mobile telephones capture video streams of the same event. A video sharing system obtains contextual information about the video streams and uses that to form a video output from the streams, that output being for sharing by other entities. For example, the formed video provides an enhanced viewing experience as compared with an individual one of the input video streams. In embodiments the contextual information may be obtained from content analysis of the video streams, from stored context information and from control information such as device characteristics. In some embodiments the video streams of a live event are received and the output video formed in real time. In examples feedback is provided to video capture devices to suggest that the zoom, viewing position or other characteristics are adjusted or to achieve this automatically.

Abstract: Composite video generation is described. In an embodiment, mobile video capture devices, such as mobile telephones, capture video streams of a common event. A network node receives the video streams and time-synchronizes them. Frames from each of the video streams are then stitched together to form a composite frame, and these are added to a composite video sequence. In embodiments, the composite video sequence is encoded and streamed to a user terminal over a communications network. In embodiments, the common event is a live event and the composite video sequence is generated in real-time. In some embodiments, the stitching of the video streams is performed by geometrically aligning the frames. In some embodiments, three or more mobile video capture devices provide video streams.

Abstract: Methods which use an ID domain to improve searching are described. An embodiment describes an index phase in which an image of a document is converted into the ID domain. This is achieved by dividing the text in the image into elements and mapping each element to an identifier. Similar elements are mapped to the same identifier. Each element in the text is then replaced by the appropriate identifier to create a version of the document in the ID domain. This version may be indexed and searched. Another embodiment describes a query phase in which a query is converted into the ID domain and then used to search an index of identifiers which has been created from collections of documents which have been converted into the ID domain. The conversion of the query may use mappings which were created during the index phase or alternatively may use pre-existing mappings.
