摘要： In a peer-to-peer network of peers which are interconnected for sharing content data, the peers store content files of content data in a file structure comprising a plurality of content folders each content folder containing any number of content files of related content data, and a description file containing both unique identification information and descriptive information in XML format describing the content file or files stored in the same content folder. Requesting peers transmit search query messages which specify search criteria for passage through the network. Peers receiving a search query message compare the search criteria with the descriptive information contained in the description files in each of their plurality of content folders and in the event of there being a matching content folder transmit a hit message including the identification information to identify the matching content folder for passage back through the network to the respective requesting peer.

摘要： A method of data processing. The method comprises applying a filter to an input sample set comprising sample values selected from an input sequence of input sample values, so as to generate a corresponding output sample value having an output sample value position with respect to the input sample set, in which the filter has a maximum output range. The method further comprises deriving a permissible output value range from an input group of two or more input sample values in the input sample set which surround the output sample value position, detecting whether the output of the filter is outside the permissible output value range and, if so, limiting the output of the filter to lie within the permissible output value range.

摘要： An encoding data processing apparatus generates a video material item marked copy by embedding a payload data word into the video material item. The video material item includes plural video frames. A code word generator generates a water mark code word from the payload data word and reads data representing the water mark code word into a shuffle data store. A shuffle processor generates pseudo randomly at least one address within an address space of the shuffle data store for each video frame and reads data representing part or parts of the water mark code word out from the data store at locations identified by the pseudo randomly generated address. A data embedding processor receives the video material item and embeds the data representing the part or parts of the water mark code word read out from the shuffle data store for each frame into a corresponding frame of the video material item.
