摘要： The invention relates to a method of processing data, the method comprising steps of enabling to (210) encrypt first data for a first source, and encrypt second data for a second source, (220) provide the encrypted first and second data to a server that is precluded from decrypting the encrypted first and second data, and from revealing identities of the first and second sources to each other, (230) perform a computation on the encrypted first and second data to obtain a similarity value between the first and second data so that the first and second data is anonymous to the second and first sources respectively, the similarity value. providing an indication of a similarity between the first and second data. The method may further comprise a step (240) of using the similarity value to obtain a recommendation of a content item for the first or second source. The first or second data may comprises a user profile or user ratings of content items. One of the applications of the method may be in collaborative filtering systems.

摘要： A broadcast system for broadcasting data streams includes a hierarchical network of data distributors starting from one central distributor (110) through at least one layer of intermediate distributors (120, 130, 140) to a plurality of broadcast receivers (150). Data streams are broadcast through downstream channels (160) of the network to the plurality of broadcast receivers. At least one distributor hierarchically below the central distributor is operative to insert broadcast data in at least one up-stream channel (170) of the network towards the central distributor. The central distributor is arranged to re-distribute broadcast data received via at least one up-stream channel through at least one downstream channel of the network.

摘要： In a broadcast system 100 a broadcasting device broadcasts titles using a near-video-on-demand broadcasting protocol. Data blocks of a title are broadcast via c parallel equal capacity channels of the broadcast system. The broadcast channels 160 including time-sequentially interleaved sub-channel(s). The title is divided in a plurality of consecutive data block sequences. Each block sequence is assigned to one respective sub-channel. The broadcasting device repeatedly broadcasts each block sequence in the assigned sub-channel. The broadcast receiver 150 has a capacity to simultaneously receive all sub-channels of a plurality r (1i, the receiver terminates reception of the sub-channel in channel i and starts reception of at least one sub-channel of channel r+i.

摘要： A method for generating a recommendation is provided. The method includes the steps of: receiving at least one of a negative and positive example from one or more other users; and determining a recommendation for a user based on at least one of the negative and positive examples. The method can further include the step of generating a user profile for the user based on previous behavior of the user, in which case the determining step can include determining the recommendation based on the negative example and the user profile. The determining step can also include the step of determining the recommendation based on both of the negative and positive examples.

摘要： The invention relates to a data processing device (100) enabling a user to input characters, the device comprising a touch-sensitive member (200) arranged to function as a virtual keyboard, said member including at least one touch sensor (160) for detecting touched zones on said member. The device further comprises key allocation means (110) for allocating at least two reference keys (220) of the virtual keyboard in response to said detection of the touched zones. The device comprises at least one pressure sensor (170) for sensing a finger (250) causing a force on the touch-sensitive member higher than other fingers when more than one finger touches said member. A recognition of a key stroke may be realized. The reference keys may be reallocated upon a user's request or detection of a predetermined condition. The invention also relates to a method of enabling a user to input characters.
