摘要： Protecting usage of key store content at a given user device of an end user includes receiving the key store content at the given user device. The key store content includes key materials encrypted using encryption credentials compatible with the given user device. The key store content is in a format compatible with the given user device. The encrypted key materials of the key store content are imported to a protected key store of the given user device, wherein all the key materials of the key store content are imported at one go. The key materials are stored at the protected key store in the encrypted form, and are non-exportable from the key store. Internally within the protected key store, one or more key store integrated services of the given user device are allowed to access the non-exportable key materials for use, via key references only.

摘要： A system for creating one or more group networks between network devices belonging to one or more local networks. Group network devices, dynamically installed at the local networks, are employed to discover network devices connected to their corresponding local networks. Information indicative of a plurality of network devices discovered by the group network devices or selected by a user from amongst the discovered network devices for creation of a group network is received. The plurality of network devices are assigned to the group network, and defined as members of the group network. The group network devices are employed to automatically perform network configurations for the plurality of network devices, regardless of whether the members of the group network are connected to a same physical local network or to different geographically-separated physical local networks. The group network so created enables the members of the group network to communicate and interoperate with each other in their native protocols. The given group network supports different types of transmission paths and/or different transmission protocols defined by the transmission paths.

摘要： An encoder for encoding input data to generate corresponding encoded data is provided. The encoder (10) is operable to process a sequence of elements in the input data from a first element thereof to a last element thereof. The elements have corresponding symbols. The encoder is operable to compute probabilities of symbols present in the sequence, wherein the probabilities of the symbols are computed while disregarding those elements of the sequence that have already been encoded into the encoded data. Moreover, the probabilities of the symbols are adaptively changed as the sequence of elements is progressively encoded into the encoded data. Furthermore, information describing the probabilities is delivered; optionally, the probabilities of the symbols are accompanied with additional information indicating how the probabilities are adaptively changing. There is also provided a decoder for performing an inverse of encoding performed by the encoder.

摘要： An encoder for encoding data to generate corresponding encoded data including information indicative of a frequency, probability or range of one or more symbols to be represented in the encoded data. The encoder can include in the encoded data additional information indicative of whether information indicative of a frequency, probability or range for at least one symbol amongst the one or more symbols is in the encoded data. The encoder can include in the encoded data the additional information of whether information indicative of a frequency, probability or range for at least one symbol amongst the one or more symbols in the encoded data expressed as single availability bit information. The encoder can represent inclusion of information indicative of the frequency, probability or range information by use of a single availability bit value “7”, and non-inclusion of information indicative of the frequency, probability or range information by use of a single availability bit value “0”.

摘要： A data communication system includes a centralized server arrangement coupled via a communication network arrangement to a plurality of client devices. The centralized server arrangement and the plurality of client devices exchange data. The system allocates the data into a primary type of data and at least a secondary type of data. The primary data is communicated substantially immediately within the system, and at least the secondary data is communicated in the system in association with corresponding acknowledgements (ACK) in response to receipt of the second type of data at one or more of the client devices. At least one of the one or more client devices is optionally a wireless-enabled mobile communication device or a wirelessly-connected personal computer (PC).

摘要： An encoder is provided for encoding input data (D1) to generate corresponding encoded output data (D2). The encoder includes a data processing arrangement for generating a run-length encoded (RLE) representation of the input data (D1). Moreover, the encoder is operable to split the run-length encoded (RLE) representation into a plurality of parts (A, B), wherein at least one part is associated with original symbols and at least another part is associated with counters representative of occurrence of the original symbols. Furthermore, the encoder is operable to encode the plurality of parts (A, B) separately to generate the encoded output data (D2). There is also provided a corresponding decoder for decoding the encoded data (D2) to generate corresponding decoded output data (D3). Additionally, there is provided a coder including the aforesaid encoder and decoder.

摘要： An encoder includes data processing hardware which is operable: to divide input data into a plurality of blocks or packets; to apply a plurality of transformations to content of the blocks or packets to generate corresponding transformed data; to check a quality of representation of the transformed data prior to application of the transformations to determine whether or not the quality of representation of the transformed data satisfies one or more quality criteria; if the quality of representation of the transformed data does not satisfy the one or more quality criteria, to sub-divide and/or to combine the one or more blocks or packets further and repeating the transformation step; and if the quality of representation of the transformed data satisfies the one or more quality criteria, to output the transformed data to provide encoded output data representative of the input data to be encoded.
