摘要:
An encoder encodes data to generate corresponding encoded data. The encoder includes a data processing arrangement for applying one or more encoding processes to the data to generate the encoded data. The data processing arrangement is operable to represent the data at least partially in a set of numerical value symbols, if the data is not already expressed in numerical value symbols. The data processing arrangement is operable to generate intermediate data in which the numerical value symbols are represented by original values and at least one symbol by a modified value with one or more continuum symbols generated by a continuum operator. The one or more continuum symbols modify preceding symbol values to accommodate an extended range of symbols.

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:
There is provided an encoder and decoder for encoding and decoding input data (D1, D2 or D3) to generate corresponding encoded output data (D2 or D3, D5). The encoder includes a data processing arrangement, optionally for analyzing a range of values present in the input data (D1) to determine at least one pre- and/or post-pedestal value, optionally to translate the input data (D1) using the at least one pre- and/or post-pedestal value to generate translated data, and then to apply a form of ODelta coding to the data, optionally translated data, to generate processed data, and to combine the processed data and optionally the at least one pre- and/or post-pedestal value for generating the encoded output data (D2 or D3). The decoder includes a data processing arrangement for processing the encoded data (D2 or D3), optionally to extract therefrom at least one pre- and/or post-pedestal value.

摘要:
A method of encoding source data to generate corresponding encoded data for transmission or storage includes matching one or more portions of the source data to one or more elements in one or more databases, wherein the one or more elements are representative of corresponding one or more data blocks, and recording reference values which relate the one or more portions of the source data to the one or more matched elements; and including the reference values in the encoded data together with the one or more databases and/or information identifying the one or more databases. The methods are implemented in an encoder, a decoder and in a codec. In the codec, the at least one encoder and the at least one decoder share one or more databases referred to by reference values included in the encoded data.

A method of encoding source data to generate corresponding encoding data for transmission or storage is provided, wherein the method includes: (a) matching one or more portions of the source data to one or more elements in one or more databases, wherein the one or more elements are representative of corresponding one or more data blocks, and recording reference values which relate the one or more portions of the source data to the one or more matched elements; and (b) including the reference values in the encoded data together with the one or more databases and/or information identifying the one or more databases. A similar method of decoding encoded data to generate corresponding decoded output data is also provided is also described. The methods are beneficially implemented in an encoder, a decoder and in a codec.
摘要:
An encoder is operable to encode input data to generate corresponding encoded output data. The encoder includes data processing hardware. The encoder compresses content associated with blocks or packets, so that the encoded output data is smaller in size than the input data.

The invention relates to an image processor configured to: receive an image, take area-specific samples (11) of the image information of the area and calculate (12) a reference value (REF) on the basis of the samples; store into a memory (16) or to transmit (17) the reference value (REF) calculated for an area and the area identifier (ALUE) area-specifically; check (13) whether the reference value (REF) obtained as a result of the calculation and the image information (INF) corresponding to it have already been stored in the memory (16) or transmitted (15); and to store into the memory (16) or to transmit (15) the calculated reference value (REF) and the corresponding image information (INF), if the reference value (REF) and the corresponding image information (INF) have not been stored into the memory or transmitted previously.

The invention relates to a pattern recognizer, which, in order to recognize the pattern fast and with lowest possible computing power, comprises a memory (12) for storing area-specific reference values (REF) calculated on the basis of image information of image areas containing parts of the pattern to be recognized, and a processor (14) that is configured to divide (15) a received image into areas, to calculate (16) reference values (REF) area-specifically on the basis of the image information of said areas, to compare (17) the calculated reference values (REF) with the reference values (REF) stored in the memory (12) and to indicate (18) that the pattern is recognized, in case in the received image there is found a part consisting of adjacent areas, where the reference values (REF) of the areas correspond, with sufficient accuracy, to the reference values (REF) stored in the memory (12).
