摘要： Data may be efficiently analyzed and compressed as part of a data compression service. A data compression request may be received from a client indicating data to be compressed. An analysis of the data or metadata associated with the data may be performed. In at least some embodiments, this analysis may be a rules-based analysis. Some embodiments may employ one or more machine learning techniques to historical compression data to update the rules-based analysis. One or more compression techniques may be selected out of a plurality of compression techniques to be applied to the data. Data compression candidates may then be generated according to the selected compression techniques. In some embodiments, a compression service restriction may be enforced. One of the data compression candidates may be selected and sent in a response.

摘要： Exemplary methods, computer systems, and computer program products for processing a previously compressed data stream in a computer environment are provided. In one embodiment, the computer environment is configured for separating a previously compressed data stream into an input data block including a header input block having a previously compressed header. Sequences of bits are included with the input data block. Compression scheme information is derived from the previously compressed header. The input data block is accessed and recompressed following the header input block in the previously compressed data stream one at a time using block-image synchronization information. Access to the block-image synchronization information is initialized by the compression scheme information to generate an output data block. The block-image synchronization information is used to provide decompression information to facilitate decompression of the results of the output data block.

摘要： Embodiments of the present invention relate to the database field, and in particular, to a data transmission method and apparatus, so as to reduce overheads for data transmission between nodes in a distributed database and lighten network load. In the embodiments of the present invention, a DN determines one to-be-transmitted column that has a distribution rule, and the distribution rule of parameters in the to-be-transmitted column; the DN determines, according to a data type of the parameters of the to-be-transmitted column and the distribution rule of the parameters in the to-be-transmitted column, a compression algorithm corresponding to the to-be-transmitted column; the DN compresses the to-be-transmitted column by using the compression algorithm; and the DN sends a compressed to-be-transmitted column to a target node. In this way, the overheads for the data transmission between the nodes are reduced, and the network load is lightened.

摘要： Methods, devices and systems enhance compression and decompression of data values when they comprise a plurality of semantically meaningful data fields. According to a first inventive concept of the present invention disclosure, compression is not applied to each data value as a whole, but instead to at least one of the semantically meaningful data fields of each data value, and in isolation from the other ones. A second inventive concept organizes the data fields that share the same semantic meaning together to accelerate compression and decompression as multiple compressors and decompressors can be used in parallel. A third inventive concept is a system where methods and devices are tailored to perform compression and decompression of the semantically meaningful data fields of floating-point numbers after first partitioning further at least one of said data fields into two or a plurality of sub-fields to increase the degree of value locality and improve compressibility of floating-point values.

摘要： Video coding systems or apparatus utilizing context-based adaptive binary arithmetic coding (CABAC) during encoding and / or decoding, are configured according to the invention with an enhanced binarization of non-zero Delta-QP (dQP). During binarization the value of dQP and the sign are separately encoded using unary coding and then combined into a binary string which also contains the dQP non-zero flag. This invention capitalizes on the statistical symmetry of positive and negative values of dQP and results in saving bits and thus a higher coding efficiency.

摘要： In 3D mesh coding, the geometry data is compressed by spatial tree based approaches. Bitstreams that result from the traversal of a tree structure of spatial tree based approaches for encoding 3D mesh models have systematically special redundancies, which is exploited for further improving the mesh model compression. A method for encoding a bitstream comprises steps of defining at least a first and a second symbol group of binary symbols, with S1 being a subset of S2, determining within the bitstream first portions, second portions and third portions, wherein first portions have Th1 or more consecutive S1 symbols and second portions have Th2 or more consecutive S2 symbols, encoding the bitstream, wherein first portions, second portions and third portions are encoded using different codes, and encoding values indicating the boundary positions between the first, second and third portions in the bitstream.
