| 20080204283 | METHOD AND APPARATUS FOR OPTIMIZATION OF SIGCOMP UDVM PERFORMANCE - A signal compression optimization system between a communication network and wireless user equipment advantageously selects an optimized decompressor when feasible for reduced content processing latency and otherwise selects a virtual machine decompressor, such as a Universal Decompressor Virtual Machine (UDVM) that interprets the received decompression bytecode. Since the UDVM is not optimized for any particular decompression algorithm and suffers by the requisite delays associated with analyzing each statement in the bytecode before execution, being able to avoid use of the UDVM whenever possible enhances user experience in presenting wirelessly received signaling messages or media content. | 08-28-2008 |
| 20080204284 | Data Compression Using a Stream Selector with Edit-In-Place Capability for Compressed Data - A method for encoding an input file into an output file that is compressed so that the number of bits required to represent the output file is less than the number of bits of the input file. The encoding method includes the parsing of the input file into a series of data items, the data items having an order and collectively corresponding to the input file. The encoding method compares the series of data items against a static dictionary having at least mappings between terminal sequence pointers and representations of data items. Each mapping has an associated length, the associated length for a mapping being the length of the data item pointed to by its terminal sequence pointer wherein the terminal sequence pointers are represented by a number of bits that is independent of the particular data items in the input file, the static dictionary being static such that the static dictionary is usable to provide a mapping between a terminal sequence pointer and its corresponding representation of data item independent of mapping of other data items. The encoding method adds to the output file an output file element that is a terminal sequence pointer for data items that map to entries in the static dictionary, each output file including at least one terminal sequence pointer. The encoding method adds to the output file an output file element that is a symbol sequence having one or more symbols for data items that are to be represented directly in the output file, and creates an element mapping for the output file to indicate, for each output file element, whether the output file element corresponds to a terminal sequence pointer or a symbol sequence. | 08-28-2008 |

| 20090284400 | Method and System for Reducing Required Storage During Decompression of a Compressed File - A method and system for decompressing a compressed file is disclosed in this invention, the method comprising: reading a compressed data block from the compressed file; decompressing the compressed data block; outputting the decompressed data for storage into a decompressed file; deleting the compressed data block that was decompressed from the compressed file.

Thus, this invention is easy to be integrated into existing compression/decompression tools. | 11-19-2009 |
| 20090322571 | COMPRESSION SCHEME FOR INTERVAL DATA - A method of data compression for use in a data communication's system for an electrical utility or the like to affect the most efficient transfer of data. The data is first formed into a forming a block (B). A parameter (M) is selected from among a group of parameters. Each data value in the block is divided by the selected parameter to produce, for each data value, a quotient (q=└n/M┘) and a remainder (r=n−qM). The quotient of each data value is encoded using unary coding in which the value for the quotient is encoded by transmitting an appropriate number of zeroes followed by a one. The remainder of each data value is encoded using binary encoding, and the resultant encoded block of data is then transmitted. The data values comprising the block of data are positive integer values and the encoding employs a Golomb-Rice code defined by a positive integer parameter. | 12-31-2009 |
| 20100079313 | METHOD AND APPARATUS FOR COMPRESSING AND DECOMPRESSING DATA - The described embodiments include a system for performing data compression. The system includes a compression mechanism with N channels, and an internal decompression mechanism in the compression mechanism that accepts N channels of fixed-length packets. The compression mechanism is configured to receive an input bit stream that includes a set of data words. In response to receiving a request from the internal decompression mechanism identifying at least one of the channels for which a fixed-length packet is to be appended to the output stream, the system fills a fixed-length packet for the identified channel with compressed data words; appends the fixed-length packet to the output stream; and forwards a copy of the fixed-length packet to the internal decompression mechanism. The internal decompression mechanism decompresses fixed-length packets for each of the channels to determine a next fixed-length packet to be appended to the output stream. | 04-01-2010 |
