A method, device, and system for data compression and decompression are provided. The method for data compression comprises, converting data to be transmitted within each period, from the time domain to the frequency domain, wherein, a default time length is set as a period; identifying weak power frequencies in the frequency domain data according to a set identification rule; weighting data transmitted on the identified weak power frequencies to obtain corresponding weighting information; converting other data converted to the frequency domain and the weighted data back to time domain; compressing the data converted back to the time domain; and transmitting, the compressed data along the weighting information.

A framework for security information and event management (SIEM), the framework includes a first data store; a data router; one or more parsing mechanisms; one or more correlation machines; and one or more workflow engines, wherein said framework performs SIEM on behalf of multiple subscribers to said framework.

Methods, devices, and computer programs are provided for character conversion. An original file is compressed, for instance, by a source or target device, to obtain a compressed file. Then, characters in the compressed file are converted from a source code page to a target code page to obtain a converted compressed file. The converted, compressed file may, where applicable, be sent to a target device. Also, the target device may decompress the converted compressed file to obtain a file in the target code page.

Systems, apparatus and methods are provided for compressing data. A method may comprise receiving an input data block to be compressed, determining numbers of occurrences for distinct symbols in the input data block, generating reduced numbers of occurrences for the distinct symbols based on the numbers of occurrences for the distinct symbols and encoding the input data block using the reduced numbers of occurrences as probability distribution of the distinct symbols in the input data block.

An endpoint element of a distributed antenna system includes processing circuitry configured for processing a plurality of digital signals for conditioning the signals and compression circuitry configured for compressing at least one of the digital signals according to a compression scheme to yield at least one compressed digital signal and compression settings. The digital signals are combined into a single digital stream and combined and time division multiplexed onto a serial data link with the compression settings. The digital signals are also transmitted with compression settings to another endpoint element over the serial data link.

A transmitting device for communicating via a multimedia communication link includes a compression circuitry that receives blanking period data corresponding to blanking states of video blanking periods. The compression circuitry compresses the blanking period data into compressed blanking period data. The transmitting device also includes an interface that transmits signals corresponding to the compressed blanking period data via one or more multimedia channels of the multimedia communication link.

Methods, systems, and apparatuses (including, but not limited to, User Equipment (UE) and Base Stations) for a UE to control a packet header compression function in a communication system are described. In one method, if a predetermined condition is satisfied while the packet header compression function is enabled, the UE transmits a request for disabling the packet header compression function to a Base Station (BS), and, if a response is received from the BS, the UE disables the packet header compression function.

A system encodes/compresses at least some portion of website data and transmits the encoded website data to a remote user. A storage device stores original website data representing an original webpage. Retrieval logic retrieves the original website data from the storage device. The retrieval may be responsive to a request from an electronic user device. A parser parses the original website data to detect and tag at least one type of website code within the website data. An encoder encodes the tagged website data and produces encoded website data representing the original website data. A transmitter transmits the encoded website data to the electronic user device. The electronic user device has previously been provided a decoder from the system to decode the encoded website data to recover the original website data. This allows the electronic user device to display the website on the electronic user device.
