| | Data Compression - Encyclopedia.WorldSearch |
 | | In computer science, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than a more obvious representation would use, thanks to specific encoding schemes. | | | One very simple means of compression, for example, is run-length encoding, wherein large runs of consecutive identical data values are replaced by a simple code with the data value and length of the run. | | | It is often used to better use disk space on office computers, or better use the connection bandwidth in a computer network. |

| | Compression of Multimedia Information |
| | Optimal compression of artificial MMD are algorithms of their creation. | | | On the other hand, blocks/streams of data of any type.ABZ can be compressed with "losses" (probably, even improving contents from the point of view of the Receiver) by the algorithm specially designed for the data of this type.ABZ (for example, DocumentPress by Igor Pavlov[22], optimization of tables in headers of EXE-files). | | | Computer synthesized MMD (SMMD) also exist, but their total amount is smaller, and they should be better considered as databases: their artificiality is practically always easily seen even by men, and algorithms of their detection are not more complex than algorithms of synthesis of "hand-made" MMD. |

| | Compression |
| | Multimedia designers use compression software to shrink the size of files for easy electronic transmission or simply to conserve disk space. | | | There are many ways of grouping compression algorithms, including: basic/advanced, lossless/lossy, and based on input data. | | | Compression techniques (both lossy and lossless) play a very important role in enabling effective multimedia design, development, and distribution. |

| | Multimedia Data Compression Based on Pattern Matching |
| | We shall propose such a scheme that works for all media by extending lossless Lempel-Ziv to a lossy scheme based on approximate pattern matching. | | | Experimental results for Pattern Matching Image Compression (PMIC) showed great potential for such a scheme. | | | Since most media are represented in a digital form, it is natural to apply a technique that was proved successful for inherently digital media such as text, namely Lempel-Ziv type schemes. |

| | Compression and reliability are opposite functions that are core concepts in the transmission and storage of multimedia objects. | | | Compression is done at the risk of making data more prone to undetected errors during transmission or storage. | | | Lossless compression methods include statistical coding (e.g., Huffman, Shannon-Fano, facsimile, arithmetic, MNP5/7) and dictionary coding (e.g., LZ77, LZ78, LZW). |
