(File size) Resampling, reducing a file size for streaming or sharing over the internet or intranet. Usually a lossy process, causing some loss of audio quality. REAL Media, MPEG, MJPEG, Microsoft wmv/wma are all examples of compressed media. Use Apple's Compressor to compress media. Any video that is not uncompressed, is compressed. HDV uses the MPEG compression format of 4:2:0, while NTSC DV uses 4:1:1.
Audio compression (not to be mistaken with data compression) is the process in which the dynamic range is reduced by making the loud parts quieter and the quiet parts louder.
To condense electronic files for ease of transfer and storage.
For Level 4 detailed holdings statements, to condense one or more data elements through consolidation within one or more levels of data to express the same information with fewer characters. It can only be done when there is no gap in the level or levels to be compressed.
To make a file smaller by applying a compression algorithm, usually for the purpose of conserving space or speeding up file transfers.
make more compact by or as if by pressing; "compress the data"
To make a file smaller by removing repeated or unnecessary information and by employing one of a number of algorithms which summarize patterns in the data being compressed.
To reduce a file's size for more efficient storage of information.
The act of pressing together or to force into a smaller space.
To compact data, such as video files, to save space. Compressing a file often removes redundant pieces of data that are restored when the file is decompressed. More agressive compression schemes can result in partial loss of data in favor of a small file size.
To compact a file or group of files so that they occupy less disk space. See also decompress.
This is a compact way to store files containing text, data, or images. Compressed Windows files are known as ZIP files. Compacted Macintosh files are known as SIT, SEA, or HQX files. Special software is necessary to uncompress these files«Unzip for Windows, and Stuffit Expander for Macintosh.
Shrink file size using a format not usually employed by a specific file type.
computer data can usually be compressed to take less space. Compression software is often used before adding an attachment to an email. Examples are WinZip (Windows) and StuffIt (Macintosh).
This is a digital picture manipulator effect where the picture is made proportionally smaller. Pictures are analyzed looking for redundancy and repetition and unnecessary data is discarded. The technique was primarily developed for digital transmission but has been adopted as a means of handling digital video in computers and reducing the storage demands for digital VTRs. Compression can be at either a set rate or a variable rate. Also known as Bit Rate Reduction (BRR).
compress compress or expand files
(1) To compact data to save space. (2) Common compression function on the Internet. Depending on the distribution of data in a file, compression may reduce its size by 25% to 70%. COMPRESS files are often, but not always, noted with the file extension .Z. Data archive and compression processes can be combined to form files like filename.tar.z (see TAR below). If you download a file with a file type showing that it is compressed, you will need a program to expand it before you can use it. Search the net for files starting with 'comp' (as in COMP430D.EXE) to find programs that can expand .Z-files.
The process of making a file smaller so that it will save disk space and transfer faster over a network. The most common compression utilities are PKZIP for IBM PC or compatible computers (.zip files) and Compact Pro (.cpt files) or Stuffit (.sit files) for Macintosh computers.
Reducing a file to a significantly smaller size without altering the substantive information by eliminating the redundant data.
To reduce, using a variety of computer algorithms and other techniques, the amount of data required to accurately represent a video image or segment, thereby reducing the amount of space required to store it. Most types of compression, such as JPEG, cause some data to be lost. Compare with decompress.
Reducing the size, and therefore the storage requirements, of a data file, by applying a compaction algorithm to remove redundancy in the data.
(verb) To press together; To make more compact by or as if by pressing.
To make data take up less space. Archiving programs do this, which means that files will take less time to transfer with modems. Many modems now have the ability to automatically compress the information they send and receive.
to condense one or more data elements through consolidation within one or more levels of data to express the same information with fewer characters. Data elements may be compressed only if there is not a gap in the level or levels to be compressed.
Store data in such a way that the file size is reduced.
To reduce the size of a digital file for the purpose of speedier file transfer and archiving.
The act of discarding redundant or semi-redundant information from a file, thereby making it smaller.
A program that compacts a file so it fits into a smaller space. This term can also refer to the technique of reducing the amount of space a file takes up.
Converting audio and video data into a compact form for storage or transmission.
Data files available for download from the Internet are typically compressed in order to save server space and reduce transfer times. Typical file extensions for compressed files include zip (DOS/Windows) and tar (UNIX).
Generically, to make a file smaller by removing redundant information. Specifically, the Unix compress program that does just that. Files compressed with the Unix compress command end with a .Z suffix (always a capital Z). Compressed files may be expanded with the Unix command uncompress.
