Variable Bit Rate — WikiV A compression scheme in which each unit of input material can be compressed to different sizes. For MPEG 2 video, for example, this means that “easier” sequences (that is, with no motion) can compress to very small sizes, whereas “hard”… … Audio and video glossary
Bit rate — Bit rates Decimal prefixes (SI) Name Symbol Multiple kilobit per second kbit/s 103 megabit per second Mbit/s 106 gigabit per second Gbit/s 109 … Wikipedia
BIT RATE — T&F In telecommunications and computing, bit rate (sometimes written bitrate, data rate or as a variable R) is the number of bits that are conveyed or processed per unit of time. The bit rate is quantified using the bits per second (bit/s or bps) … Audio and video glossary
Variable bitrate — (VBR) is a term used in telecommunications and computing that relates to the bitrate used in sound or video encoding. As opposed to constant bitrate (CBR), VBR files vary the amount of output data per time segment. VBR allows a higher bitrate… … Wikipedia
Rate–distortion theory — is a major branch of information theory which provides the theoretical foundations for lossy data compression; it addresses the problem of determining the minimal amount of entropy (or information) R that should be communicated over a channel, so … Wikipedia

Data compression — Source coding redirects here. For the term in computer programming, see Source code. In computer science and information theory, data compression, source coding or bit rate reduction is the process of encoding information using fewer bits than… … Wikipedia
List of device bit rates — This is a list of device bit rates, or physical layer information rates, net bit rates, useful bit rates, peak bit rates or digital bandwidth capacity, at which digital interfaces of computer peripheral equipment and network devices can… … Wikipedia
Audio compression (data) — For processes which reduce the amount of time it takes to listen to and understand a recording, see time compressed speech. Audio compression is a form of data compression designed to reduce the size of audio files. Audio compression algorithms… … Wikipedia
Image compression — is the application of Data compression on digital images. In effect, the objective is to reduce redundancy of the image data in order to be able to store or transmit data in an efficient form.Image compression can be lossy or lossless. Lossless… … Wikipedia
S3 Texture Compression — (S3TC) (sometimes also called DXTn or DXTC) is a group of related lossy texture compression algorithms originally developed by Iourcha et al. of S3 Graphics, Ltd. [1] for use in their Savage 3D computer graphics accelerator. The method of… … Wikipedia
