How does compression work?

Data compression is a well established technology which can reduce the size of a file by a significant margin without losing any of the original data. The compression mechanism looks for repeated patterns in the source file and removes the unnecessary data from the file. IISxpress uses the ZLIB and GZIP 'deflate' algorithm as specified in the HTTP/1.0 and HTTP/1.1 standards for maximum compatibility and performance.

How is data compression done in UMTS?

UMTS and 3G FAQ page
Video and music compression will be done in application level. 3G phone (and network application servers) will have programs (or you will be downloading them) that records and displays video or music. Those programs have build-in data compression features. Good examples are MP3 and other music programs. MP3 codec includes data compression and most current music player understands it. For image and video there are several standards including JPEG, MPEG-4, H.263, Microsoft media player etc. See similar questions...

What is data compression?

NCIA Support
Once error correction has been established, the next step up is data compression. You must have error control before you ever even attempt to compress the data. What data compression does is exactly what it says. It takes the data given and compresses it, just like any archive compression tool, and then sends it over the phone lines. Take a large text file and run WinZip on it. You will note the size of the file goes from maybe 500k to 35k. See similar questions...

How much compression can I expect from my data?

That depends on the type of data you are backing up. The amount of compression varies from 90% compression for text based files to 0% compression for compressed image type files. See similar questions...

What is data compression and how is it beneficial?

SkyeWired Mobile Field Service Management
Wireless networks charge their customers based on the amount of data transferred. Data compression compresses the data into a smaller amount, resulting in lower wireless network use charges. Also the double stage data compression on SkyeWired makes the data unreadable to the average user. See similar questions...

I had a file rejected because of "noise" or "compression artifacting". What does this mean?

Frequently Asked Questions | iStockphoto.com
A little bit about compression: The JPEG file format uses a "lossy" compression method. In order to make the file smaller, information is thrown away, or lost. The "quality" setting that most image editing programs and digital cameras have when saving JPEGs determines how much information is lost. See similar questions...

gt;15. Whats up with your high/low speed remote compression adjuster. How does it work?

Faq's - Avalanche Downhill Racing
The remote hi/low speed adjuster has a low speed needle and a high speed blow off valve and as you adjust the screw tighter it increases the low speed compression and also increases the preload force on the blow off valve thus giving the shock more high speed compression. If the shock experiences a large high speed hit it will still blow off to prevent harshness and prevent the shock from hydraulic lock (keeps the shock from blowing up). See similar questions...

How can I organize data compression on the vessel in practice?

Marinfo
Data compression can be organized in two ways: by delivering software for the vessel, or setting-up existing program means of Inmarsat-C terminal. The first variant makes operator's work entirely automatic, but requires separate computer on the vessel. The second variant doesn't suppose any additional means, but makes ship operator's work just a little bit more complicated. Also, we offer for today new progressive compressor for miniM, A/B/M/Iridium terminals. See similar questions...

What should I know about compression?

TuneCore: FAQ
Music files primarily come in two varieties: "compressed" and "uncompressed." An uncompressed music file is the music stored as faithfully as the computer can hold it, just like the music on normal audio CDs. These are large files and hold every scrap of data the computer needs to reproduce the music as closely as it can to the original recording. These files are often named with .WAV or .AIFF extensions. See similar questions...

What compression formats does Squeezebox use?

Slim Devices : Product Info : FAQ
Squeezebox supports MPEG 1/2, layers 2/3, for both VBR and fixed data rates up to 320Kbps (the maximum for MP3). Additionally, Squeezebox can play FLAC and Apple lossless encoded audio as well as AIFF and WAV uncompressed audio. This means that the original data from the CD is being played digitally, without any compression or loss of sound quality. The SlimServer software can automatically convert many formats on the fly for playback, including WMA, AAC and Ogg Vorbis. See similar questions...

What video compression type does the program use to compress a time-lapse avi?

Willing Webcam FAQ - Frequently Asked Questions
What does the "compression" value under the time lapse mean. There is another compression option under the "Options" icon where I can select my compression codec and select a level of compression but this doesn't change the compression value in the time-lapse section. The compression option under the 'Options' icon works with streaming avis. The 'compression' value under time lapse works with time-lapse ones. See similar questions...
