The Basics and Benefits of Image Compression by Scott Heath
Thanks to technological advances and the advent of the internet, image files have become one of the most common file types to be used and shared today. But along with their convenience, image files are often large, making them difficult to store and transmit. ... If you're still skeptical, try downloading image compression software and run some tests on your own image collection. ... Lossy compression works by removing image detail, but not in such a way that it is apparent to the viewer. ... Usually, lossless compression will be most effective on images with less color (such as a small...

Mpeg Encoders by Jennifer Bailey
Movie viewing and editing has never been the same because of MPEG encoders. What exactly is it and how can you use it to make the quality of the movies you are watching better? Read on to satisfy your curiosity. MPEG encoders defined Moving Pictures Experts Group (MPEG) encoders are software... Making movies with MPEG encoders (for advanced users) You can change the performance of your MPEG encoder by simply changing the compression scheme settings on your computer. ... You typically need to adjust the number of I, P and B frames – the more B and P frames you activate, the higher the...

Data and MP3 Compression: Why Do We Compress? by Matthew Bredel
In the last article (Data and MP3 Compression: Understanding "Digital"), I explained what a "digital" signal is. Remember, data can be stored as raw, or "analog" signals (like cassette tapes, VHS, or records) or they may be digitized (converted into a series of 1's and 0's) which we can later... How compression works is that we take the 70MB signal (as we described above) and by using either a mathematical algorithm or map, we can organize the bits in such a way that less bits are required to store the same amount of information (My next articles will cover the details about this a bit more).

Why Do I Need Photo Compression Software? by Scott Heath
Like time in a bottle, our photographs are memories of moments forever captured. In conventional cameras, chemical and mechanical processes captured images on film. To email a picture taken on film to a friend, the film needs to be developed into individual photos, and the photo then has to be... Another way to reduce the amount of memory needed to store images on your computer is to use compression software. ... Compression software works by eliminating repetitive information in a file, thus reducing the size.

DivX and Movie Downloading -- What, How, and Why? by Sergio D'Alesio
Most films that are downloaded at present,are in the DivX Format,and by using this method of compression/decompression, a Movie can typically be compressed to about one tenth of its original size and downloaded without noticeable loss of quality to a users PC. ... When a DivX encoded Movie is played out from its storage media (DVD/CD/Hard Drive),it is decompressed by the DivX software and relayed on to a DivX compatible Media Player such as Windows Media Player for Viewing. ... In practise DivX is used in the form of codec software,(a codec is a compressor/decompressor).

DVD Basic Facts by Ray P

DVD is short of Digital Versatile Disk. A DVD-ROM closely resembles a CD or compact disk. ... MPEG stands for "Motion Picture Experts Group." It stands for the committee that dreamed up the MPEG-2 compression algorithm. ... The encoding process uses lossy compression that removes redundant information. ... This is done on DVD authoring software.

MPEG Encoder for Burning DVDs by Mansi Aggarwal
MPEG, or Moving Picture Experts Group, is a jointly working group comprised of the International Standards Organization and International Electro-Technical Commission (ISO/IEC) to standardize the coding of moving pictures and the associated audio in a digital compressed format. ... However, the process is streamlined where you as the end user are only expected to follow short, simple commands by the software to burn your encoded data. ... And lastly, when in doubt about which MPEG compression algorithm to use to encode your data, “google” it.

Brief Explanation of Digital Signal Processing, Compression, Encryption, and File Translation by O G Popa

Considering the name, Digital Signal Processing, people are lead towards thinking that this procedure deals with digital signals. ... This information is very important, because it helps us to convert our series of integers into a mathematically encrypted structure, by means of a software compression/encryption “key”. ... There are very many compression/encryptions methods available, and very many will be developed into the future.
