  | [New 2008] | 
  MP3Players, USB Flash Drives.. | 
   | 
   | 
 
 
   | 
  It contains those file formats: AAC,
  AC3, AMR, GIF, JAR, JPG [EXIF], MP3, MP4, MOV [MotionJPEG], MPG, PDF, PNG,
  SIS, SWF | 
 
 
   | 
  All those files have a compressed
  nature and won't compress well unless special lossless recompression is
  applied. | 
 
 
   | 
  So this test set indicates an
  archiver's skill to serve as lossless backup solution for data from mobile
  devices. | 
 
 
   | 
  Backing up data from mobile devices
  has become more important than personal computer data backup, because not all |

  devices are safe, can be stolen or

   | 
  since 2007 it also includes
  precompressed files like .wmv, .wma (DRM protected), .ogg, .mp4, .avi(MPEG4),
  j2k, .pspimage, |

  .chm, .exe (UPX-compressed), .flv,

  .tif, .tga, .gif (and | 
 
 
   | 
  .gif animations), c4d (3D files from
  CineBench 9.5), .dic (PAQ8 dictionaries).. Some hints: Some raster images
  included here | 
 
 
   | 
  contain identical data: a bitmap was
  stored in compressed .tif, .pcx, .tga.. format. Microsoft's .mht (Web
  Archive) format contains | 
 
 
   | 
  dozens of JPEGs, but they are MIME
  encoded in every .mht file. This testset also contains some visual style
  files (such as | 
 
 
   | 
  WindowBlinds format), but those
  images are inside of renamed .zip archives. This testset has the highest
  difficulty level !!! |

  | What
  the hell is the sense of compressor benchmarks? | 
   | 
   | 
 
 
   | 
   | 
   | 
   | 
 
 
  | Testing compression programs has a long history with some
  very famous persons having only one idea in mind: To find the best
  compression program currently | 
 
 
  | available.
  Back in 1985 the first compressor was born: SQPC file squeezer. And this
  actually evolved a whole compressor population until now. Every
  programmer  | 
 
 
  | claims
  his or her program to be the best around - but how do end users distinguish
  between the good and the bad compressors? The answer should be:  | 
 
 
  | Reading
  such charts. But this is not the case for most of the world's end users. They
  believe in commercials and buy the first one they notice…  | 
 
 
  | But
  when buying a new car every man compares the models around… | 
   | 
 
 
  | It is very very interesting in my opinion that some
  compressors released this year do not compress better than those released
  decades ago,  | 
 
 
  | and
  on the other hand - it is interesting that a few compressors released some
  years ago could compress nearly as well as those released today… | 
 
 
  | By running a compression challenge we can activate perhaps
  developing improvements or at least could we let know some compression
  program writers, | 
 
 
  |  that actually the old compression codecs are
  outdated and should be retired. | 
   | 
 
 
  | It
  is rumored, that every couple of years, when the sun shines some beautiful
  morning, a genius mind creates a new compression algorithm or improves an
  existing… | 
 
 
   | 
   | 
   | 
   | 
 
 
   | 
   | 
   | 
   | 
 
 
  | Why this
  test? | 
   | 
   | 
   | 
 
 
   | 
   | 
   | 
   | 
 
 
  | There
  are a few benchmarks out there and the testers already did and still do
  brilliant work in testing archivers and publishing results.  | 
 
 
  | But
  those results indicate compression capabilities of small & few files
  only. This Squeeze Chart was designed to show the ability of compressors  | 
 
 
  | in
  handling much and large files thus reflecting strength of solid archiving. | 
   | 
 
 
   | 
   | 
   | 
   | 
 
 
  | Why
  is one testset not enough? | 
   | 
   | 
 
 
   | 
   | 
   | 
   | 
 
 
  | Since
  the beginning of Personal Computing in the 80's mankind has discovered many
  fields on which computers can aid and serve. | 
 
 
  |  So nowadays we use computers for text
  processing, presentations, profit calculations, messaging, gaming, seeking
  information, reading books,  | 
 
 
  | listening
  to music, image editing and archiving … | 
   | 
   | 
 
 
  | And
  all this different usage fields have caused different file formats for
  storing data. | 
 
 
  | So
  a file compressor has to understand these different file formats. Mainly,
  there are four elements of which most files consists (in plain or melted
  form): | 
 
 
  |  executables, texts, bitmaps and wavetables.
  Each element needs to be recognized by archiver and requires a specific
  algorithm to be compressed with. | 
 
 
   | 
   | 
   | 
   | 
 
 
  | Can
  compression still be improved? | 
   | 
   | 
 
 
   | 
   | 
   | 
   | 
 
 
  | Improvements
  mean to work out different algorithms for the 4 elements or to modify
  (preprocess) those elements before compression takes place.  | 
 
 
  | The
  LZ-based algorithms are fast, the PPM-based algorithms are slow but do well
  on text, the Arithmetic algorithms are the slowest but superior on binary
  data. | 
 
 
  |  The best way is a hybrid algorithm that has
  the speed of LZ, text sorting power of PPM and the context comparing
  precision of Arithmetic algorithms. | 
 
 
  |  Actually the first step was done with LZMA
  algorithm of Igor Pavlov's 7-Zip that consists of LZ-based speed and
  Arithmetics strength.. | 
 
 
  | And
  there are only a few compressors that can withstand this compression: WinRK,
  SLIM and the PAQ6 family. | 
 
 
  | Maybe
  one day we have algorithms in use that have PPM's text power with
  Arithmetic's precision (PPMAri). And for the complex bitmap | 
 
 
  | and
  wave compression some pixel / sample weavers or replacers that will conquer
  the market | 
 
 
  | and
  convince users that lossy algorithms such as MP3 or JPG are bad since human
  memoris will fade - so our digital memories should not loose information,
  too. |
