However, most PAL games are using completely different "random" centering values maybe caused by different developers trying to match the centering to the different TV Sets although it looks more as if the PAL developers just went amok: For PAL game developers, it may be recommended to add a screen centering option as found in Tomb Raider 3, for example.

This book is intended to be self contained. Sources are linked when appropriate, but you don't need to click on them to understand the material. Information Theory Data compression is the art of reducing the number of bits needed to store or transmit data.

Compression can be either lossless or lossy. Losslessly compressed data can be decompressed to exactly its original value. An example is Morse Code. Each letter of the alphabet is coded as a sequence of dots and dashes.

The most common letters in English like E and T receive the shortest codes. The least common like J, Q, X, and Z are assigned the longest codes. All data compression algorithms consist of at least a model and a coder with optional preprocessing transforms.

A model estimates the probability distribution E is more common than Z. The coder assigns shorter codes to the more likely symbols. There are efficient and optimal solutions to the coding problem.

However, optimal modeling has been proven not computable. Modeling or equivalently, prediction is both an artificial intelligence AI problem and an art. Lossy compression discards "unimportant" data, for example, details of an image or audio clip that are not perceptible to the eye or ear.

The human eye is less sensitive to fine detail between colors of equal brightness like red and green than it is to brightness black and white. Thus, the color signal is transmitted with less resolution over a narrower frequency band than the monochrome signal. Lossy compression consists of a transform to separate important from unimportant data, followed by lossless compression of the important part and discarding the rest.

The transform is an AI problem because it requires understanding what the human brain can and cannot perceive. Information theory places hard limits on what can and cannot be compressed losslessly, and by how much: There is no such thing as a "universal" compression algorithm that is guaranteed to compress any input, or even any input above a certain size.

In particular, it is not possible to compress random data or compress recursively. Efficient and optimal codes are known. Data has a universal but uncomputable probability distribution.

Specifically, any string x has probability about 2- M where M is the shortest possible description of x, and M is the length of M in bits, almost independent of the language in which M is written. However there is no general procedure for finding M or even estimating M in any language.

There is no algorithm that tests for randomness or tells you whether a string can be compressed any further. No Universal Compression This is proved by the counting argument.

Suppose there were a compression algorithm that could compress all strings of at least a certain size, say, n bits. There are exactly 2n different binary strings of length n. A universal compressor would have to encode each input differently.

Otherwise, if two inputs compressed to the same output, then the decompresser would not be able to decompress that output correctly. However there are only 2n - 1 binary strings shorter than n bits.

In fact, the vast majority of strings cannot be compressed by very much. The fraction of strings that can be compressed from n bits to m bits is at most 2m - n. For example, less than 0. Every compressor that can compress any input must also expand some of its input. However, the expansion never needs to be more than one symbol.

Any compression algorithm can be modified by adding one bit to indicate that the rest of the data is stored uncompressed. The counting argument applies to systems that would recursively compress their own output. In general, compressed data appears random to the algorithm that compressed it so that it cannot be compressed again.

Assume our model is that each digit occurs with probability 0.MAT The Division Algorithm and Integers mod p The Division Algorithm Theorem The Division Algorithm Let a be an integer and d a positive integer, then there are unique integers q and r, with 0 # r.
