Während die moderne Kryptologie mathematisch strenge Konzepte und Methoden aus der Komplexitätstheorie verwendet, ist die Forschung in der Komplexitätstheorie wiederum oft durch Fragen und Probleme motiviert, die aus der Kryptologie stammen. Das vorliegende Buch hebt die enge Verflechtung dieser verwandten (doch oft separat behandelten) Gebiete hervor, deren Symbiose guy als „Kryptokomplexität" bezeichnen könnte.

Resource coding idea has as its objective the characterization of the optimum functionality plausible in idealized verbal exchange structures which needs to code a knowledge resource for transmission over a electronic verbal exchange or garage channel for transmission to a consumer. The consumer needs to decode the data right into a shape that could be a reliable approximation to the unique.

Example text

More high-definition services will be launched during the next few years. Plasma, LCD, or LED flat screens are available in sizes up to 60 inches diagonal. If you want to go larger than that, you will need to consider a projection system. At large screen sizes, it helps to increase the resolution of the image that is being projected, and that may require some special hardware to scale it up and interpolate the additional pixels. At these increased screen sizes, any artifacts that result from the compression will be very obvious.

Trying to deploy it in unsuitable circumstances leads to difficulty later in the production and consumption cycle. 1 Origination Stage Video compression should be avoided at the origination stage. Some cameras compress the video as it is written to tape or disk inside the camera. These devices never yield an uncompressed output. The consequence is that any content you shoot with such a camera will probably turn out to be totally useless for anything other than home movies. For example, suppose you are shooting some training video and you want to color key the background.

The time axis gives us extra opportunities to save space by looking for redundancy across multiple images. This kind of compression is always lossy. It is founded on the concept of looking for differences between successive images and describing those differences, without having to repeat the description of any part of the image that is unchanged.
