Kb. mostanra durrant el a zagyam!

Írom ööö inkább fordítom azt a telibevert szakdolgozatot. A H.264-et magyarázó részben találtam egy ilyen szakaszt, amit egyszerűen képtelen vagyok értelmezni:

Quantization Parameters
Perhaps the most important factor in a multimedia compression specifi-
cation is the coding gain obtained due to quantization. Under the H.264
standard, a nonlinear quantization process is supported, with an approximate
12 percent increase in the magnitude of the step size from one
quantization parameter to another. In addition, a total of 52 quantization
parameters are supported by the standard, which enhances the coding
gain obtainable in the quantization process.
Although the H.264 standard supports a wide range of network operations
from ADSL to cable television, its higher complexity than MPEG-2
resulted in the vast majority of current set-top boxes supporting the earlier
standard. As the processing power of chips increases, we can reasonably
expect the H.264 standard to have an increased level of implementation.
Legalábbis ez a kvantálási paramétert nagyon nem értem! Mi a halál ez?!
