Residual coefficients are primarily the transform coefficients of the difference between a macroblock and its motion
compensated version,after they have been quantized and entropy coded.Our experiments have shown that these
residual coefficients do carry a certain amount of “residual visual information” that may convey to an adversary the
content of the compressed video if not properly secured.Thus,it becomes necessary to encrypt the residual information.
Figure 2 shows that without having to decoding the reference frame or motion vectors,the luma residue coefficients of a
P frame will provide an adversary a delineation of the original frame.Therefore,we need to protect the residual
coefficients.However,further experiments reveal that not all of the luma and chroma coefficients need to be secured.
Figure 3 demonstrates the effect of scrambling all the residual luma and chroma DC coefficients of a P frame when its
motion vectors and reference frame have not been encrypted.As can be seen,for the most part encrypting the DC
coefficients was sufficient to obscure many of the details in the frame.Any information that did leak through was due to
unsecured motion vectors and reference frame.

The coefficients of variation were less than 10% and therefore confirm that the low concentration level can be established as significantly lower than the maximum permissible value.This means that whenever the concentration found in one control analysis of a product using this method is lower than 50% of the recommended value,the product is acceptable.If it is higher,further analysis is necessary using multiple samples to establish if the product can be released or has to be discarded.

find a third degree polynomial with real coefficients that has 2,3-i as zeros

英语翻译
The zeros of polynomials with real coefficients can be real of imaginary numbers,but imaginary zeros must occur in pairs.
If a real zero accurs n times,it is said to have multiplicity n.If a zero of a polynomial has even multiplicity,its graph touches,but does not cross,the x-axis.
The multiplicity of a real zero is counted toward the total number of zeros.
