  • Patent number: 8660963
    Abstract: The present invention can reliably prevent the contents of a recording medium from being illegally copied but allow them to be copied only for the purpose of personal use. The invention takes out title identifying information and medium identifying information of a DVD loaded on a hard-disk-containing DVD player and transmits those pieces of information to management server along with the apparatus identifying information of the hard-disk-containing DVD player so as to enquire about copying prohibition flag for a copying operation and control copying of the recorded contents of the DVD according to the copying prohibition flag. Thus, the invention prohibits copying when the management server judges that copying of the contents of the DVD by means of the hard-disk-containing DVD player is illegal, whereas it allows copying when the management server judges that copying of the contents of the DVD by means of the hard-disk-containing DVD player is for the purpose of personal use.

    Abstract: An image processing apparatus which may include a grayscale modulator forming a ?? modulator. The modulator may include an adder that adds the pixel value of an image and an output of a feedback arithmetic unit, a quantizing unit that quantizes an output of the adder and outputs a quantized value including a quantization error as the result of ?? modulation, a subtractor that calculates the quantization error, and the feedback arithmetic unit that filters the quantization error and outputs the filtering result to the adder. The filter coefficient of filtering by the feedback arithmetic unit may be determined such that the amplitude characteristics of noise shaping by the ?? modulator in a frequency band that is equal to or more than an intermediate frequency band are the inverse characteristics of the spatial frequency characteristics of the human eye.
