摘要:
Picture signals entering a picture input device 4 are compressed by a picture compression device 5 for storing the resulting compressed picture data in a secondary storage device 7 via a primary storage device 6. The picture compression system is switched for recording a moving picture and for recording a still picture by switching picture compression parameters of the picture compression device 5 by a picture compression system switching device 10 between those for moving picture recording and those for still picture recording.

It is an object to provide an efficient transfer of content data. In a case of transferring the content data from a data transfer device on a primary recording medium side to a data recording device to record the content data in a secondary recording medium, a data compression system and a bit rate that are conformable to the data recording device are compared with a data compression system and a bit rate of the content data to be sent, so that a required transfer processing is brought into realization according to a result of the comparison. For instance, when both the data compression systems are equal, and the bit rate of the content data is not more than the bit rate that is conformable to the data recording device, the content data is sent as it is in an encrypted compressed data state.

Picture data composed of a color palette storage address and palette number data is read from memory. On the basis of the color palette storage address, a color palette is taken from among one or more color palettes stored in the memory. The picture data is colored according to the extracted color palette for each piece of the palette number data.

A mathematical operation processing apparatus is disclosed by which the supply of an operand which is performed based on condition codes by a plurality of mathematical operations can be performed at a high speed. The mathematical operation processing apparatus includes a plurality of computing elements configured to perform different mathematical operations different from one another and produce mathematical operation results of the mathematical operations and condition codes. A condition code set register retains the condition codes produced simultaneously by the computing elements as a condition code set. A condition code conversion section performs a predetermined conversion for the condition code set and outputs a result of the conversion as a conversion condition code set. An operand supplying section supplies an operand for the mathematical operations in the computing elements based on the conversion condition code set.

摘要:
Input data (plain text data or encrypted text data) are latched according to a clock CLK1 and, after initial transposition thereof, the data are outputted from a selector. The lower-order bits of the output data from the selector are processed through expanded transposition and then are calculated together with key data K1 in an XOR circuit, and the result data are latched according to a clock CLK2. The latched 48-bit data are divided into eight 6-bits data, each of which is then replaced with 4-bit data, and after combination thereof, the data are transposed. In the calculations of second and subsequent stages, the data obtained through replacement and combination in a replacement/combination circuit are latched according to the clock CLK1 and then are outputted from the selector. And after completion of the 16th-stage calculation, the data replaced in a replacement circuit are inversely transposed.
