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.

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.

Disclosed is an information display method whereby an information processing apparatus displays a map on a display screen such that a cursor is displayed at a position measured as the current position of a position indication object on the map. The method includes the steps of, when the moving speed of the position indication object is equal to or less than a threshold speed, scrolling the map on the display screen in accordance with the movement of the position indication object in a first display mode, and when the moving speed of the position indication object is greater than the threshold speed, fixing the map on the display screen in a second display mode or reducing the speed of scrolling the map on the display screen so that the scrolling speed is less than that in the first display mode.
