    摘要: A data transmission system, permits data transmission without failure while ensuring a substantially constant picture quality or audio quality irrespective of the source of data. The data transmission system transmits data after conversion thereof into digital data and compression of the same. In the system, the distortion in data to be transmitted is measured, and the quantization step size is controlled according to the measured distortion to hold the distortion constant, thus permitting data transmission while maintaining constant quality of the transmitted data irrespective of the data source kind.

    摘要: In the recording/reproducing of digital audio signals, errors are detected and corrected by using two parity words, one arranged at the center of the block formed of data words and the arranged at one end of the block. The probability that uncorrectable error will be present in the center of the block is relatively high, so placing the parity word there prevents loss of the more valuable data. Maximum correctable burst errors are determined by the length of the block, so placing the other parity word on the end of the block lengthens it and improves burst error correction. The parity words are arranged as indicated before adding a cyclic redundancy check (CRC) code to the data signal and then modulation coding the signal before recording. During playback, the reproduced signal is demodulated and the CRC code used to detect errors for which error pointers are generated. The reproduced data is read into memories in accordance with generated addresses and the pointers prevent the writing in of words found to be in error, which error words are subsequently corrected if possible using parity codes originally encoded into the signals prior to recording.

    摘要: An information processing system, an information processing apparatus, an information processing method, and an information record medium that are controlled to generate an operation effect sound that differs for each user of a card upon an operation for electronic money are provided. A card 10 records user information 12, balance information 13, and audio data 14. The card 10 makes a settlement of electronic money with a vending machine 20 to buy a commodity. When the card 10 is presented to the vending machine 20, it reads the user information 12, the balance information 13, and the audio data 14 from the card 10 through wireless communications. The vending machine 20 makes a settlement on the basis of both information of the commodity that a user has selected and the balance information 13. As a result, the vending machine 20 provides the selected commodity to the user. On the other hand, with audio data 14, at a predetermined timing of the settlement, a predetermined sound is output. Audio data may be stored only in the vending machine 20 or both in the card 10 and in the vending machine 20. A sound that differs for each user and for each event is output.

    摘要: 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.
