摘要： To provide a digital data transmitting apparatus and a digital data receiving apparatus that can realize, even when a transmission channel characteristic changes because of aged deterioration or the like of a relay, improvement of a reception performance following the change.A transmitting apparatus 1 generates a multiplexing frame formed by N slots including control information, data, outer parities, stuff bits, and inner parities and added with synchronization, pilot, and a transmission control signal and a parity and transmits data of the respective slots in a transmission system designated by the transmission control signal. In this case, pilot signals are symbols allocated to all signal points in order determined in advance for each of modulation schemes. A receiving apparatus 2 rewrites a phase error table 214 to calculate a phase error and performs synchronous detection according to the pilot signals. The receiving apparatus 2 also rewrites a likelihood table 235 to perform inner code decoding. Consequently, since reception processing adapted to distortion of a transmission channel characteristic can be performed, improvement of a reception performance can be realized.

摘要： A character display apparatus searches through a cache means for vector font data which match character attributes of a character to be displayed to acquire the vector font data, and, when no vector font data which match the character attributes of the character to be displayed exist in the cache means, acquires the vector font data from a large-volume storage means. If there exists no corresponding luminance image data in the cache means, the character display apparatus acquires luminance image data generated from the vector font data. If there exists no corresponding display image in the cache means, the character display apparatus acquires display character image data generated from the luminance image data. The character display apparatus displays the display image which is thus acquired and which matches the character attributes of the character to be displayed on a display device.
