    摘要： A printing apparatus having two character generators, one which generates characters common to a plurality of countries, comprises a keyboard for entering character codes, a first character generator for producing certain character patterns representing certain character codes common to a plurality of countries, and a second character generator for producing other character patterns representing other character codes. A buffer stores the character codes entered by a keyboard and a selection signal generator generates a selection signal in dependence on each character code stored in the buffer. The selection signal indicates that the second character generator is to be utilized to produce the other character patterns represented by the other character codes. A processor controls the operation sequence ofthe apparatus. The buffer is responsive in the absence of generation of the selection signal by the generator to access the first character generator to produce one of the certain character patterns and the processor is responsive to generation of a selection signal by the generator to access the second character generator to produce one of the other character patterns.

    摘要： A standard definition (SD) corresponding image is derived from a high definition (HD) image by performing a vertical line sub-sampling for every field with a ratio of an N:1, where N is an odd number greater than 1. One of the simple sub-sampling methods, the pyramidal coding method and the sub-band coding method may be used. For first fields, every third line is derived. For the remaining fields, every third line positioned at the center of the lines derived from the first field is derived by taking positional relation thereof on a reproduced image screen into consideration. As a result, it is possible to obtain an SD corresponding image having an unbroken interlace structure.
