Data recorder-reproducer and bit map data processing method, control program processing method and setting data processing method of data recorder-reproducer

摘要

In a data recorder-reproducer, and a bit map data processing method, a control program processing method and a setting data processing method of the data recorder-reproducer, bit map data supplied from the external is taken in, and the taken bit map data is superimposed upon data which is reproduced from a recording medium or is input from the external. In addition, first program data stored in a rewritable storing means is rewritten into second control program data supplied from the external. Furthermore, settings of an input/output means is changed based on the setting data supplied from the external.
