    摘要： A data transfer apparatus and a data transfer system intended to transfer data continuously input or output to/from a main memory without any interruption and to transfer continuous data on a general-purpose bus such as a PCI bus, and a recording medium storing a program that commands a computer to execute all or some of functions of each component of the data transfer apparatus or the data transfer system. If it is supposed that a capacity of a write buffer memory 4 is CAPW, an input rate of continuously input data is T1, and a maximum assumed value of an interval of bus access permissions issued by a CPU 1 is TW, data omissions can be prevented by setting CAPW, T1 and TW at values that satisfy: CAPW≧TW×T1

    摘要： This invention relates to a time code recording and reproducing apparatus for recording and reproducing time codes corresponding to a digital signal. Time code converting means (100) converts a first time code into a second time code. A frame phase which occurs during the recording of input information is determined by frame timing generating means. A phase difference between a frame of the second time code and a recording frame is detected by phase difference detecting means (103). Phase difference correcting means (104) outputs a third time code on the basis of the detected phase difference. The input information is recorded together with the third time code. Thereby, the recording can be performed while the relation of the correspondence between the input information and the time code is held. In addition, the reproduction can be performed.
