    • An information reproducing apparatus for reproducing recorded data includes a buffer, a control device and a determining device. The buffer stores data blocks read out from a recording medium and includes first and second storage areas having respectively discontinuous storing and read addresses. The apparatus is controlled to execute in parallel a first process for storing the data blocks into the buffer and a second process for reading out the data blocks stored in the buffer to transfer the data blocks to a host apparatus. The determining device determines whether there are data in the first storage area to be transferred to the host apparatus by comparing a storing address in the buffer of the data which are being stored into the first storage area with a read address in the buffer of the data which are being read out from the first storage area. The first process is controlled so that a predetermined data block which has been read out from the recording medium is stored into the second storage area. When the predetermined data block is stored into the second storage area, the determining device does not compare the storing address in the buffer of the data which are being stored into the second storage area with the read address in the buffer of the data which are being read out from the buffer.
    • 用于再现记录数据的信息再现装置包括缓冲器,控制装置和确定装置。 缓冲器存储从记录介质读出的数据块,并且包括分别具有不连续存储和读取地址的第一和第二存储区域。 该装置被控制为并行执行用于将数据块存储到缓冲器中的第一处理和用于读出存储在缓冲器中的数据块的第二处理,以将数据块传送到主机装置。 确定装置通过将存储在第一存储区域中的数据的缓冲器中的存储地址与数据的缓冲器中的读取地址进行比较来确定是否存在要传送到主机设备的第一存储区域中的数据 它们正在从第一个存储区读出。 控制第一处理使得从记录介质读出的预定数据块被存储到第二存储区域中。 当预定数据块被存储到第二存储区域中时,确定装置不将存储在第二存储区域中的数据的缓冲器中的存储地址与正在被存储的数据的缓冲器中的读取地址进行比较 从缓冲区读出。

    • A communication apparatus which transmits data to a transmission destination, and receives, from the transmission destination, an acknowledgement indicating that the data has been received stores, in a memory, first specific data for specifying a plurality of transmission data, and transmission time data indicating transmission times of the plurality of transmission data. Based on second specific data contained in the acknowledgement, the communication apparatus searches the memory for first specific data for specifying transmission data corresponding to the acknowledgement, and calculates a round trip time based on the transmission time of the transmission data specified by the found first specific data, and a reception time at which the acknowledgement is received.
