PURPOSE:To ensure a number of addresses, by providing an addressable function to unnecessary information bits in reducing an error correcting code and to a bit exclusive for address designation. CONSTITUTION:The unnecessary information bits in reducing an error correcting code, i.e., 103 bits of the unnecessary information bits at the left part in a figure, which are used only in forming a BCH code and not used and transmitted as the specific information bits are used for the address designation in addition to the bits exclusive for the address designation. Further, for example, the bits exclusive for the address designation are used for the accessing areas having receivers as the high-order address and the unnecessary information bits are used for individual accessing as the low-order address. |
