专利汇可以提供Information storage device专利检索,专利查询,专利分析的服务。并且PURPOSE: To make effective use of the capability of an error-correcting code by counting the time interval between the detectings of a synchronized part of data and the succeeding synchronized part, and identifying the position of an error in case the value of the said counting is not of a prescribed value.
CONSTITUTION: A signal (c) is outputted by a counter 7 at every interval between the synchronizing parts 2, inverted by an inverter 16, and turns to be a signal (d), which is inputted to a gate 17 along with a synchronizing signal detecting signal (b). The output (e) of the gate 17 comes to low at the time when a synchronizing part is detected at a position other than the prescribed positions of the parts 2. A register 11 stores the content of a register 10 and a frame number that is the output of a counter 9 at the time when the signal (e) turns to be '0'. Accordingly, the register 11 outputs a frame number (i) corresponding to the synchronized part 2 detected immediately preceding an error A in which a bit slip occurs by its output (x), and outputs one (i+2) corresponding to the part 2 detected for the first time after the said bit slip by its output (y). When receiving the outputs (x) and (y), a lost flag generating part 12 generates a lost flag in a data in a frame that includes the bit slip.
