Abstract

A transfer device according to an embodiment transfers blocks generated by dividing a frame into pieces of data and adding a synchronization header each of the pieces of data. The blocks comprise a first, second and third blocks in this order. The transfer device is configured to acquire a first synchronization header in the first block, a second synchronization header in the second block and a third synchronization header in the third block, judge, in a case where a value of the second synchronization header is incorrect, as to whether or not the value of the second synchronization header can be estimated based on the first and the third synchronization headers so that the second block is consistent with the first and third blocks, and correct the second synchronization header into the estimated value.

Dependent claims

A data transfer device for transferring blocks generated by dividing a frame into pieces of data each having a first predetermined number of bits and adding a synchronization header having a second predetermined number of bits to each of the pieces of data obtained by the dividing, comprising:

a processing module for processing an operation of the data transfer device;
a buffer for storing a block to be transferred;
and
an interface for receiving and transmitting g data to and from the data transfer device, wherein:
the blocks comprises a first block, a second block, and a third block that are successively transferred in the stated order;
and
the processing module is configured to:
acquire a first synchronization header included in the first block, a second synchronization header included in the second block, and a third synchronization header included in the third block;
perform, in a case where a value of the second synchronization header is incorrect, a first judgment as to whether or not the value of the second synchronization header can be estimated based on the first synchronization header and the third synchronization header so that the second block is consistent with the first block and the third block;
and
correct the second synchronization header into the estimated value.
