PURPOSE: To suppress gradation degradation in the case of digital image transmission.
CONSTITUTION: There is one kind of a unique word UW and it is defined as '00' (which is a 16-adic description, 'FF' is available as well) and shared for a vertical synchronizing signal a horizontal synchronizing signal. The next data of this unique word UW are a synchronizing signal identification code expressing whether it is the vertical synchronizing signal or the horizontal synchronizing signal, VU expresses the vertical synchronizing signal and HU expresses the horizontal synchronizing signal. In the case of 8-bit data, the VU is decided as '00000000' (full bit description) and the HU is decided as '00000001' (full bit description as well), for example.
