Title:
COMMUNICATION DEVICE, ENDOSCOPE DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/144330
Kind Code:
A1
Abstract:
This communication device has a transmitter device (17) and a receiver device (19). The transmitter device (17) computes a DC balance value of input data, compares the DC balance value with a cumulative value thereof, and compares the sign of the DC balance value with the sign of the cumulative value. If the signs are identical, a first value and a second value of all bits of the input data are exchanged in order to generate intermediate data, and predetermined information indicating all-bit-inversion is generated. If the signs are different, processing which treats the input data as intermediate data is performed so as to transmit the same using a serial signal. The receiver device (19) exchanges the first value and the second value of all bits of the received data to generate output data if the predetermined information has been generated, and treats the received data as output data if the predetermined information has not been generated.
