Abstract

The invention discloses a data receiving apparatus, a data transfer apparatus and a data receiving method. The data receiving device includes a receiving unit, an inverse conversion unit and an error correction unit. The receiving unit receives converted data, which is obtained by converting data including transfer data of a plurality of bits, and an error detection code for error detection of the transfer data, according to a predetermined first procedure. The inverse conversion unit inversely converts the received converted data according to a predetermined second procedure. If it is impossible for the inverse conversion unit to inversely convert the converted data, if it is possible for the inverse conversion unit to inversely convert inverted data obtained by inverting a portion of the bits of the converted data, and if an error is not detected in data obtained by inversely converting the inverted data based on the error detection code, the error correction unit performs error correction by inversely converting the inverted data.

Description

technical field [0001] The present disclosure relates to a data receiving device, a data transmission device, and a data receiving method. Background technique [0002] For example, JP 2008-294757A (corresponding to US 2008 / 0294966A and CN101312387A) describes a data transmission device, which performs Equalization processing to perform 8B / 10B conversion, thereby improving DC balance. [0003] The data transmission device described in JP 2008-294757A includes a transmission section that transmits data, and a reception section that receives data transmitted by the transmission section through a transmission channel. The transmission section forms a frame having a predetermined length, performs DC balance conversion on the frame, and adds an error correction code enabling error detection and error correction for transmission to the reception section. The reception section is configured to perform inverse DC balance conversion and error detection processing on received data, ...
