In transmission of channel-coded serial data, early establishment of symbol synchronization between a transmitter and a receiver is achieved while reducing coding loss in transmission of valid data. In an idle period for not transmitting the valid data, a transmitting circuit selects first channel coding (e.g. 8B/10B coding) enabling early establishment of synchronization and transmits a synchronization symbol encoded using the first channel coding. In response to this, a receiving circuit establishes and maintains symbol synchronization. When the valid data is transmitted, the transmitting circuit transmits a symbol indicating a packet start position, selects second channel coding (e.g. 64B/66B coding) having less coding loss than the first channel coding, and transmits the valid data encoded using the second channel coding. Upon reception of the symbol indicating the packet start position, the receiving circuit switches to reception using the second channel coding and receives the valid data.
