1. A transmission apparatus, comprising:

  • a communication circuitry configured totransmit a signal to a reception apparatus via a first signal line, the reception apparatus being AC-coupled to the transmission apparatus via the first signal line, andtransmit a first control signal to the reception apparatus via a second signal line that is different than the first signal line; and

    a communication control circuitry configured tocontrol transmission of the signal to the reception apparatus,determine whether the transmission of the signal to the reception apparatus will be restored from a suspended state,responsive to determining that the transmission of the signal to the reception apparatus will be restored from the suspended state, control the communication circuitry to transmit the first control signal via the second signal line, andcontrol the communication circuitry to transmit a charging signal that charges an AC coupling capacitance serially connected to the first signal line via the first signal line before a timing when the transmission of the first control signal is ended.
