Transmission apparatus, communication system, and transmission method
First Claim
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.

Abstract
The present technology relates to a communication system, and a transmission method that a restoration time from a state that a transmission of a signal between AC-coupled apparatuses is suspended can be shortened without increasing a power consumption.
A first control signal is transmitted via the second signal line in a case where a transmission of the signal via the first signal line is restored from a suspended state, and that a transmission of a charging signal that charges an AC coupling capacitance serially connected to the first signal line via the first signal line is started before a timing when the transmission of the first control signal is ended. The present technology is applicable, for example, to a communication system in conformity with the eDP standard.

10. A transmission method, the method comprising:
-
determining, with a communication control circuitry, whether a transmission of a signal from a communication circuitry to a reception apparatus via a first signal line will be restored to an active state from a suspended state; responsive to determining the transmission of the signal from the communication circuitry to the reception apparatus will be restored to the active state from the suspended state, controlling, with the communication control circuitry, the communication circuitry to transmit a predetermined control signal via a second signal line; and controlling, with the communication control circuitry, 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 predetermined control signal is ended.

11. A communication system, comprising:
-
a transmission apparatus; and a reception apparatus connected to the transmission apparatus via a first signal line and a second signal line and AC-coupled to the transmission apparatus via the first signal line, the transmission apparatus including a communication unit that transmits a signal via a first signal line and a second signal line to the reception apparatus, and a communication control unit that controls transmission of the signal to the reception apparatus, the communication control unit controlling such that a first control signal is transmitted via the second signal line in a case where a transmission of the signal via the first signal line is restored from a suspended state, and that a transmission of a charging signal that charges an AC coupling capacitance serially connected to the first signal line via the first signal line is started before a timing when the transmission of the first control signal is ended. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
