Transmitter, transmission method, receiver, and reception method
First Claim
1. A transmitter, comprising:
- circuitry configured to;
transmit a given signal to a receiver in a detection mode of the transmitter, whereinthe given signal is transmitted to the receiver via a first waveguide and a second waveguide, andthe first waveguide is on a side of the transmitter and the second waveguide is on a side of the receiver;
detect, in the detection mode, a contact between the first waveguide and the second waveguide based on a level of the given signal, received by the receiver, that is one of equal to a first threshold value or larger than the first threshold value;
switch from the detection mode to a communication mode of the transmitter based on the detected contact; and
transmit, in the communication mode, a modulated signal via the first waveguide and the second waveguide to the receiver.

Abstract
The present technology relates to a transmitter, a transmission method, a receiver, and a reception method that can keep upsizing and cost increase to a minimum. The transmitter and the receiver have a detection mode and a communication mode as operation modes. The detection mode detects contact between a first waveguide on the side of the transmitter and a second waveguide on the side of the receiver. The communication mode sends or receives a modulated signal, acquired through frequency conversion of a baseband signal, via the first and second waveguides. The transmitter sends a given signal to the first waveguide in the detection mode. The transmitter and the receiver go from the detection mode to the communication mode in response to a given signal received by the receiver via the second waveguide and send and receive the modulated signal via the first and second waveguides in the communication mode.
