The present invention allows a reduction in power consumed by communications between devices over a network. A transmission-side device transmits a signal including a wake up signal, path information, and a main data signal in this order to the following relay device (switch/router). The relay device activates a circuit in a standby state on a path on the basis of the wake up signal and the path information. Relay devices on the path are sequentially activated, and the main data signal is finally received by a reception-side device.
1 . A transmission device comprising:
circuitry configured to
output a wake up signal, path information, and a main data signal in this order; and
transmit a signal output from the circuitry,
wherein the circuitry outputs the wake up signal over a period longer than an inactive period of an intermittent operation of reception determination made by a device configured to receive the signal transmitted from the circuitry.
2 . The transmission device according to claim 1 ,
wherein the circuitry starts to output the path information at a predetermined interval after end of the output of the wake up signal.
3 . The transmission device according to claim 1 ,
wherein the circuitry stops outputting the wake up signal based on a reception notification transmitted from a device that receives the signal transmitted from the circuitry after start of the output of the wake up signal, and then starts to output the path information.
4 . The transmission device according to claim 1 ,
wherein the circuitry starts to output the main data signal at a predetermined interval after end of the output of the path information.
5 . The transmission device according to claim 1 ,
wherein the circuitry starts to output, after end of the output of the path information, the main data signal based on a ready notification transmitted from a device that receives the signal transmitted from the circuitry.
6 . A transmission method, executed by at least one processor, the method comprising:
outputting a wake up signal, path information, and a main data signal in this order; and
transmitting the wake up signal, the path information, and the main data signal that have been output,
wherein the wake up signal is output over a period longer than an inactive period of an intermittent operation of reception determination made by a device configured to receive the transmitted wake up signal.
