Repeater device and repeating method
View Patent ↗In a repeater device: a communication device receives position information of a forwarding source device and a forwarding destination device using a first communication scheme; based on the position information of the forwarding source device, a moving mechanism moves the repeater device to a position at which it is capable of communicating with the forwarding source device using a second communication scheme; the communication device receives data from the forwarding source device using the second communication scheme; a storage device stores the data; based on the position information of the forwarding destination device received by the communication device, the moving mechanism moves the repeater device to a position at which it is capable of communicating with the forwarding destination device using the second communication scheme, and the communication device transmits the data stored in the storage device to the forwarding destination device using the second communication scheme.
1. A repeater device, comprising:
a moving mechanism configured to move the repeater device;
a communication device configured to communicate with an external device by switching between a first communication scheme and a second communication scheme, the second communication scheme having a narrower communication range and a greater per-unit-time data forwarding capacity than the first communication scheme;
a storage device for storing data; and
an encoding device configured to encode video data,
wherein the communication device is configured to receive, using the first communication scheme, position information of a forwarding source device and position information of a forwarding destination device,
based on the position information of the forwarding source device received by the communication device, the moving mechanism is configured to move the repeater device to a position at which the repeater device is capable of communicating with the forwarding source device using the second communication scheme,
the communication device is configured to receive, using the second communication scheme, first video data transmitted from the forwarding source device,
the encoding device is configured to generate second video data by encoding the first video data using a video encoding method different than a video encoding method of the first video data,
the storage device is configured to store the second video data,
based on the position information of the forwarding destination device received by the communication device, the moving mechanism is configured to move the repeater device to a position at which the repeater device is capable of communicating with the forwarding destination device using the second communication scheme,
the storage device is configured to continue storing the second video data while the repeater device moves to the position at which the repeater device is capable of communicating with the forwarding destination device using the second communication scheme,
the communication device is configured to transmit, using the second communication scheme, the second video data stored in the storage device, to the forwarding destination device, and
the repeater device is selected by the forwarding source device based on information indicating a path of movement of the repeater device, information indicating a path of movement of another repeater device, and the position information of the forwarding destination device.
2. A repeating method performed by a repeater device, the repeating method comprising:
receiving, using a first communication scheme, position information of a forwarding source device and position information of a forwarding destination device;
based on the position information of the forwarding source device received, moving to a position at which communication with the forwarding source device using a second communication scheme is possible, the second communication scheme having a narrower communication range and a greater per-unit-time data forwarding capacity than the first communication scheme;
receiving, using the second communication scheme, first video data transmitted from the forwarding source device;
generating second video data by encoding the received first video data using a video encoding method different than a video encoding method of the first video data, and storing the generated second video data;
based on the position information of the forwarding destination device received, moving to a position at which communication with the forwarding destination device using the second communication scheme is possible;
continuing storing the second video data while the repeater device moves to the position at which communication with the forwarding destination device using the second communication scheme is possible; and
transmitting, using the second communication scheme, the stored second video data, to the forwarding destination device,
wherein the repeater device is selected by the forwarding source device based on information indicating a path of movement of the repeater device, information indicating a path of movement of another repeater device, and the position information of the forwarding destination device.
