Abstract

A method for transmitting contents and user'"'"'s interactions among multiple devices is provided. The method includes determining a group of object devices including a portion of the plurality of object devices, transmitting the data to the object devices of the determined group, receiving confirmation information from the object device which completes receiving of the data, among the object devices of the determined group, determining a clone device based on the received confirmation information. The transmitted clone information is used to transmit the data from the determined clone device to at least one object device which is not included in the object devices of the determined group among the plurality of object devices.

Claims

1. A method of transmitting data from a host device to a plurality of object devices, the method comprising:

determining a group of object devices comprising a portion of the plurality of object devices;

transmitting the data to the object devices of the determined group;

receiving confirmation information from an object device which completes receiving of the data, among the object devices of the determined group;

determining a clone device based on the received confirmation information; and

transmitting clone information to the determined clone device,

wherein the transmitted clone information is used to transmit the data from the determined clone device to at least one of the plurality of object devices which is not included in the object devices of the determined group among the plurality of object devices.

2. The method of claim 1, further comprising:

transmitting, if the host device receives the confirmation information, the data to at least one of other object devices, which are not included in the object devices of the determined group, among the plurality of object devices.

3. The method of claim 1,

wherein the determining of the clone device comprises determining a plurality of clone devices, and

wherein other object devices not included in the object devices of the determined group among the plurality of the object devices, to which the data is transmitted, are divided according to the plurality of clone devices.

4. The method of claim 1, wherein, if a size of the data is smaller than a predetermined size, the data is simultaneously transmitted to the plurality of object devices.

5. The method of claim 1,

wherein the data comprises a plurality of packets, and

wherein the transmitting of the data comprises:

transmitting a packet among the plurality of packets with an identifier to another object device among the object devices of the determined group according to a user diagram protocol (UDP) method;

receiving a response comprising the identifier from the other object device among the object devices of the determined group; and

ending, if the response is received, a transmission process of the packet.

6. The method of claim 5, further comprising:

re-transmitting, if the response is not received until a predetermined time elapses from a time when the packet with the identifier is transmitted to the object device among the object devices of the determined group according to the UDP method, the packet according to a transmission control protocol (TCP) method.

13. A non-transitory computer-readable recording medium having recorded thereon a program executed by at least one processor to perform the method of claim 1.

15. The method of claim 5, wherein the transmitting of the packet among the plurality of packets with the identifier occurs prior to receiving the response of a previously transmitted packet with a sequentially lower identifier than the identifier.

7. A method of transmitting and receiving data from a device, the method comprising:

receiving the data from a host device;

transmitting, if the receiving of the data is completed, confirmation information to the host device;

receiving clone information from the host device; and

transmitting the data to at least one object device based on the received clone information,

wherein the received clone information comprises information about the at least one object device which are to receive the data among a plurality of object devices included in a network.

8. The method of claim 7, further comprising:

transmitting, if confirmation information indicating that the receiving of the data is completed is received from the at least one object device, the confirmation information received from the at least one object device to the host device.

9. The method of claim 7, wherein the transmitted confirmation information is used to determine a clone device to which the received clone information is transmitted from the host device.

10. The method of claim 7, wherein the data is provided to a portion of the plurality of object devices included in the network.

11. The method of claim 7,

wherein the data comprises a plurality of packets, and

wherein the transmitting of the data comprises:

transmitting a packet among the plurality of packets with an identifier to an object device among the at least one object device according to a user diagram protocol (UDP) method;

receiving a response comprising the identifier from the object device among the at least one object device; and

ending, if the response is received, a transmission process of the packet.

12. The method of claim 11, further comprising:

re-transmitting, if the response is not received until a predetermined time elapses from a time when the packet with the identifier is transmitted to the object device among the at least one object device according to the UDP method, the packets according to a transmission control protocol (TCP) method.

14. A non-transitory computer-readable recording medium having recorded thereon a program executed by at least one processor to perform the method of claim 7.

16. The method of claim 11, wherein the transmitting of the packet among the plurality of packets with the identifier occurs prior to receiving the response of a previously transmitted packet with a sequentially lower identifier than the identifier.

17. A host device for transmitting data to a group of object devices, the device comprising:

a transceiver configured to transmit and receive information from a plurality of object devices; and

at least one processor configured to;

determine the group of object devices comprising a portion of the plurality of object devices,

control the transceiver to transmit the data to the determined group of object devices,

control the transceiver to receive confirmation information from an object device which completes receiving of the data, among the determined group of object devices,

determine a clone device based on the received confirmation information, and

control the transceiver to transmit clone information to the determined clone device,

wherein the transmitted clone information is used to transmit the data from the determined clone device to at least one of the plurality of object devices which is not included in the determined group of object devices among the plurality of object devices.

18. The device of claim 17, wherein the at least one processor is further configured to control the transceiver to transmit, if the host device receives the confirmation information, the data to at least one of other object devices, which are not included in the determined group of object devices among the plurality of object devices.

19. The device of claim 17,

wherein the at least one processor is further configured to determine the clone device from a plurality of clone devices, and

wherein other object devices not included in the determined group of object devices among the plurality of the object devices, to which the data is transmitted, are divided according to the plurality of clone devices.

20. The device of claim 17, wherein, if a size of the data is smaller than a predetermined size, the data is simultaneously transmitted to the plurality of object devices.
