Abstract

A method of controlling data transfer, a method of controlling content transfer, a method of obtaining content processing information, and a system for transferring content are provided. The method of controlling data transfer in a data interoperable environment includes: receiving a request for transmitting data from a client; gathering information on entities which are to participate in transmitting data; forming a chain including at least two entities by using the gathered information on the entities; transmitting a plurality of data through the chain; and receiving an event message for representing a transmission status of the data transmitted from at least one of the entities included in the chain. Accordingly, it is possible to control a transmission of the data so that the plurality of data can be transmitted through a single session and to receive the transmission status of the data as an event message.

Claims

1. A computer-implemented method comprising:

receiving, at a first device, a message including a domain identifier identifying a domain and capability information describing a capability of a second device;

determining, using the receiving message, if the first device is to be designated as a controller of the domain; and

designating the first device as the controller device based on the determination.

2. The method of claim 1, wherein determining if the first device is to be designated as the controller of the domain further comprises:

comparing a capability of the first device with the capability of the second device;

broadcasting data describing the capability of the first device to a third device if the capability of the first device is greater than the capability of the second device; and

pausing for a predetermined amount of time if the capability of the first device is less than or equal to the capability of the second device.

3. The method of claim 1, wherein the first device is designated as the controller based on the capability of the first device being highest among capabilities of devices associated with the domain.

4. A device comprising:

an interface configured to;

receive, at a first device, a message including a domain identifier identifying a domain and capability information describing a capability of a second device; and

a processor configured to;

determine, using the receiving message, if the first device is to be designated as a controller of the domain, and

designate the first device as the controller device based on the determination.

5. The device of claim 4, wherein determining if the first device is to be designated as the controller of the domain further comprises:

comparing a capability of the first device with the capability of the second device;

broadcasting data describing the capability of the first device to a third device if the capability of the first device is greater than the capability of the second device; and

pausing for a predetermined amount of time if the capability of the first device is less than or equal to the capability of the second device.

6. The device of claim 4, wherein the first device is designated as the controller based on the capability of the first device being highest among capabilities of devices associated with the domain.

7. A system comprising:

one or more computers;

a computer-readable medium coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, causes the one or more computers to perform operations comprising;

receiving, at a first device, a message including a domain identifier identifying a domain and capability information describing a capability of a second device,

determining, using the receiving message, if the first device is to be designated as a controller of the domain, and

designating the first device as the controller device based on the determination.

8. The system of claim 7, wherein determining if the first device is to be designated as the controller of the domain further comprises:

comparing a capability of the first device with the capability of the second device;

broadcasting data describing the capability of the first device to a third device if the capability of the first device is greater than the capability of the second device; and

pausing for a predetermined amount of time if the capability of the first device is less than or equal to the capability of the second device.

9. The system of claim 7, wherein the first device is designated as the controller based on the capability of the first device being highest among capabilities of devices associated with the domain.
