an application component element describing a role of an application component, and

a capability element.

2. The method according to claim 1, wherein the ESG data is service type information, schedule information, related content information, or related component information of the broadcast service.

3. The method according to claim 1, further comprising transmitting information on modified content of the ESG data to the companion device,

wherein the information on modified content comprises added, modified, or deleted ESG data.

4. The method according to claim 1, further comprising:

transmitting an ID list of broadcast services included in the ESG data to the companion device;

receiving a request for ESG data related to specific broadcast services identified according to at least one ID of the ID list, from the companion device; and

transmitting the requested ESG data related to specific broadcast services to the companion device.

5. The method according to claim 1, further comprising:

receiving a request for an ID of a currently watched broadcast service from the companion device;

transmitting the requested ID of the currently watched broadcast service to the companion device;

receiving a request for ESG data related to the currently watched service; and
