Apparatus for transmitting broadcast signals, apparatus for receiving broadcast signals, method for transmitting broadcast signals and method for receiving broadcast signals

An apparatus for providing interactive contents based on personal interests, the apparatus comprising:

• a paring module configured to pair with a companion device;
• a receiving module configured to receive a Profiles, Demographics and Interests (PDI) table via broadcast signals,
• wherein the PDI table includes plural PDI questions related to personal interests for interactive contents, and
• wherein the PDI table includes an identifier (ID) that identifies the PDI table;
• an answer obtaining module configured to obtain an answer for at least one of the PDI questions;
• a PDI storing module configured to store the obtained answer in the PDI table;
• and
• a companion device module configured to deliver the PDI table having the obtained answer to the paired companion device according to a Universal Plug and Play (UPnP) service for delivering the PDI table,
• wherein the UPnP service has a first UPnP action and a second UPnP action, and
• wherein, to deliver the PDI table, the companion device module is further configured to:
• receive a first request including protocol version information of the UPnP service thereby requesting a list of IDs of PID tables,
• deliver the list to the companion device,
• wherein the first request is made based on the first UPnP action having the protocol version information as an input argument and the list as an output argument, and
• receive a second request including the ID of the PDI table thereby requesting the PDI table, and
• deliver the PDI table having the ID to the companion device,
• wherein the second request is made based on the second UPnP action having the ID as an input argument and the PDI table as an output argument.
