Claim:
1. An operating method for a broadcast receiving device, comprising: receiving an audio or video, wherein the audio or video is uncompressed and is included in a broadcast stream which is not transmitted through an internet protocol (IP) network; receiving address information based on the audio or video, for obtaining a signaling table via the broadcast stream, wherein the receiving the address information based on the audio or video comprises extracting a signature from frames of the audio and video and receiving the address information based on the signature; and transmitting a request message for the signaling table based on the address information, to a server providing the signaling table; receiving a response including the signaling table based on the request message through the IP network from the server, wherein the request message includes a first query information which includes time information of the request message, and a second query information which designates the signaling table, wherein the first query information further includes a duration term representing a time interval for which the signaling table is being requested by the broadcast receiving device, and a start time term representing a start of the time interval for which the signaling table is being requested by the broadcast receiving device, wherein the second query information further includes a table term representing that the signaling table is being requested by the broadcast receiving device, wherein the signaling table included in the response corresponds to the table term included in the request message, wherein the server transmits the requested signaling table, that is scheduled to take effect during the time interval represented by the duration term, and updates of the requested signaling table, when the request message does not include an update term, and the server transmits only updates of the requested signaling table that are scheduled to take effect during the time interval, when the request message includes the update term,
