Here, the channel information may include at least one of a channel number and a channel name.

In step 415, the terminal 110 determines whether a channel information access command is input (or received) from an external controller.

If no channel information access command has been input (or received), the process waits at step 415.

However, if a channel information access command is input (or received), in step 420, the terminal 110 generates an FQDN using the channel information for the broadcast channel.

Since the method for generating the FQDN is the same as described above, a separate description will be omitted.

Here, before generating the FQDN using the channel information, the terminal 110 may determine whether there is previously stored access information corresponding to the broadcast channel according to the corresponding access command. If there is previously stored access information, the terminal 110 may omit the process of generating the FQDN using the channel information.

That is, as described above, when obtaining the access information through the domain name server 130, if the access information is valid using the valid period information acquired together, the terminal 110 is previously stored (that is, the domain name server 130). It can be connected to the service providing server 140 by using the access information) planned through).

In step 425, the terminal 110 requests the domain name server 130 for a connection information query including the generated FQDN.
