At this time, the set-top box 30 and the terminal 50 are connected to the session in a state capable of short-range communication.

First, when the broadcast content server 21 transmits specific broadcast content to the copy server 23 in step S61, the copy server 23 stores the received broadcast content in step S63. In this case, the specific broadcast content transmitted to the copy server 23 may be a broadcast content having a relatively high request frequency or broadcast content that is expected from a client from among broadcast contents stored in the broadcast content server 21.

Next, in step S65, the terminal 50 requests the broadcast content to be viewed by the set-top box 30 according to the terminal user's selection signal. In step S67, the set-top box 30 transmits a request for broadcast content received from the terminal 50 to the copy server 23 through the network 10.

Next, in step S69, the replica server 23 transmits the broadcast content requested by the terminal 50 to the set-top box 30 through the network 10. In step S71, the set-top box 30 transmits the received broadcast content to the terminal 50 through the short range communication unit 39. In step S73, the terminal 50 plays the received broadcast content.

In step S75, the set-top box 30 determines whether a predetermined time has elapsed without changing a channel after transmitting the broadcast content to the terminal 50 in step S71. That is, the set top box 30 determines whether the same broadcast content is being transmitted to the terminal 50 for a predetermined time. In this case, the predetermined time may be set to determine a time when the terminal user selects a broadcast channel and starts to continuously watch the broadcast content through the selected broadcast channel. The predetermined time may be set in the set top box 30 by default, or may be set by receiving a selection signal of a terminal user. At this time, the predetermined time may be set to a time between 10 seconds and 300 seconds.

As a result of the determination in step S75, when a predetermined time has elapsed, in step S77, the set-top box 30 transmits the broadcast content information being played in the terminal 40 to the IPTV 40 through the IPTV connection unit 37.

In step S79, the IPTV 40 displays the received broadcast content information in an information display window. Accordingly, the IPTV user may acquire the broadcast content information being played in the terminal 50 through the information display window displayed on the screen. At this time, the IPTV 40 may display an information display window on a predetermined area of the screen.

When the information display window is selected in step S81, the IPTV 40 requests the set-top box 30 to transmit the broadcast content being played in the terminal 50 in step S83. In step S85, the set-top box 30 transmits the requested broadcast content to the IPTV 40.

At this time, the terminal 50 requests transmission of broadcast content to the set-top box 30 using short-range communication.

Next, in step S103, the set-top box 30 determines whether a channel change request is received from the terminal 50. When the channel change request is received as a result of the determination in step S103, the set-top box 30 performs a step S101. If it is determined in step S103 that the channel change request has not been received, in step S105, the set-top box 30 determines again whether a predetermined time has elapsed. In this case, the predetermined time may be a time between 10 seconds and 300 seconds.

If the predetermined time has not elapsed as a result of the step S105, the set-top box 30 performs the step S103. If a predetermined time elapses as a result of the determination in step S105, the set-top box 30 transmits the broadcast content information to the IPTV 40 in step S105.

Next, in step S109, the set-top box 30 determines whether the broadcast content information transmission period has been reached. If it is determined in step S109 that the transmission period has not been reached, the set-top box 30 determines again whether a channel change request is received from the terminal 50 in step S111. If the channel change request is not received as a result of the determination in step S111, the set-top box 30 performs a step S109. When the channel change request is received as a result of the determination in step S111, the set-top box 30 performs a step S101.

When the determination result of step S109 becomes a transmission time, the set top box 30 retransmits the broadcast content information to the IPTV 40 in step S113.

Meanwhile, in the present embodiment, the set-top box 30 discloses an example of transmitting broadcast content information of the broadcast content being played in the terminal 50 to the IPTV 40 regardless of the broadcast content being played in the IPTV 40.
