Figure 2 is a block diagram showing the configuration of a multifunctional set-top box system according to an embodiment of the present invention. 3 is a block diagram showing the configuration of a terminal 200 in the multi-function set-top box system according to an embodiment of the present invention.

1 to 3, the IP network 1 and the multifunctional set-top box system 2 transmit and receive data in a packet form.

Hereinafter, when transmitting a signal or data from the IP network 1 to the multi-function set-top box system 2 is referred to as 'forward transmission' or 'downward transmission', on the contrary, from the multi-function set-top box system 2 to the IP network 1 When transmitting signals or data, it is called 'reverse transmission' or 'upward transmission'.

The IP network 1 is connected to the multifunctional set-top box system 2 as an IP network providing a unicasting or multicasting routing protocol.

The multi-function set-top box system 2 receives the packet data Data_P through the IP network 1, and transmits the voice packet Data_V and the control signal Cs to the IP network. It may include a set-top device (or set-top box, 100) and the terminal 200.

The set-top device 100 is a device that connects to the TV receiver 3 to use Internet services. Next, the next-generation interactive multimedia communication service such as video on demand (VOD), home shopping, and network game (so-called interactive TV) It is a device having a home communication terminal function necessary to use.

Set-top device 100 according to an embodiment of the present invention is a multi-function integrated set-top device having a set-top box function for IPTV, VoIP phone function and karaoke function. To this end, the set-top device 100 includes a central controller 110, an external interface 120, a VoIP module 140, an IPTV module 150, a karaoke module 160, and a wireless interface 130.

The central controller 110 controls the overall operation of the set-top device 100 by controlling the components of the set-top device 100. In addition, the central controller 110 controls the flow of data and signals transmitted and received between the external interface 120 and the wireless interface 130. In detail, the central control unit 110 inputs the packet data Data_P received from the external interface 120 to the corresponding module among the VoIP module 140, the IPTV module 150, and the karaoke module 160 during downlink transmission. The controller transmits the control signal Cs received from the air interface 130 and transmits the control signal Cs to the IP network 1 through the external interface 120.

The external interface 120 may be formed in a structure connected to the IP network 1 by wire. The external interface 120 delivers packet data (Data_P) including broadcast data transmitted from the IPTV server 5 providing the TV broadcast contents by the structure in which the IP network 1 and the IPTV server 5 are sequentially connected. Receive. In addition, the external interface 120 includes packet data (Data_P) including voice packets transmitted from other Internet telephones by a structure in which the Internet telephone 7 of another Internet telephone user using IP network 1 and VoIP is sequentially connected.
