TV셋트(20)는 도 3a에 보여진 바와 같은 데이타포맷 즉, 셋탑박스(10)의 고유어드레스(SETTOP ADDR), 명령(COMMAND), 그리고 자신의 고유어드레스(TV-SET ADDR)를 실은 무선신호를 발생한다. 셋탑박스(10)는 도 3b에 보여진 바와 같은 데이타포맷 즉, 다수의 TV셋트중 신호를 송신하고자 하는 TV셋트의 고유어드레스(TV-SET ADDR), TV셋트의 명령에 해당하는 데이타(DATA), 그리고 자신의 고유어드레스(SETTOP ADDR)를 실은 무선신호를 발생한다. 즉, 사용자가 현재 시청채널을 변경하고자 할 경우 리모콘등의 미도시된 키입력부를 조작하면, 그에 대응하는 키입력을 받는 TV셋트(20)의 신호처리부(21)는 무선신호발생부(22)를 제어하여 도 3a에 보여진 바와 같은 포맷의 무선신호를 발생한다. 무선신호발생부(22)는 셋탑박스(10)의 고유어드레스 (SETTOP ADDR)와 변경할 채널 및 이를 요구하는 명령(COMMAND), 그리고 자신의 고유어드레스(TV-SET ADDR)를 무선신호로 발생하여 셋탑박스(10)에 채널변경을 요구한다. 셋탑박스(10)의 무선신호수신부(14)는 TV셋트(20)에서 발생되는 무선신호를 수신받아 신호처리부(12)로 출력한다. 신호처리부(12)는 수신된 무선신호를 해독하여 자신의 고유어드레스를 확인한 후, TV셋트(20)에서 요구한 명령에 따라 동작한다. 신호처리부(12)는 TV셋트(20)에서 채널변경을 요구했으면, 방송수신부(11)의 현재 채널을 요구한 채널로 변경시킨다. 방송수신부(11)는 신호처리부(12)에 의해 변경된 채널의 방송신호를 수신하여 신호처리부(12)로 출력한다. 신호처리부(12)는 변경된 채널로부터 수신된 방송신호를 비디오, 오디오, 및 기타데이타로 각각 신호처리한 후 무선신호발생부(13)를 제어하여 무선신호내에 실려있는 TV셋트의 고유어드레스(TV-SET ADDR)를 가진 TV셋트로 송신되도록 한다. 무선신호발생부(13)는 신호처리된 방송신호가 다수의 TV셋트중 채널변경을 요구한 TV셋트(20)로만 보내지도록 도 3b에 보여진 바와 같은 포맷의 무선신호를 발생시킨다. TV셋트(20)의 무선신호수신부(23)는 셋탑박스(10)에서 발생되는 무선신호를 수신받아 신호처리부(21)로 출력한다. 신호처리부(21)는 수신된 무선신호를 해독하여 자신의 고유어드레스를 확인한 후, 데이타를 신호처리하여 시청가능토록 한다.When one set top box (STB) supports a plurality of TV sets, various signals are transmitted and received wirelessly. To this end, the TV sets and the set-top box each have a unique address and mutually generate a radio signal having a data format as shown in Figs. 3A-3B. It is transmitted and received without regard to position and direction within a predetermined distance. The TV set 20 transmits a radio signal carrying a data format as shown in FIG. 3A, that is, a unique address (SETTOP ADDR), a command (COMMAND), and its own unique address (TV-SET ADDR) of the set-top box 10. Occurs. The set-top box 10 has a data format as shown in FIG. 3B, that is, a unique address (TV-SET ADDR) of a TV set to transmit a signal among a plurality of TV sets, data DATA corresponding to a command of the TV set, And it generates a radio signal carrying its own address (SETTOP ADDR). That is, when the user wants to change the current viewing channel, if the user manipulates a key input unit, such as a remote controller, the signal processor 21 of the TV set 20 that receives the corresponding key input is the wireless signal generator 22. To generate a radio signal having a format as shown in FIG. 3A. The wireless signal generator 22 generates the set-top box 10 with a unique address (SETTOP ADDR), a channel to change, a command for requesting the command (COMMAND), and its own address (TV-SET ADDR) as a wireless signal. Box 10 is requested to change channels. The wireless signal receiver 14 of the set-top box 10 receives a wireless signal generated from the TV set 20 and outputs it to the signal processor 12. The signal processor 12 decodes the received radio signal, checks its own address, and operates according to the command requested by the TV set 20. When the TV set 20 requests the channel change, the signal processor 12 changes the current channel of the broadcast receiver 11 to the requested channel. The broadcast receiver 11 receives a broadcast signal of a channel changed by the signal processor 12 and outputs the broadcast signal to the signal processor 12. The signal processing unit 12 processes the broadcast signal received from the changed channel into video, audio, and other data, respectively, and then controls the radio signal generator 13 to control the unique address of the TV set loaded in the radio signal. To the TV set with SET ADDR). The radio signal generator 13 generates a radio signal of the format as shown in FIG. 3B so that the signal-processed broadcast signal is sent only to the TV set 20 which requests channel change among the plurality of TV sets. The wireless signal receiver 23 of the TV set 20 receives a wireless signal generated from the set top box 10 and outputs the signal to the signal processor 21. The signal processor 21 decodes the received radio signal to confirm its own address, and then processes the data to allow viewing.

상술한 바와 같이, 본 발명의 무선연결 가능한 셋탑장치는, 셋탑박스와 TV셋트내에 무선송수신부를 마련하여 각종 신호를 무선으로 송수신할 수 있도록 하므로써 TV셋트와 셋탑박스 사이의 복잡한 선연결을 없애 장소의 제약을 받지 않고 사용자가 편리하게 사용할 수 있도록 한다.As described above, the wirelessly connectable set-top device of the present invention eliminates the complicated line connection between the TV set and the set-top box by providing a wireless transmitter / receiver in the set-top box and the TV set to transmit and receive various signals wirelessly. Make it convenient for users without being restricted.
