음성신호 처리부(40)는 방송신호 수신부(10)에서 분리된 음성신호를 스피커를 통해 출력 가능한 신호(R/L)로 처리하여 출력하고,출력단에 앰프를 구비한다.앰프는 제어부(112)로부터 출력되는 음량 조정 신호에 의해 증폭 조정 되게 하여 가청음으로 증폭 시킨다.음성신호 처리부(40) 후단에는 음성신호 출력부(50)가 있어서 음성신호 처리부(40)에서 분리된 음성신호를 스피커를 통해 출력 가능한 신호(R/L)로 변환하여 출력 하는 역할을 수행한다.The voice signal processor 40 processes and outputs the voice signal separated by the broadcast signal receiver 10 into a signal R / L that can be output through a speaker, and includes an amplifier at the output terminal. The amplification is adjusted by the output volume control signal and amplified by an audible sound. A voice signal output unit 50 is provided at the rear end of the voice signal processor 40 to output the voice signal separated by the voice signal processor 40 through the speaker.

디지털방송의 송출은 데이터열(data stream )로 구성된다.데이터를 일정 단위(예:packet)로 코드를 붙여서 그 코드에 의하여 데이터열을 분할 하여 송출하고,The transmission of digital broadcasting is composed of a data stream. The data is coded in a certain unit (e.g., a packet), and the data stream is divided and transmitted by the code.
예;데이터를 채널r의 ①영상②음성③보조신호(재해경보방송신호) ①영상②음성③보조신호(재해경보방송신호) 채널s의 ①영상②음성③보조신호(재해경보방송신호) ①영상②음성③보조신호(재해경보방송신호)…등으로 송출하고,Example: ① Video ② audio ③ auxiliary signal (disaster alarm broadcast signal) of channel r ① Video ② audio ③ auxiliary signal (disaster alarm broadcast signal) ① Video ② voice ③ auxiliary signal (disaster alarm broadcast signal) ① of channel Video ② Audio ③ Auxiliary Signal (Disaster Alert Broadcast Signal). To the back,
어떤 채널(채널r)을 시청중에 다른 채널(채널s)에서 재해경보 방송을 하는 경우에도,방송국에서 채널코드를 r에서 s로 바꾸어 송출함으로 경보방송 시청이 가능하다. 즉,방송국에서 필요시 채널을 바꾸는 효과가 있다.이런 디지털방송의 특성 외에는 아나로그의 경우와 유사하다.Even if a disaster alarm is broadcasted in another channel (channels) while watching a channel (channel r), it is possible to watch the alarm broadcast by changing the channel code from r to s. In other words, the channel has the effect of changing the channel if necessary. Similar to analog, except for the characteristics of digital broadcasting.
도5에서,방송신호 수신부(300)는 튜너와 IF 처리부를 포함한다.수신부(300)에서 튜너는 안테나를 통해 수신되는 디지털방송 신호를 입력하여,제어부(112)의 제어에 따라,채널처리부(310)에서 채널을 선국 하고 선국에 따른 IF신호를 베이스밴드 신호로 변환하여 출력한다.In FIG. 5, the broadcast signal receiver 300 includes a tuner and an IF processor. In the receiver 300, the tuner inputs a digital broadcast signal received through an antenna, and under the control of the controller 112, a channel processor ( In step 310, the channel is tuned and the IF signal according to the tune is converted into a baseband signal and output.
채널처리부(310)는 IF처리부에서 출력되는 베이스밴드신호를 채널 복호화하여 데이터 비트열을 재생한다.The channel processor 310 reproduces the data bit stream by channel decoding the baseband signal output from the IF processor.
TS디코더(신호/data분리 및 처리부)(111)는 채널 처리부(310)에 의해 재생된 데이터 비트열로부터,음성데이터와 영상데이터및 보조데이터를 분리 출력하는 역활을 한다.음성데이터는 엠펙2 음성디코더(360)에서 규격에 따라 디코딩된후 앰프(370)에서 증폭되어 출력된다.The TS decoder (signal / data separation and processing unit) 111 functions to separately output audio data, video data and auxiliary data from the data bit string reproduced by the channel processing unit 310. The audio data is MPEG-2 audio. The decoder 360 is decoded according to a standard and then amplified and output from the amplifier 370.
영상데이터는 엠펙2 영상디코더(330)에서, 규격에 따라 디코딩되고 OSG(on screen graphic)믹서(340) 에서,제어부(112)의 제어에 따라 발생하는 OSG데이터와 합쳐져 영상 처리된후 영상출력부(350)를 통해 화면상에 출력된다.OSG데이터는 제어부(112)가 화면상에 각종정보를 그래픽이나 텍스트로 디스플레이 하기 위한 데이터이다.The image data is decoded in accordance with the standard in the MPEG2 image decoder 330, and in the OSG (on screen graphic) mixer 340, is combined with the OSG data generated under the control of the control unit 112, and then the image output unit. The OSG data is data for the controller 112 to display various types of information on the screen in graphic or text.
TS디코더(111)에서 분리된 보조 데이터는 제어부(112)로 인가 된다.이런 보조 데이터에 ,재경보방송을 위한 제어정보 코드들을 포함할 수 있다.제어부(112)는 stb시스템의 동작을 제어하고,재해경보방송 제어정보 중 시작정보/지역정보/송출시각정보 등의 검출시 시스템전원을 on 시키거나 동작모드를 stb시청모드로 전환하여,경보방송의 방송신호가 AV출력되도록 시스템을 제어한다.재해경보 데이터 저장부(90)는 제어프로그램 데이터와 시스템 제어동작시 발생하는 데이터를 일시저장 하는 역활을 한다.The auxiliary data separated from the TS decoder 111 is applied to the control unit 112. The auxiliary data may include control information codes for re-alarm broadcasting. The control unit 112 controls the operation of the stb system. In case of detecting start information / region information / transmission time information among disaster alarm broadcasting control information, the system is turned on or the operation mode is switched to stb viewing mode to control the system so that the broadcasting signal of alarm broadcasting is outputted. The disaster alarm data storage unit 90 serves to temporarily store the control program data and the data generated during the system control operation.
대기 상태에서,제어부(112)는 TS디코더(111)를 통하여 재해경보방송 시작data가 검출되면, 시각정보/지역정보 등의 일치여부를 검사하고, 일치하면 제어부(112)는 전원 대기상태인 시스템 각부에 전원이 공급되도록 stb전원을 on 시키고,음량 레벨이 상향되도록 음량조절 신호를 출력 한다.In the standby state, when the disaster alarm broadcasting start data is detected through the TS decoder 111, the controller 112 checks whether the time information / region information is matched, and if it matches, the controller 112 is in a power standby state. Turn on the stb power so that the power is supplied to each part, and output the volume control signal to raise the volume level.
TS디코더(111)에서 분리 되어 제어부(112)로 입력된 경보방송 자막데이터 정보는 OSG데이터 형태로 출력되어 OSG믹서(340)로 입력되어 영상 출력부 (350)로 출력된다.The alarm broadcasting subtitle data information separated from the TS decoder 111 and input to the control unit 112 is output in the form of OSG data, input to the OSG mixer 340, and output to the image output unit 350.
도6에서;디지털 stb(튜너2개)In Figure 6; digital stb (two tuners)
수신부2(410)를 통해 재해경보방송 시작data의 검출이있고,시각 정보와 일치하고,지역정보가 일치할 경우 제어부(112)는 시스템전원을 on시키고,방송신호 수신부2(410)를 통해 수신되는 방송 신호가 AV출력 되도록 엠펙 음성 디코더와 영상디코더(360,330)를 제어한다.방송신호 수신부2(410)를 통해 수신된 재해경보방송의 자막데이터는 OSG 믹서(340)에서 방송신호와 믹싱되어 출력한다.If there is a detection of the disaster alarm broadcasting start data through the receiver 2 (410), coincides with the time information, and the area information is matched, the controller 112 turns on the system power and receives it through the broadcast signal receiver 2 (410). The MPEG audio decoder and the video decoders 360 and 330 are controlled to output an AV signal. The caption data of the disaster alarm broadcast received through the broadcast signal receiver 2 410 is mixed with the broadcast signal by the OSG mixer 340 and output. do.
외부입력으로 입력되는 영상을 시청중에도,아나로그 에서와같은 방법으로 ,stb 시청모드로 전환되어 재해경보방송을 AV 출력할수있다.While watching the video input from the external input, you can switch to the stb viewing mode in the same way as in the analog, and output the disaster alarm broadcasting.
여가지 경우를 예시적으로 설명 하였다.Several cases are described by way of example.
수신기를 구성하는 거의 모든 부품이 디지털 stb(d-stb) 또는 컬러stb에 이미 내외장 되어 있어 소프트웨어 변경으로 구현 할 수 있는 것이 특징 이다.따라서 비용이 적게 소요 되고, 구현이 간단한 것이 특징이다.Almost all the parts that make up the receiver are already embedded in the digital stb (d-stb) or color stb and can be implemented by software change, so it is low cost and simple to implement.
