본 발명은 방송 프로그램의 내용을 검출하여 TV나 오디오 라디오의 어느 일부분에 그 내용을 디스플레이하고, 사용자가 원하는 프로그램이 방송되고 있는 채널로 자동튜닝되거나 긴 프로그램의 녹화시 중간에 삽입되는 광고방송등은 녹화되지 않게 하여 방송채널의 관리나 녹화테이프의 경제적인 이용 및 현대의 엔트로피(불필요한 동작이나 대화 및 정보로 인한 불안정도)를 감소시키는데 적당하도록한 TV/라디오의 프로그램 내용의 검출 및 원하는 채널의 자동튜닝과 VCR 녹화시 테이프 관리회로에 관한 것이다. The present invention detects the content of the broadcast program and displays the information in any portion of a TV or audio radio, the user is inserted into the medium during recording of the auto-tuning or longer program in the channel containing the desired program is being broadcast commercials, etc. automatic detection and desired channels do not record the broadcast economical entropy of use and modern management and the recording tape of the channel (unwanted behavior or conversation and information instability caused by) the reduction was to be suitable TV / radio sikineunde program content when tuning the VCR record relates to a tape management circuit.

일반적으로 방송국에서 발사되는 방송수신기(TV, 라디오등)의 안테나(ANT)에서 수신되는 신호는 제 5 도와 같이 수신된다. Signal received at the antenna (ANT) of the general broadcast is launched from the station receiver (TV, radio, etc.) are received as the fifth help.

즉, 일 수평구간마다 한 번씩 수평동기 신호가 발생하고, 수행동기 신호를 중심으로 칼라버스트 신호와 영상신호(색신호+휘도신호)가 차례로 발생하여 수신됨이 반복된다. That is, one with horizontal and a horizontal synchronizing signal generated once for each period, and mainly performs the synchronization signal and the color burst signal to the video signal (color signal + luminance signal) occurs, then the search is repeated reception. 여기서 칼라버스트 신호는 칼라신호 정보를 갖고 있다. The color burst signal has the color signal information.

이와 같이 각 방송국(채널)마다 안테나에 수신되는 방송신호의 포맷이 동일하고, 단지 채널(방송국)에 따라 방송주파수 및 색신호와 휘도신호가 서로 다르게 수신된다. Thus, the same format of the broadcast signal received at the antenna for each broadcast station (channel), and is only different from each other the receiving station, and a color signal and a luminance signal according to a channel (station). 결국, 채널별로 방송주파수가 다르기 때문에, 사용자가 원하는 채널(방송국)을 선택하면 선택된 채널의 방송주파수만 선택적으로 수신되고 복근 및 증폭, 신호처리되어 화면상에 디스플레이 되므로 사용자가 원하는 TV 또는 라디오방송을 시청 또는 청취할 수 있다. After all, because of the different broadcast frequencies for each channel, when the user selects a desired channel (broadcast station), only the broadcast frequency of the selected channel is selectively received and processed abs and amplifying a signal to so displayed on the screen, the user wants a TV or radio broadcast You may be watching or listening.

그러나 이와 같은 종래의 방송시스템에 있어서는 사용자가 어느 한 채널을 고정시켜 시청하거나 청취시 다른 채널의 더 좋은 내용을 놓칠 염려가 있었으며 또한, 사용자가 싫은 방송을 피하기 위해 채널을 이러저리 돌려야만 하는불편이 있었고, 영화와 같이 긴 프로그램의 녹화시 중간에 삽입되는 광고 등을 피할 수 없으므로 채널의 관리나 녹화시 많은 문제점이있었다. However, these in the conventional broadcasting system had the user viewed by fixing the one-channel or miss the better information of the other channel listening experience addition, the inconvenience that only the user and turn the channel these away to avoid unpleasant broadcast was, can not be avoided, such as ads that are inserted in the middle when recording a long program, there were a lot of problems when recording or management of the channel, such as a movie.

본 발명은 이와 같은 종래의 결점을 감안하여 안출한 것으로 방송국의 프로그램 내용을 그 특성별로 검출하여 사용자의 취향에 따라 우선순위별로 메모리된 신호에 의해 채널을 자동튜닝 되도록 하며 동시에 VCR로 녹화시 다른 특성의 신호가 입력될 때 VCR의 테이프를 제어녹화 정지 또는 녹화재개하고, 방송 프로그램을 검출하여 원하는 프로그램이 있는 채널로 자동튜닝 되도록 하는데 그 목적이 있다. The invention such as one made in view to solve the prior art shortcomings by detecting the program information of the broadcasting station by the characteristics and to automatically tune to a channel by a signal memory by priority according to the user's preference at the same time while recording different attributes to VCR to resume control of the record stop or record a tape in VCR when a signal is input, it detects the broadcast program it is an object to be automatically tuned to the channel containing the desired program.

이하에서 이와 같은 목적을 달성하기 위한 본 발명의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다. Described in detail by the accompanying drawings, an embodiment of the present invention to achieve such a purpose hereinafter follows.

먼저, 본 발명을 설명하기 위해서는 몇가지 전제조건이 필요하다. First, a few prerequisites are necessary to describe the present invention.

첫째, 각 방송국에서 방송신호를 발사할 때 기존의 포맷과 다르게 발사되어야 한다. First, when firing a broadcasting signal from each broadcasting station to be fired different from the conventional format. 즉, 각 방송국에서 발사되어 수신기의 안테나에 수신되는 방송신호가 제 6 도와 같이 일 수평구간마다 발생되는 수평동기 신호가 있고, 이와 같은 수평동기 신호를 중심으로 다음에 색정보신호인 칼라버스트 신호와 파이럿트(pilot)신호, 그리고 영상신호(색신호+휘도신호)가 차례로 위치함이 반복되도록 방송신호를 구사한다. That is, the horizontal synchronization signal is a broadcast signal received at the antenna of the emission the receiver at each station is generated for each horizontal period day as the sixth assist, and this is then the color information signals in the center of the horizontal synchronizing signal color burst signal and pilot bit (pilot) signal, and to speak a broadcast signal to be repeated also in turn positions the video signal (color signal + the luminance signal).

둘째, 이와 같은 포맷을 갖는 방송신호의 주파수는 각 채널(방송국)마다 다르게 방송하지만, 파이럿트 신호는 방송내용 정보신호로써, 각 채널마다 공통으로 일정기준을 갖도록 방송한다. Second, this frequency of the broadcast signal having the same format is broadcast so as to have a predetermined reference in common as the broadcast information, the information signal of each channel broadcast differently (station), but the pilot bit signal, for each channel.

예를 들면 방송내용이 영화류인 경우는 1MHz를 2개 정도, 쇼유(show)류인 경우는 1.5MHz를 2개 정도, 뉴스(news)류인 경우는 2MHz 2개 정도, 드라마류인 경우는 2.5MHz를 2개 정도 실어서 방송내용을 판별할 수 있도록 한다. For example, if the film is broadcast content when a giant amphipods 1MHz 2 or so, syoyu (show) giant amphipods case about 2 to 1.5MHz, news (news) giant amphipods case 2MHz 2 or so, Drama giant amphipods are 2 to 2.5MHz Come or so rooms so that you can determine the broadcast content. 현재, 유럽의 방송방식은 파이럿트 신호를 실어서 방송하고 있다고 알고 있다. Currently, the broadcasting system in Europe knows that the broadcast Come run the pilot bit signal.

상기와 같은 두가지의 전제조건(각 채널마다 방송주파수는 다르더라도 방송내용별로 코드화한 파이럿트 신호를 실어서 방송함)으로 각 방송국에서 방송한다고 가정하고 본 발명을 설명하면 다음과 같다. When describing the present invention, assuming that the broadcast in each broadcasting station in two preconditions (also come on, even if each channel, the broadcast frequency is different from the real one pilot bit signal by encoding the broadcast information broadcast), such as the following:

제 1 도는 본 발명에 따른 전체 블록구성도로서, 방송국 전파들을 안테나를 통해 받아 각 프로그램 내용을 파이럿트 신호에 의해 특성별(예 : 영화, 뉴스, 드라마, 쇼우, 광고…,)로 검출하며 상기 전파를 TV(7)의 고주파 증폭회로에 인가하는 채널 신호 검출부(1)와, 상기 채널 신호 검출부(1)의 특성별 신호를 받아 이미 사용자의 취향에 따라 메모리된 내용에 의하여 각 프로그램의 우선순위를 결정하는 프로그램 특성 메모리부(2)와, 상기 채널 신호 검출부(1)와 프로그램 특성 메모리부(2)의 신호를 받아 디스플레이부(4)가 우선순위에 따라 프로그램을 시각적으로 나타내도록 디스플레이부(4)에 신호를 인가하며 제일 우선할 수 있는 외부신호(리모콘)를 받아 프로그램 특성 메모리부(2)에 인가하는 채널 디스플레이부(3)와, 상기 프로그램 특성 메모리부(2)의 First turn as an overall block diagram of the present invention, receives the broadcast station radio waves through the antenna, each program information the pilot bit-specific characteristics by signal (such as movies, news, drama, Shoichi, c ...,) is detected in, and the propagating the TV channel signal detector (1) for applying a high-frequency amplifier circuit 7, a first of the channel signal receiving characteristic by the signal of the detector (1) already each program by the memory contents according to the user's preference priority program attribute that determines the memory section (2), the channel signal detecting unit 1 and the program attribute memory section 2, a display to visually indicate to the program according to the priority display unit 4 receives a signal unit ( 4) applying a signal to and receives a first outer signal (remote control) that can be characteristic of the program channel to be applied to the display memory unit (2) section 3 and the program attribute memory section (2) 호를 받아 우선순위별로 튜닝하여 TV(7)의 국부발진기에 신호를 인가하는 자동튜닝부(5)와, 녹화시 상기 프로그램 특성 메모리부(2)의 신호를 받아 사용자가 선택한 한 종류의 프로그램만 녹화하도록 VCR(8)의 모터구동부를 제어하는 VCR 녹화제어부(6)로 구성된다. Receiving a call priority tuning by position and automatically tuning to apply a signal to the local oscillator of the TV (7) section 5, and a recording when only one type of program selected by the user is receiving a signal from the program attribute memory section (2) to record it consists of a VCR recording control unit 6 for controlling the motor driving of the VCR (8).

단, TV(7)와 VCR(8)은 통상의 구성이므로 설명을 생략한다. However, TV (7) and a VCR (8) is omitted here because it is a conventional configuration. 이와 같이 구성된 본 발명은 예를들어 [표 1]과 같은 프로그램에 의해 설명하면 다음과 같다. The present invention constructed as described above, for example, is described by as shown in [Table 1] Program follows.

[표 1] TABLE 1

[표 1]과 같이 현재 각 채널의 방송국에서 프로그램이 제 6 도와 같이 파이럿트 신호가 실려서 각각 방송, 전파되고 있다고 하면 채널신호 검출부(1)에서 각 채널별로 방송되고 있는 내용을 [표 1]과 같이 검출해낸다. [Table 1] and the like are the pilot bit signal from a broadcast station program as a sixth assist in each channel then placed each broadcast is that propagates the information that is being broadcast in each channel in the channel signal detector (1) [Table 1] recall detection steps.

그리고, 프로그램 특성 메모리부(2)에는 사용자가 정한 튜닝 우선순위가 [표 2]에서와 같이 있다고 가정하자. And, assume that the program attribute memory section (2), the tuning priorities set by the user, as shown in Table 2.

[표 2] TABLE 2

Figure kpo00002

상기와 같은 상태에서 TV(7)을 온(ON)시키면 TV(7)는 각 부(1∼5)에 의해 채널 2를 먼저 선택하여 시청자가 영화를 볼 수 있게 된다. When in a state as described above on the TV (7) (ON) TV (7) is so viewers can watch a movie by selecting the channel 2 by the respective sections (1-5) first.

그러다가 이 영화의 1부가 끝나고 광고를 시작하게 되면 파이럿트 신호가 영화류가 아니고 광고류의 주파수를 싣고 있으므로 이를 채널신호 검출부(1)가 감지하여 TV는 채널 4로 자동튜닝 조절되어 시청자가 쇼우를 보게 되고, 채널 2의 광고가 끝나 영화 2부가 시작될 때에는 채널 4는 채널 2로 다시 자동튜닝되어 영화를 볼 수 있게 된다. Then add one of the film ends and when the start advertising pilot bit signal is not so loaded the frequency of the ad stream a movie stream by detecting the this channel signal detecting unit (1) TV is automatically tuned controlled by channel 4 for the viewer Shaw watch and, when the two ends of the channel ad film started two additional channel 4 is automatically re-tune to channel 2 is able to see the movie.

그리고 채널 2의 영화가 완전히 끝나게 되면 프로그램 특성 메모리부(2)의 우선순위에 의해 채널을 다시 채널 4로 자동튜닝되어 쇼유가 화면에 나타나게 된다. And when the film of the channel 2 is completely ended automatically tune to a channel by the priority of the program attribute memory section (2) again to the channel 4 is displayed on the screen show oil. 그리고 만약, 사용자가 영화를 녹화하도록 하였을때, 파이럿트 신호가 영화류가 아니면 녹화하지 않도록 하므로 영화녹화중 광고가 시작되어 채널 4로 옮겨져 쇼우가 시청되더라도 쇼우는 녹화가 되지 않도록 했다가 채널 2의 영화로 다시 튜닝되면 녹화를 재개한다. And if you were not to the user when to record movies, pilot bit signal is therefore not to record or movie Ryu started advertising in movie recording moved to Channel 4, even if Shaw is watching Shaw is not recorded in channel 2 After re-tuning the movie will resume recording.

제 2 도는 본 발명에 따른 시스템의 TV 세트운영 동작설명도를 나타낸 것으로, 프로그램 특성 메모리부(2)에 메모리되어 있는 초기 상황(가)(나)과 현재 방송국에서 방송되고 있는 상황(다)을 나타내고 있으며 이에 따른 TV의 외형도를 (라) 나타내고 있다. A second turning the initial situation (A) (B) to the situation that is being broadcast at the current station (C), which shows an explanatory diagram of the system TV set operating behavior, the memory in the program attribute memory section (2) according to the invention It represents and shows the external view of the TV accordingly (d).

제 3 도와 제 4 도는 본 발명에 따른 시스템의 동작순서도로서, 먼저 제 3 도와 같이 시청시, 항상 공급되는 전원을 받아 전 채널의 프로그램 특성을 계속 체크하다거 TV 서브전원 공급으로 TV가 구동되면 전 채널의 내용을 LED(Light Emitting Dioded)로 디스플레이하는 동시에 우선 순서대로 프로그램을 화면에 디스플레이 시킨다(S 1 ∼S 5 ). Third help fourth When turning the TV is powered by the a flow chart of the system according to the invention, when the first viewer as a third tile, always supply still check is going TV sub power supply receiving power to a program characteristic of all the channels that are around the the contents of the channel at the same time displaying a LED (Light Emitting Dioded) first, in order thereby display the program on the screen (S 1 ~S 5).

또한, 현재 프로그램을 계속 시청하다가 현재 프로그램이 끝나면 다음 순번 프로그램으로 자동 전환되고 이를 화면에 디스플레이시킨다(S 6 ~S 11 ). Further, while still viewing the current program, then the end of the current program will automatically switch to the next program sequence and display them on the screen (S 6 ~ S 11).

상기와 달리 제 4 도와 같이 녹화시, 원하는 내용을 녹화도중 광고가 나오면 녹화를 정지(비디오 모터나 테이프 정지)시키고(S 1 ∼S 4 ), 다시 상기 내용이 나오면 이어서 녹화한다(S 5 ∼S 9 ). When recording, as the fourth help Unlike the above, it comes out that during the advertising record the desired information is stopped (the motor or a video tape stop) recording (S 1 ~S 4), the information is recorded and then comes out again (S 5 ~S 9).

상기에서는 TV와 VCR의 경우만을 설명했는데 이는 음향기기에도 폭넓게 적용할 수 있게 된다. In the above it has been described only the case of the TV and VCR which is able to apply broadly in the sound system.

따라서 본 발명에 따른 TV/라디오의 방송 프로그램 검출 및 채널선택 자동튜닝과 VCR 녹화시 테이프 관리회로는 이상의 설명에서와 같이 방송국의 프로그램 내용을 그 특성별로 검출하여 사용자의 취향에 따라 순위별로 메모리된 신호에 의해 채널을 자동튜닝 되도록 하며, 또한 VCR로 녹화할시에는 다른 특성의 신호가 입력될 때 VCR 테이프를 콘트롤 녹화정지 또는 녹화재개하며, 효율적인 채널관리와 현대같이 엔트로피가 높은 사회에 사는 사용자들의 엔트로피를 낮춰주며 녹화테이프의 경제적 이용에 큰 효과를 갖게 된다. Therefore, TV / radio broadcasting program detecting and channel selection automatic tuning and VCR recording, when tape management circuit detects by the characteristics of the program information of the broadcasting station as in the above description, a signal memory for each ranked according to the user's taste according to the invention and to automatically tune to a channel by, also, the entropy of the user living in a high entropy society the VCR tape, and resumes control record stop or record, as an efficient channel management and modern time the signal of other characteristic input during recording to the VCR It gives the lower will have a large effect on the economic use of the recording tape.
