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 contents of a broadcast program and displays the contents on a portion of a TV or an audio radio, and the commercial is automatically tuned to a channel on which a user desired program is broadcast or inserted in the middle of recording a long program. Detection of TV / radio program content and automatic selection of desired channels, making them unsuitable for the management of broadcast channels, the economical use of tapes, and the reduction of modern entropy (unstable behavior, dialogue and information instability). Tape management circuitry during tuning and VCR recording.
일반적으로 방송국에서 발사되는 방송수신기(TV, 라디오등)의 안테나(ANT)에서 수신되는 신호는 제 5 도와 같이 수신된다.In general, a signal received from an antenna ANT of a broadcast receiver (TV, radio, etc.) emitted from a broadcasting station is received with a fifth degree.
즉, 일 수평구간마다 한 번씩 수평동기 신호가 발생하고, 수행동기 신호를 중심으로 칼라버스트 신호와 영상신호(색신호+휘도신호)가 차례로 발생하여 수신됨이 반복된다. 여기서 칼라버스트 신호는 칼라신호 정보를 갖고 있다.That is, the horizontal synchronization signal is generated once every horizontal section, and the color burst signal and the image signal (color signal + luminance signal) are generated and received in sequence with respect to the performance synchronization signal. Here, the color burst signal has 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. 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.In this way, each broadcast station (channel) has the same format of the broadcast signal received by the antenna, and broadcast frequencies, color signals, and luminance signals are received differently according to channels (broadcast stations). After all, since the broadcasting frequency is different for each channel, if the user selects the desired channel (broadcasting station), only the broadcasting frequency of the selected channel is selectively received, and the abs and amplification and signal processing are displayed on the screen. You can watch or listen.
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, in the conventional broadcasting system, there is a concern that a user may miss a better content of another channel when watching or listening to one channel fixedly, and the user has to turn the channels around to avoid unpleasant broadcasting. In the case of recording a long program such as a movie, an advertisement inserted in the middle could not be avoided, so there were many problems in managing or recording a channel.
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 present invention has been made in view of the above-mentioned drawbacks, and the program contents of the broadcasting station are detected by its characteristics, and the channel is automatically tuned by the signals memorized by priorities according to the user's preferences. The purpose of this is to stop recording or resume recording of the VCR tape when the signal is input, and to detect the broadcast program and automatically tune to the channel with the desired program.
이하에서 이와 같은 목적을 달성하기 위한 본 발명의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention for achieving such an object will be described in detail with reference to the accompanying drawings.
먼저, 본 발명을 설명하기 위해서는 몇가지 전제조건이 필요하다.First, some prerequisites are needed to describe the present invention.
첫째, 각 방송국에서 방송신호를 발사할 때 기존의 포맷과 다르게 발사되어야 한다. 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.First, when firing a broadcast signal from each broadcasting station must be fired differently from the existing format. That is, there is a horizontal synchronization signal generated by each broadcasting station and received by the antenna of the receiver every horizontal section as shown in FIG. 6, and the color burst signal, which is the next color information signal, is centered on the horizontal synchronization signal. The broadcast signal is used so that the pilot signal and the video signal (color signal + luminance signal) are sequentially located.
둘째, 이와 같은 포맷을 갖는 방송신호의 주파수는 각 채널(방송국)마다 다르게 방송하지만, 파이럿트 신호는 방송내용 정보신호로써, 각 채널마다 공통으로 일정기준을 갖도록 방송한다.Second, although the frequency of a broadcast signal having such a format is broadcast differently for each channel (broadcasting station), the pilot signal is a broadcast content information signal, and broadcasts to have a predetermined standard in common 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. 현재, 유럽의 방송방식은 파이럿트 신호를 실어서 방송하고 있다고 알고 있다.For example, about 1 MHz for movie content, about 2 2 MHz for show, about 2 MHz for news, and about 2.5 MHz for drama. It should be loaded so that the contents of broadcasting can be discriminated. Currently, European broadcast systems are known to carry pilot signals.
상기와 같은 두가지의 전제조건(각 채널마다 방송주파수는 다르더라도 방송내용별로 코드화한 파이럿트 신호를 실어서 방송함)으로 각 방송국에서 방송한다고 가정하고 본 발명을 설명하면 다음과 같다.The present invention will be described below on the assumption that broadcasting is performed by each broadcasting station under the two preconditions (the pilot signal encoded by the broadcasting contents is broadcast even though the broadcasting frequency is different for each channel).
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 신호를 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.1 is an overall block diagram according to the present invention, which receives broadcast station radio waves through an antenna and detects each program content by characteristics (eg, movie, news, drama, show, advertisement…) by a pilot signal. Priority of each program based on the channel signal detection unit 1 for applying radio waves to the high frequency amplification circuit of the
단, TV(7)와 VCR(8)은 통상의 구성이므로 설명을 생략한다. 이와 같이 구성된 본 발명은 예를들어 [표 1]과 같은 프로그램에 의해 설명하면 다음과 같다.However, since the
[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.As shown in [Table 1], if a program is currently broadcasted and propagated by a pilot signal as shown in FIG. 6 in the broadcasting station of each channel, the channel signal detection unit 1 broadcasts the contents for each channel as shown in [Table 1]. Detect it together.
그리고, 프로그램 특성 메모리부(2)에는 사용자가 정한 튜닝 우선순위가 [표 2]에서와 같이 있다고 가정하자.In the program
[표 2]TABLE 2
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 the
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, when the first part of the movie is started and the advertisement is started, the pilot signal is not the movie but the frequency of the advertisement, so the channel signal detection unit 1 detects it and the TV is automatically tuned to channel 4 so that the viewer can see the show. And when
그리고 채널 2의 영화가 완전히 끝나게 되면 프로그램 특성 메모리부(2)의 우선순위에 의해 채널을 다시 채널 4로 자동튜닝되어 쇼유가 화면에 나타나게 된다. 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.When the movie of
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.2 is a diagram illustrating the operation of the TV set of the system according to the present invention, and shows the initial situation (a) (b) stored in the program
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(S1∼S5).3 and 4 are operation flowcharts of the system according to the present invention. First, when viewing with the 3rd diagram, the power supply is always checked and the program characteristics of all channels are continuously checked. The contents of the channel are displayed by LEDs (Light Emitting Diodes), and the programs are displayed on the screen in order (S 1 to S 5 ).
또한, 현재 프로그램을 계속 시청하다가 현재 프로그램이 끝나면 다음 순번 프로그램으로 자동 전환되고 이를 화면에 디스플레이시킨다(S6~S11).In addition, while continuing to watch the current program after the current program is automatically switched to the next sequence program is displayed 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(S1∼S4), 다시 상기 내용이 나오면 이어서 녹화한다(S5∼S9).Unlike the above, when recording as shown in FIG. 4, if the advertisement comes out while recording the desired contents, the recording is stopped (video motor or tape stop) (S 1 to S 4 ), and the above contents are recorded again afterwards (S 5 to S). 9 ).
상기에서는 TV와 VCR의 경우만을 설명했는데 이는 음향기기에도 폭넓게 적용할 수 있게 된다.In the above, only the case of TV and VCR has been described, which can be widely applied to sound equipment.
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, in the TV / radio broadcasting program detection and channel selection automatic tuning and VCR recording according to the present invention, as described above, the tape management circuit detects the program contents of broadcasting stations by their characteristics and stores the signals stored in the rank according to the user's taste. Auto-tuning channels by VCR, and when recording with VCR, control recording stops or resumes recording of VCR tape when other signals are input, efficient channel management and entropy of users who live in high entropy society like modern times It lowers the cost and has a great effect on the economic use of the tape.
