상기에서 상술한 종래의 수상기장치에 있어서는 일단 지나간 텔레비젼 수신영상 및 음성신호가 재현할 수 없게 되어 있다.In the above-described conventional receiver apparatus, the television received video and audio signal once passed cannot be reproduced.
그러므로 연속해서 화면을 내보내야 하는 방송의 특징으로 인하여 순간적으로 놓친 경우나 화면을 다시보고자 할 때 이를 실현하는데 문제점이 있었다.Therefore, there is a problem in realizing this in case of missed moment or when you want to see the screen again due to the characteristic of broadcasting that must send the screen continuously.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로써, 본 발명의 목적은 수신된 텔레비젼 신호를 스크린상에 보여주는 것과 동시에 메모리에도 일시 저장하여 시청자가 순간적으로 놓친 화면을 다시볼 수 있도록 하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to display a received television signal on the screen and also to temporarily store it in a memory so that the viewer can see the screen missed momentarily. have.
상기 목적을 달성하기 위한 본 발명 텔레비젼 수상기장치는 제2도에 도시된 바와 같이 튜너부(21), 영상 중간주파증폭처리부(22), 음성 중간주파증폭처리부(23), 영상신호발생부(24), 음성검파부(25), 압축저장부(28), A/D 변환기(29), 압축회로부(30), 메모리부(31), 메모리 제어부(32), 압축신호 복원부(33), D/A 변환기(34), 영상증폭부(26), 음성증폭부(27), 브라운관, 스피커로 구성된다.The television receiver of the present invention for achieving the above object has a tuner section 21, an image intermediate frequency amplifier processing section 22, an audio intermediate frequency amplifier processing section 23, and an image signal generating section 24 as shown in FIG. ), Voice detection unit 25, compression storage unit 28, A / D converter 29, compression circuit unit 30, memory unit 31, memory control unit 32, compressed signal recovery unit 33, D / A converter 34, video amplifier 26, audio amplifier 27, CRT, speaker.
상기와 같이 구성된 본 발명의 수상기장치는 텔레비젼 안테나를 통하여 수신된 방송신호를 선국 처리하는 튜너부(21)는 중간주파수 처리된 신호를 영상 및 음성 중간주파증폭처리부(22)(23)로 공급되어 상기 영상 및 음성 중간주파증폭처리부(22)(23)에서 처리된 신호에 따라 신호를 출력한다.In the receiver apparatus of the present invention configured as described above, the tuner unit 21 for tuning the broadcast signal received through the television antenna is supplied to the video and audio intermediate frequency amplification processing units 22 and 23. The video and audio intermediate frequency amplifiers 22 and 23 output signals according to the signals processed.
상기 영상 중간주파증폭처리부(22)에서 출력된 신호는 영상신호발생부(24)로 공급되고, 상기 음성 중간주파증폭처리부(23)에서 출력된 신호는 음성 검파부(25)로 공급된다.The signal output from the image intermediate frequency amplifier processor 22 is supplied to the image signal generator 24, and the signal output from the voice intermediate frequency amplifier processor 23 is supplied to the voice detector 25.
상기 영상신호발생부(24)솨 음성검파부(25)에서 출력된 영상 및 음성신호를 압축하여 저장하는 압축저장부(28)와 상기 영상신호발생부(24)와 음성 검파부(25)에서 또는 압축저장부(28)에서 저장된 영상 및 음성신호를 각각 선택적으로 출력하기 위한 스위칭부(a, b, c)(a', b', c')가 있다.The video signal generator 24 compresses and stores the video and audio signals output from the voice detector 25, and the video signal generator 24 and the voice detector 25. Alternatively, there is a switching unit (a, b, c) (a ', b', c ') for selectively outputting the video and audio signals stored in the compression storage unit 28, respectively.
상기 압축저장부(28)에서는 상기 영상신호발생부(24) 및 음성검파부(25)에서 출력되는 영상 및 음성신호를 디지털신호로 변화하는 A/D 변환기(29)로 보낸다.The compression storage unit 28 transmits the video and audio signals output from the video signal generator 24 and the audio detector 25 to the A / D converter 29 which converts the digital signals into digital signals.
상기 A/D 변환기(29)는 아날로그 형태의 신호를 디지털 형태의 신호로 바꾸어 디지털 신호를 압축회로부(30)로 출력한다.The A / D converter 29 converts an analog signal into a digital signal and outputs the digital signal to the compression circuit unit 30.
상기 A/D 변환기(29)에서 출력된 디지털 신호는 방대한 양의 데이터이다.The digital signal output from the A / D converter 29 is a huge amount of data.
상기 압축회로부(30)는 상기 방대한 양의 데이터를 MPEG-2 압축기법을 이용하여 정보량을 축소키킴으로써 메모리부(31)의 용량 부담을 줄여준다.The compression circuit unit 30 reduces the amount of information of the memory unit 31 by reducing the amount of information by using the MPEG-2 compressor method.
상기 압축회로부(30)를 거친 신호는 메모리부(31)에 저장된다.The signal passed through the compression circuit unit 30 is stored in the memory unit 31.

The compression signal restorer 33 restores the signal.
상기 압축신호복원부(33)에서 복원된 신호는 D/A 변환기(34)로 공급되어 디지털 형태의 신호를 아날로그 형태의 신호로 바꾸어준다.The signal recovered by the compressed signal restorer 33 is supplied to the D / A converter 34 to convert a digital signal into an analog signal.
상기 D/A 변환기(34)에서 변환된 신호는 상기 스위칭부(a, b, c)(a',b ,c')를 통해 영상증폭부(26)와 음성증폭부(27)를 통하여 영상신호는 브라운관으로, 음성신호는 스피커로 공급되어 상기 메모리부(31)에 저장된 신호를 재구현시킬 수 있다.The signal converted by the D / A converter 34 receives an image through the image amplifier 26 and the audio amplifier 27 through the switching units a, b, and c (a ', b, c'). The signal is supplied to the CRT, and the audio signal is supplied to the speaker to reimplement the signal stored in the memory unit 31.
이때 메모리부(31)의 데이터신호를 디스플레이하는 동안 현재 인테나로부터 수신되는 신호를 메모리부(31)로 보낼 필요가 없을 경우에는 현재 수신되는 신호의 A와 ac 및 a'c' 의 진행을 막고 B의 신호만을 be와 b'c' 로 보낸다.At this time, if it is not necessary to send the signal received from the current antenna to the memory unit 31 while displaying the data signal of the memory unit 31, the process of A, ac and a'c 'of the currently received signal is prevented and B Only signals to be and b'c 'are sent.
또한 본 발명의 구성에서 메모리부(31)에 또 하나의 메모리 2를 추가하여 메모리부(31)의 데이터 신호를 계속 화면에 디스플레이하고 있는 동안에도 수신되는 신호 A를 메모리 2에 저장할 수가 있다.In addition, in the configuration of the present invention, another memory 2 may be added to the memory unit 31 to store the received signal A in the memory 2 while the data signal of the memory unit 31 is continuously displayed on the screen.
상기에서 설명한 바와 같이 본 발명의 화면기억장치를 내장한 텔레비젼에 있어서는 다음과 같은 효과가 있다.As described above, the television having the screen storage device of the present invention has the following effects.
영상 및 음성신호를 압축저정부에 저장함으로써 시청자가 순간적으로 놓친 화면이나 음성 및 다시 확인하고 싶은 장면들을 쉽게 재현할 수가 있다.By storing the video and audio signals in the compression storage, it is easy to reproduce the screens, audios, and scenes that the viewer misses momentarily.
따라서 정지화면도 구현할 수 있으며, 화면확대도 가능하다.Therefore, it is possible to implement still images and to enlarge the screen.
