본 발명은 차세대 이동통신인 IMT-2000(International Mobile Telecommunication in the year 2000, 범세계 이동통신) 시스템의 텔레비전 수신장치에 관한 것으로, 특히 IMT-2000 기지국의 TV 송신 기능과 IMT-2000 단말기의 TV 수신기능이 가능하도록 하여 IMT-2000 단말기에서 TV를 수신하기에 적당하도록 한 IMT-2000 시스템의 텔레비전 수신장치에 관한 것이다.The present invention relates to a television receiver of an IMT-2000 (International Mobile Telecommunication in the year 2000) system, which is a next generation mobile communication, and in particular, a TV transmission function of an IMT-2000 base station and a TV reception of an IMT-2000 terminal. The present invention relates to a television receiver of an IMT-2000 system that enables a function to be suitable for receiving a TV from an IMT-2000 terminal.

일반적으로 IMT-2000은 ITU-R의 TG/1에서 권고안을 작성하고 있는 제3세대 이동통신시스템(Third Generation Mobile System, TGMS)이다. 이 시스템은 이동사용자의 요구에 따라 PSTN/ISDN/B-ISDN 등과 같은 고정통신망에 의해 지원되는 다양한 통신서비스에 하나 또는 그 이상의 무선 링크를 사용하여 접속하도록 하는 이동통신 시스템이다. 사용주파수 대역은 WARC-92에서 결정된 1885MHz ~ 2025MHz와 2110MHz ~ 2200MHz로서, 기존의 다양한 통신시스템에 의해 제공되던 서비스를 제공할 뿐만 아니라, 보다 향상된 기술에 의한 한차원 높은 서비스도 제공할 수 있는 차세대 이동통신시스템이다. 이 시스템에서는 지상망 또는 위성망에 연결될 수 있는 다양한 형태의 이동전화기가 이동통신용 또는 고정통신용으로 사용될 수 있다.In general, IMT-2000 is a third generation mobile system (TGMS) that makes recommendations in ITU-R's TG / 1. This system is a mobile communication system that allows one or more radio links to connect to various communication services supported by a fixed communication network such as PSTN / ISDN / B-ISDN according to the mobile user's request. The frequency bands used are 1885MHz ~ 2025MHz and 2110MHz ~ 2200MHz, which are determined by WARC-92, and not only provide the services provided by various existing communication systems, but also provide the next generation of mobile communication using advanced technology. System. In this system, various types of mobile telephones that can be connected to terrestrial or satellite networks can be used for mobile or fixed communications.

한편 종래의 이동통신 단말기들은 동화상 기능이 없고, 문자표시와 음성만을 들을 수 있을 뿐이다. 따라서 이동통신 서비스회사에 의해서 각종 정보를 문자를 통하여 LCD 화면으로 볼 수 있고, 단말기에 FM 라디오 수신기능이 있어 라디오를 들을 수 있으며, 또한 통신회사의 사설 방송국에 의해 송신되는 정보를 듣고 문자정보를 볼 수가 있다.Meanwhile, the conventional mobile communication terminals do not have a moving picture function and can only hear text display and voice. Therefore, various information can be viewed on the LCD screen by the mobile communication service company, and the terminal has FM radio reception function so that the user can listen to the radio. I can see it.

도1은 종래 이동통신 시스템의 블록구성도이다.1 is a block diagram of a conventional mobile communication system.

이에 도시된 바와 같이, 이동통신 서비스를 제공하는 이동통신서비스 회사의 사설 방송국(1)과; 상기 사설 방송국(1)과 연결되어 CDMA(Code Division Multiple Access) 기지국 기능을 수행하는 CDMA 기지국(2)과; 상기 CDMA 기지국(2)과 무선으로 연결되어 이동통신 서비스를 사용하는 CDMA 단말기(3)로 구성된다.As shown therein, a private broadcasting station 1 of a mobile communication service company providing a mobile communication service; A CDMA base station 2 connected to the private broadcasting station 1 to perform a code division multiple access (CDMA) base station function; The CDMA base station 2 is connected to the CDMA base station 2 wirelessly and uses a mobile communication service.

이와 같이 구성된 종래 이동통신 시스템의 동작을 설명하면 다음과 같다.The operation of the conventional mobile communication system configured as described above is as follows.

먼저, 이동통신서비스회사의 사설 방송국(1)에서 주식시세나 주요 뉴스 등을 내보내면 단말기(3)를 보유하고 있는 사용자가 그러한 정보를 이용하려 할 때, 단말기(3)에서 설정을 하면, 단말기(3)의 LCD 화면에 계속 표시가 되고, 음성신호인 경우 리시버를 통하여 들을 수 있다.First, when the stock market or the main news is sent out from the private broadcasting station 1 of the mobile communication service company, when the user having the terminal 3 tries to use such information, the terminal 3 makes a setting. The LCD screen of (3) continues to be displayed, and the voice signal can be heard through the receiver.

또한 FM 라디오 수신기능은 단말기에 라디오 튜너를 내장하여 이동 중이거나 정지 중에 일반적인 라디오와 똑같이 들을 수가 있다.In addition, the FM radio receiver has a built-in radio tuner in the handset, so you can listen to it as you would a normal radio on the go.

그러나 이러한 종래의 이동통신 시스템은 문자정보와 음성정보를 보거나 들을 수 있는 기능만 있기 때문에, 화상을 볼 수는 없었다. 즉, 라디오 이후 TV가 나왔으며, 전화기 이후 화상전화기가 발명되었듯이 사람들은 눈으로 보는 것을 꾸준히 연구하고 있으며, IMT-2000에서 화상 전송이 필요한 것도 이러한 사람들의 끊임없는 욕구에서인데, 이러한 화상 전송의 기능을 가진 IMT-2000 기능에서 단지 상대방의 얼굴만 보고 전화하는 기능만을 수행하는 것 보다는 이러한 화상을 볼 수 있는 기능이 추가되는 것이 필요하게 되었다.However, such a conventional mobile communication system has only a function of viewing or listening to text information and voice information, and thus cannot view images. That is, after radio, TV came out, and after telephone, video telephone was invented, people are continually researching what they see. In the function of IMT-2000 with functions, it is necessary to add the function to view these images rather than just to look at the other party's face.

이에 본 발명은 상기와 같은 종래의 제반 문제점을 해소하기 위해 제안된 것으로, 본 발명의 목적은 IMT-2000 기지국의 TV 송신 기능과 IMT-2000 단말기의 TV 수신기능이 가능하도록 하여 IMT-2000 단말기에서 TV를 수신할 수 있는 IMT-2000 시스템의 텔레비전 수신장치를 제공하는 데 있다.Accordingly, the present invention has been proposed to solve the above-mentioned general problems, and an object of the present invention is to enable the TV transmission function of the IMT-2000 base station and the TV reception function of the IMT-2000 terminal.

상기에서 IMT-2000 단말기(30)는, 상기 이동통신 서비스부(20)에서 무선으로 송출된 고주파를 수신하여 기저대역 주파수로 변환시키는 RF 처리부(31)와; 상기 RF 처리부(32)에서 출력되는 TV 신호를 원래의 영상신호와 음성신호로 신장시키는 영상/음성신호 처리부(32)와; 상기 영상/음성신호 처리부(32)에서 신장된 영상신호는 액정화면에 표시하고, 음성신호는 스피커로 출력하는 출력부(33)로 구성된다.The IMT-2000 terminal 30 includes: an RF processor 31 which receives a high frequency wirelessly transmitted from the mobile communication service unit 20 and converts it into a baseband frequency; A video / audio signal processor 32 for extending the TV signal output from the RF processor 32 into an original video signal and an audio signal; The video signal extended by the video / audio signal processor 32 is displayed on the LCD screen, and the audio signal is composed of an output unit 33 for outputting to a speaker.

이와 같이 구성된 본 발명에 의한 IMT-2000 시스템의 텔레비전 수신장치의 동작을 첨부한 도면에 의거 상세히 설명하면 다음과 같다.The operation of the television receiver of the IMT-2000 system according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

먼저 TV 방송국(10)에서 방송을 송출하면, 이동통신 서비스회사의 기지국인 이동통신 서비스부(20)에서는 이 신호를 수신받아서 IMT-2000의 통신 규격에 맞는 디지털 신호로 변환한다. 즉, TV 튜너부(21)에서 TV 방송국(10)의 신호를 튜너하면, A/D 변환부(22)에서 튜너된 아날로그 신호를 디지털로 변환시키고, 영상압축/음성압축부(23)에서 영상신호와 음성신호를 압축시키게 된다. 그러면 IMT-2000 프로토콜 변환부(24)에서 압축된 디지털 신호를 IMT-2000의 통신 규격에 맞는 디지털 신호로 변환시키고, 송신부(25)는 IMT-2000 프로토콜의 신호를 무선으로 전송하게 된다.First, when the TV station 10 transmits a broadcast, the mobile communication service unit 20, which is a base station of the mobile communication service company, receives this signal and converts the signal into a digital signal conforming to the communication standard of the IMT-2000. That is, when the TV tuner 21 tunes the signal of the TV station 10, the A / D converter 22 converts the tuned analog signal into digital, and the video compression / audio compression unit 23 The signal and the voice signal are compressed. Then, the IMT-2000 protocol converter 24 converts the compressed digital signal into a digital signal conforming to the IMT-2000 communication standard, and the transmitter 25 transmits the signal of the IMT-2000 protocol wirelessly.

그래서 IMT-2000 단말기(30)에서는 TV를 수신하고 싶을 때에는 TV 모드로 설정하여, 이동 중이거나 차량에서 또는 스포츠 현장에서 해설자의 해설을 듣고 보면서 실제 현장에서 감할 수 있게 된다. 즉, RF 처리부(31)에서는 이동통신 서비스부(20)의 송신부(25)에서 무선으로 송출된 신호를 입력받아 처리하고, 영상/음성신호 처리부(32)에서 압축된 영상/음성신호를 신장시켜, 출력부(33)를 통해 액정 디스플레이나 스피커로 출력하게 된다.Thus, when IMT-2000 terminal 30 wants to receive a TV, the TV mode can be set, so that while listening to the commentator's commentary while moving or in a vehicle or a sports scene, the actual scene can be subtracted. That is, the RF processor 31 receives and processes the signal transmitted wirelessly from the transmitter 25 of the mobile communication service unit 20, and expands the compressed video / audio signal from the video / audio signal processor 32. Then, the output unit 33 is output to the liquid crystal display or the speaker.

이러한 기능을 수행하기 위해서는 기지국인 이동통신 서비스부(20)에서는 방송신호를 IMT-2000 프로토콜에 맞게 변환하는 장치가 필요하게 되고, 단말기(30)에서는 기지국(20)으로부터 수신되어 들어오는 TV 화상 신호를 액정화면에 표시하고, TV 음성신호는 스피커로 나오게 한다.In order to perform such a function, a mobile communication service unit 20, which is a base station, needs an apparatus for converting a broadcast signal according to the IMT-2000 protocol, and the terminal 30 receives a TV image signal received from the base station 20. It is displayed on the LCD screen and the TV audio signal is output to the speaker.

이러한 본 발명의 동작을 다시 한번 설명하면 다음과 같다.Referring again to the operation of the present invention as follows.

도2에서와 같이, TV 방송국(10)에서 방송신호를 송출한다.As shown in Fig. 2, the TV broadcasting station 10 transmits a broadcast signal.

이 신호는 이동통신 서비스회사의 TV 튜너(21)에 입력되어 TV 방송을 수신한다. A/D 변환부(22)에서는 TV 튜너(21)에서 수신된 TV 수신신호를 디지털 신호로 변환되도록 하고, 신호의 영상과 음성 신호가 압축되어 IMT-2000 프로토콜에 맞는 신호로 변환된다.This signal is input to the TV tuner 21 of the mobile communication service company to receive a TV broadcast. The A / D converter 22 converts the TV received signal received by the TV tuner 21 into a digital signal, and the video and audio signals of the signal are compressed and converted into a signal conforming to the IMT-2000 protocol.

이러한 기저대역 주파수의 신호는 기지국(20)의 송신부(25)에 있는 안테나를 통하여 송출된다.This baseband frequency signal is transmitted through an antenna in the transmitter 25 of the base station 20.

그러면 IMT-2000 단말기(30)에서는 RF 처리부(31)에서 고주파를 수신하여 기저대역 주파수로 변환시키고, 베이스밴드 칩(Baseband Chip)인 영상/음성신호 처리부(32)에서 원래의 TV 신호로 복원하고, 음성신호는 스피커로 나오며, 화상신호는 액정화면에 표시하게 된다.Then, the IMT-2000 terminal 30 receives the high frequency from the RF processor 31, converts the signal into a baseband frequency, and restores the original TV signal from the video / audio signal processor 32, which is a baseband chip. The audio signal is output to the speaker, and the image signal is displayed on the LCD screen.

이처럼 본 발명은 IMT-2000 기지국의 TV 송신 기능과 IMT-2000 단말기의 TV 수신기능이 가능하도록 하여 IMT-2000 단말기에서 TV를 수신하게 되는 것이다.As such, the present invention enables the TV transmission function of the IMT-2000 base station and the TV reception function of the IMT-2000 terminal to receive the TV from the IMT-2000 terminal.

이상에서 본 발명의 바람직한 실시예를 설명하였으나, 본 발명은 다양한 변화와 변경 및 균등물을 사용할 수 있다. 본 발명은 상기 실시예를 적절히 변형하여 동일하게 응용할 수 있음이 명확하다. 따라서 상기 기재 내용은 하기 특허청구범위의 한계에 의해 정해지는 본 발명의 범위를 한정하는 것이 아니다.Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

이상에서 살펴본 바와 같이, 본 발명에 의한 IMT-2000 시스템의 텔레비전 수신장치는 이동 중이거나 차량에서 IMT-2000 단말기를 통해 TV 정보를 얻을 수 있으며 또한 스포츠 현장에서 해설자의 해설을 듣고 보면서 실제 현장을 감상하는 등 IMT-2000 단말기를 통해 TV를 수신할 수 있는 효과가 있게 된다.As described above, the television receiver of the IMT-2000 system according to the present invention can obtain TV information through the IMT-2000 terminal while moving or in a vehicle, and can also watch the actual scene while listening to the commentary of the commentator in the sports scene. The TV can be received through the IMT-2000 terminal.
