Abstract
본 발명은 녹화 및 재생이 가능한 임의의 영상/음성재생기기에서 재생된 재생신호가 다른 영상/음성재생기기로의 무선전송이 가능하도록 된 재생신호 무선전송장치를 제공하기 위한 것이다.An object of the present invention is to provide a playback signal wireless transmission apparatus in which a playback signal reproduced in an arbitrary video / audio playback device capable of recording and playback can be wirelessly transmitted to another video / audio playback device.
이를 위한 본 발명은, 정보기록매체에 기록된 영상/름성정보를 각각 영상신호 및 음성신호로 재생가능할 뿐 만 아니라 임의의 채널의 방송프로그램을 정보기록매체에 녹화할 수 있는 영상/음성재생기기에서, 상기 영상/음성신호를 복합영상신호로 변환시키는 RF모듈레이터(1)와, 상기 RF모듈레이터(1)로부터의 복합영상신호를 수신안테나(34)를 갖춘 다른 영상/음성재생기기의 특정주파수대역으로 전송하는 복합영상신호송신수단(2)으로 구성되고, 상기 RF모듈레이터(1)는 상기 영상/음성신호의 변조에 필요한 소정의 변조주파수를 발생시키는 변조주파수발생부(22)와, 상기 변조주파수발생부(22)로부터의 변조주파수를 기초로 상기 영상신호 및 음성신호를 변조하는 영상/음성신호변조부(24), 상기 변조된 영상신호와 음성신호의 혼합시 소정의 동기신호를 제공하는 동기 신호발생부(26) 및, 상기 동기신호발생부(26)로부터의 동기신호를 기초로 상기 영상/음성신호변조부(24)에서 출력되는 변조신호를 복합영상신호화하는 혼합부(28)로 구성되며, 상기 복합영상신호송신수단(2)은 상기 혼합부(28)로부터의 복합영상신호를 소정치 증폭시키는 RF증폭부(30)와, 상기 RF증폭부(30)에서 증폭 출력되는 복합영상신호를 전송하는 안테나(32)로 구성된 것이다.The present invention for this purpose, in the video / audio reproducing apparatus capable of reproducing the video / voice information recorded on the information recording medium as a video signal and an audio signal, respectively, as well as recording a broadcast program of any channel on the information recording medium. RF modulator (1) for converting the video / audio signal into a composite video signal, and the composite video signal from the RF modulator (1) to a specific frequency band of another video / audio playback device having a receiving antenna (34). A composite video signal transmitting means (2) for transmitting, wherein the RF modulator (1) comprises a modulation frequency generator (22) for generating a predetermined modulation frequency for modulation of the video / audio signal, and the modulation frequency generation A video / audio signal modulator 24 for modulating the video signal and the audio signal based on the modulation frequency from the unit 22, and a predetermined synchronization signal when the modulated video signal and the audio signal are mixed. A mixing unit for converting a modulated signal output from the video / audio signal modulator 24 based on the synchronization signal generator 26 and the synchronization signal generated from the synchronization signal generator 26; 28), wherein the composite video signal transmitting means (2) comprises: an RF amplifier (30) for amplifying the composite video signal from the mixing unit (28) by a predetermined value and an amplified output from the RF amplifier (30). The antenna 32 is configured to transmit a composite video signal.
