Abstract
본 발명은 부재시에 방문하는 방문객의 영상 및 시간을 압축 부호화하여 메모리에 저장할 수 있도록 한 메모리 내장형 영상전화기에 관한 것으로, 내부 카메라로 부터의 영상신호를 부호화기를 통해 압축 부호화 하여 통신망으로 전송하고, 이 통신망으로 부터 전송되어 오은 영상 데이타신호를 복호화기를 통해 원래의 신호로 복호화 하여 모니터를 통해 디스플레이 하도록 구성된 영상전화기에, 외부로 부터의 초인종 입력신호에 의거하여 외부 카메라로 부터 입력되는 영상신호가 부호화기를 통해 압축부호화 되어 내장된 메모리에 저장되고, 이 메모리에 저장된 압축부호화된 영상데이타가 복호화기를 통해 원래의 신호로 복호화되어 모니터를 통해 디스플레이 되도록 제어하는 수단을 추가하여 구비함으로서, 그 구조가 간단하고 비용이 저렴하며 사용이 편리하 영상 메모리 가능 영상전화기를 실현한 것이다.The present invention relates to a video phone with a built-in memory that can compress and store the video and time of the visitor visiting in the absence of the visit, in the memory, and transmits the video signal from the internal camera through the encoder to the communication network, The video telephone, which is configured to decode the video data signal transmitted from the communication network to the original signal through the decoder, and display it on the monitor, and the video signal input from the external camera is based on the doorbell input signal from the outside. Through the compression-coded and stored in the built-in memory, and by adding a means for controlling the compressed coded image data stored in the memory to be decoded to the original signal by the decoder to be displayed on the monitor, the structure is simple and cost This is cheap and It is easy to use and realizes video memory capable video phone.
