Abstract

본 발명은 무선 채널을 통하여 이동하면서 통신하는 셀룰라폰에 관한 것으로, 셀 사이트의 중계를 통한 특정 상대방과의 통화시 통화하고자 하는 상대방의 전화번호를 이용하여 사용자의 영상신호를 부호화 한후 무선채널을 통하여 송수신하며, 수신되는 영상신호에서 사용자 주변에 위치되어 있는 영상 디스플레이장치의 채널을 무선으로 선택하여 수신되는 상대방의 영상을 디스플레이 하도록한 셀룰라폰에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular phone which communicates while moving through a wireless channel. When a call is made with a specific party through a relay of a cell site, a video signal of the user is encoded by using a phone number of the other party to be talked through and then over the wireless channel. The present invention relates to a cellular phone that transmits and receives and wirelessly selects a channel of an image display apparatus located near a user from a received image signal to display an image of a received counterpart.

본 발명은 셀룰라폰에 사용자의 영상을 송수신하는 처리수단을 구비하여 통화로가 형성된 사용자의 영상을 무선음성채널을 통해 송수신하며 수신되는 영상신호에 포함되어 있는 캐리어 신호를 통해 사용자의 주변에 위치되어 있는 영상기기의채널을 원격점유하여 통화하는 상대방 영상을 디스플레이함으로 셀룰라 폰의 중계를 통한 화상통화를 실현하게 되어 통화에 신뢰성 및 영상기기의 채널점유에 편리성이 제공된다.The present invention is provided with a processing means for transmitting and receiving the user's video on the cell phone to transmit and receive the user's video through the wireless audio channel formed on the call channel is located in the vicinity of the user through a carrier signal included in the received video signal By remotely occupying the channel of the video device to display the video of the other party on the call to realize the video call through the relay of the cell phone provides the reliability and convenience in channel occupancy of the video device.
