This paper proposes a real-time transferring method of captured video stream to existing handphones without downloading additional software. For real-time transferring of captured vid대 data to handphones, two methods, the WAP based pull-method and the WAP based push-method, are proposed in the paper. Also for transcoding of captured frame into a WBMP image, a threshold setting method which uses the average value of total values of pixels in a scene is proposed. The methods we proposed are implemented in stream engines as video transcoding filter(called WBMPFilter) and video transferring medium(called WirelessMedium). And the experimental system shows 1 frame per 3 seconds transfer of video to existing handphones.
