LOCAL AREA IMAGE TRANSMISSION SYSTEM USING MULTI-DROP NETWORK AND METHOD THEREOF

摘要

PURPOSE: A method of transmitting a near video using a multi-drop network is provided to connect to many cameras with one cheap transmission line by using the multi-drop network, thereby transmitting video data transmitted from each camera. CONSTITUTION: A video data collection processor confirms whether video data is obtained from a camera unit(S310). If so, the camera unit responds to 'Yes'(S320). The video data collection processor transmits a signal for transmitting the obtained video data(S330). The camera unit transmits compressed coding video data to the video data collection processor(S340). The camera unit transmits a transmission completion message of the video data(S350). The video data collection processor transmits a receiving message to the camera unit(S360). The video data collection processor multiplexes the received video data with video information, and stores the multiplexed data and the information, then transmits the data with the information to an external network(S370).
