A DISTRIBUTED VIDEO ACQUISITION SYSTEMSong, Jian; Beijing Zoweetech Ltd. (International Foundation for Telemetering, 2017-10)Camera has been used in telemetry system over decades now. Normally, the video signal outputted from cameras would be acquired by video module(s) located in general data acquisition equipment. In this paper, a distributed video acquisition system is presented. It is a synchronous acquisition system consisted of a record and control unit and several video acquisition units. The synchronous shutter control for cameras and data flow synchronous transportation inside the system is added as well. The accuracy of timing and synchronous acquisition of the system is less than 50ns.
