The MVID-301S module adds one channel of H.264 High Definition (HD) video/audio acquisition capability to Curtiss-Wright’s MEDAU/ MCDAU/MWDAU/MnACQ/MARM airborne data acquisition units. Effective video compression rate varies from 512Kbps to 15 Mbps. Output frame rate can be decimated down to 1 frame per second, and output resolution can be re-sampled to a lower resolution. One mono (low or high level) or one stereo audio channel can be acquired. The compressed video and/or audio are multiplexed into MPEG-2 transport stream. The module also provides time annotation overlay with programmable positioning.
