The MVID-541M module set adds one channel of H.264 High Definition (HD) or Standard Definition (SD) video/audio acquisition capability to Curtiss-Wright’s Miniature Network High-Speed Data Acquisition Unit (MnHSD-2000). The module provides H.264 video compression for any one of the video inputs. Effective video compression rate varies from 512Kbps to 10 Mbps. Input pictures are pre-processed with de-interlacing and adjustment of brightness, contrast, and hue. 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 an MPEG-2 transport stream. The module also provides time annotation overlay with programmable positioning.
