HDV(High Definition Video) The high-definition, wide screen version of the DV magnetic tape format. Like DV, HDV recording moves at a constant data rate and stores data on the same DV and MiniDV tapes as SD camcorders. Introduced in 2003, HDV uses 4:2:0 color sampling, MPEG-2 video compression and MPEG-1 audio compression (16-bit stereo). HDV machines record YCbCr frames in 1280x720p, 1980x1080i or 1980x1080p resolutions. See DV and DTV. How to thank TFD for its existence?
