HDV (High-Definition Video)
HDV is an inexpensive high-definition video recording format which uses MPEG2 compression to fit HD content onto the same DV or MiniDV tapes originally developed for standard definition recording. The compression used results in some quality compromises compared to higher bandwidth HD recording formats, but has still proved useful for many purposes including several popular TV shows.
DVCAM (Digital Video Camera)
DVCAM is Sony's proprietary extension of the DV format and is designed for professional use. Panasonic's own solution is the DVCPRO. DVCAM equipment is more rugged than DV cameras as it is used in news filming and on-the-road recording. They also record to a (slightly) higher quality than DV.
A DVCAM camcorder will take standard DV tape but because of it is wider track pitch and faster tape speeds. DVCAM tape travels at 28.193mm/second in NTSC/60Hz (DV is 18.182) or 28.221 mm/sec in PAL/50Hz (DV is 18.831). You will typically get only about 65% of the normal storage capacity (i.e. a 60 min tape will give you up to 40 minutes). DVCAM tapes however are available for up to 3 hours of recording on the standard (large) size. A mini DVCAM cassette records up to 40 minutes.
