    History (taken from Wikipedia):

    Introduced in 1999, Digital8 (or D8) is a form of the industry standard DV codec, recorded on Hi8 media. In engineering terms, Digital8 and MiniDV are indistinguishable at the logical format level. To store the digitally encoded audio/video on a standard NTSC Video8 cassette, the tape must be run at double the Hi8 speed. Thus, a 120-minute NTSC Hi8 tape yields 60 minutes of Digital8 video. Most Digital8 units offer an LP mode, which increases the recording time on an NTSC P6-120 tape to 90 minutes.

    For PAL, the Digital8 recorder runs 1½ times faster; thus, a 90-minute PAL Hi8 tape yields 60 minutes of Digital8 video. PAL LP mode returns the tape speed to the Hi8 SP speed, so a Hi8 90-minute tape yields 90 minutes of Digital8 video.

    Sony has licensed Digital8 technology to at least one other firm (Hitachi), which marketed a few models for a while; but as of October 2005 only Sony sells Digital8 consumer equipment. Digital8's main rival is the consumer MiniDV format, which uses narrower tape and a correspondingly smaller cassette shell. Since both technologies share the same logical audio/video format, Digital8 can theoretically equal MiniDV or even DVCAM in A/V performance. But as of 2005, Digital8 has been relegated to the entry-level camcorder market, where price, not performance, is the driving factor. Meanwhile, MiniDV is the de facto standard of the domestic digital tape camcorder market.

    Digital8 recordings are not interchangeable with analog recordings, although many models of Digital8 equipment are able to play Hi8/Video8 analog recordings.
