- Panasonic has come out with the D-3 format, using 1/4" tape. The camcorders
- and decks are $100k plus. Not exactly viable in the home market.

- You have to keep in mind that DAT is in the 45kHz area (sampling rate). Video
- requires a bandwidth of at least 20 MHz. The numbers are probably wrong, but
- the idea here is that it takes MANY more bits to record a piece of video than
- it does to record two channels of audio. Also keep in mind that the D- formats
- also record four channels of audio, digitially.
-
- It is just too expensive for the home market.
