The Beta Hi-Fi system used FM subcarriers recorded by the video heads.
Reports in magazines indicate great sound: 20-20000, 80 db dynamic range,
distortion and flutter nil.

Because the sound and video are recorded by the video heads, "dubbing"
where only the audio is replaced is impossible with Beta Hi-Fi, likewise
with the video.  You'd have to make a copy between two VCR's to substitute
either the audio or the video.

The VHS camp is coming out with a similar system, supposedly already available
in Japan.  Standardization of the VHS specs and US availability should happen
in 1984.

There are some subtleties to Beta Hi-Fi; check the recent Audio and/or High
Fidelity issues for more discussion.
