When video first became available to the masses there were a few formats vying for prominance.

VHS (Not great quality)
Betamax ( better quality, but for the betacams the video was rused pass the recording head by about 7 times the normal speed to increase resolution)

V2000 (excellent quality), but no one wanted these as they were more expensive to produce.

Umatic high band was broadcast quality video equipment.
These were not used in anyway for home use. They were only used by professional film and television companies.
