Sony BETACAM SP BVW-22P Operation Manual page 4

The BVW-22P videocassette player is primarily designed for use as an "office viewer."
The unit is so compact that it can also be conveniently used on the road or wherever
ease and simplicity of operation are demanded.
The BVW-22P uses the "Betacam SP" (Superior Performance) format to enhance the
video and audio quality and achieve longer playback time. Connecting the unit to a
video monitor or a conventional TV receiver allows you to readily view either small size
(max. playback time of 36 minutes) or large size (max. playback time of 100 minutes)
cassette-taped video programs. Reproduction of four audio channels (two longitudinal
and two AFM audio channels) is possible.
