ABSTRACT
The two-channel, video-tape medium that makes use of specially encoded signals to carry the audio part of a video program. The Beta hi-fi version developed by Sony used the video heads on the VCR’s rotating tape drum. The VHS hi-fi system developed by JVC has separate audio heads, also on the tape drum, in addition to the video heads. Hi-fi video sound, which must make use of Dolby matrixing if it is to deliver surround sound, is not as capable as current digital systems, particularly the 5.1-channel versions. Nonetheless, it does have impressive performance, and it is more than able to handle the dynamics and clarity requirements of all but the most demanding matrixed-surround motion picture material.
