TV Virtual Surround (TVS) (page 58)
Technology from Sony developed to produce
surround sound for home use using just a
stereo TV. Designed to work with the sound
characteristics of your TV, this technology
brings the excitement of surround sound to
your home using nothing more than your
stereo TV's internal speakers. Furthermore,
various TVS modes are available. For
example, "TVS WIDE" uses just two
speakers to create a virtual sound
environment that makes you feel like you are
surrounded by multiple speakers.
