R:right) without using actual rear speakers. TVS was developed by Sony to produce surround sound for home use using just a stereo TV.
This only works when playing a multichannel Dolby audio sound track. Furthermore, if the player is set up to output the signal from the DIGITAL OUT (OPTICAL or COAXIAL)/ HDMI OUT jack, the surround effect will only be heard when “DOLBY DIGITAL” is set to
