Good start: https://en.wikipedia.org/wiki/LaserDisc#AudioDTS is stored on the digital tracks and outputs via coax/toslink as is. AC3RF is stored on the right analog track and outputs on the AC3RF dedicated plug. This is analog. To turn it into digital signal, it requires an AC3RF demodulator (analog in -> digital out). Julien

DTS and AC-3(Dolby Digital) are just different codecs for the audio signal, like MP3 or AAC. DTS supports higher bitrates than AC-3, 1234 kbits vs 640. For DTS you only need a Receiver or TV capable of DTS, and I guess in the last 15 years every Receiver Model does.
They both exist today aswell and you can find both on Blu-Ray, just with much higher bitrates, and fancier names than on LD.(DTS Master Audio and Dolby True HD or the newest: DTS:X and Dolby Atmos, wich both are object based instead of cannel based).
Nowadays I don't think you could hear the diffrence, but on LD DTS should sound better, because of the higher bitrate.
