1 Introduction to the DTS Audio Format Several major consumer audio formats that exist today are listed in this table: Note 1 - All formats require decoders, except Stereo and THX. THX is not a processing system but an audio/video quality control approval system. Its certification stamp means that t...

3 Why won’t my older DVD player play DTS DVDs? The DVD DTS flag was not established until Nov 1998. This flag must beinserted into the DVD’s digital coax or optical output for the receiver torecognize and decode DTS. Therefore DVD units that are not marked“DTS ready” will not play DTS even though th...
