DTS - Referred to as DTS Encore (though DTS themselves don't seem to use that name anymore), this sound format is another familiar holdover from standard DVD. Blu-ray, however, more ably supports the codec at its higher 1.5 Mb/s bit rate. All Blu-ray disc players are required to support the transmission of a DTS bitstream over a digital connection and internal decoding up to at least 2 channels. Most players (other than early models such as the Samsung BD-P1000) will decode internally to 5.1.
