Question: what is the difference between dolby digital and dts?
Answer: Dolby Digital compresses 5.1 digital audio down to a bit rate of 640 kbits/s (kilobits per second) for Blu-ray discs. For DVD discs, it supports a slightly lower bit rate: up to 448 kbits/s. DTS on the other hand, is less compressed and supports higher bit rates of up to 1.5Mb/s (megabits per second).
