    PCM pulse coded modulation

    What the heck is that?

    A friend of mine asked me about it and I could not answer him.

    I have two different sound settings on my DVD player

    Dolby Digital/PCM

    PCM

    Technically, PCM is a type of audio encoding format, just like Dolby Digital or DTS. In the case of your DVD player, it is able to pass the dolby digital signal as a PCM compatible datastream in case your receiver does not have the ability to decode DD, but is able to handle PCM.

    PCM is essentially a digital audio "language". Just like DD is a language, and DTS is a language and SDDS and MP3 and whatever else.

    In the case of your DVD player, it can be set to pass the dd dignal as 2 channel data compatible with a PCM decoder.

    For ref, PCM is the format used for digitally passing CD audio. PCM is often used in conjnction with Uncompressed digital audio.
