    Do you mean PCM? PCM (Pulse-code modulation) is for all intense purposes at the core of all digital audio. It is the language used to convey digital audio.

    Pulse-code modulation - Wikipedia, the free encyclopedia

    DSP is Digital Sound Processing and refers to the manipulation of digital audio.

    Cinema DSP was born in 1986 and was really achieved in 1988 after Dolby Pro-Logic was released. However Dolby Pro-Logic surround channel provides a poor and weak "spot" of sound since this channel is mono. Therefore you only get a small surround soundfield, actually nothing to see with large movie theaters where many speakers are used at the surround channel. As a result yamaha engineers achieved some enhancements by using A DSP in series with the Dolby Pro-Logic decoder, that is cinema DSP, to create the type of spacious surround heard in the movie theaters. This is a seven or five speakers based system with all digital processing. All channels are stereo but this is not discrete stereo , which means that all signals remain correlated.

    What is Yamaha CINEMA DSP

    5ch or 7ch Stereo is a mode whereby the stereo signal is output via all speakers present. Stereo mode is what it says on the tin and only utilises the front stereo pair. If an audio format has more than just 2 channels then these are mixed down into stereo if using the stereo mode.

    Yes, STRAIGHT would be the most appropriate mode to use in conjunction with the HD formats found on Blu-ray titles.

    DTS NEO:6 is similar to Dolby Pro Logic. Both can either create pseudo surround channels not apparent in the native format or extract matrixed surround channels from stereo formats. Some prefer to use NEO:6 rather than Dolby Pro Logic and it is ultimately a matter of personal preference as to which is better than the other. Both are primarily now used in conjunction with stereo sources in order to create pseudo surround, most notably in conjunction with stereo 2 channel TV broadcasts.

    Tv not hd channel - Dolby Pro Logic or DTS NEO
    Tv hd channel - Standard
    Xbmc - Depends what you are watching/listening to
    When listening to music via music video - 2 ch stereo
    And via iPhone with dock - 2 ch stereo

    I have mine set up simply as:

    Sky HD box - Standard Surround (in this mode my amp automatically changes between Dolby Pro-Logic and DD5.1 depending on whether it sees a stereo signal or 5.1 from my Sky box)

    Blu-ray player - same as above

    CD player - 2ch stereo
