    audio decoding question

    Really confused here because I've read different types of advise.

    I would like the blu-ray player to do the audio decoding.
    Do I use the analogue connections or can I use the HDMI and put the audio setting on "auto" instead of bitstream and set the amp to "pure direct" ?
    Through the analogue connectors the player sounds absolutely fantastic - but the audio is sometimes just a little out of sync (and I don't seem able to correct this).

    ps. I think the audio sync is more due to the tv/amp connection. When the bdp is directly connected to the tv there's no problem

    Hi,

    HDMI Audio on auto, the decoding will be made by the BDP itself

    For audio sync it is BDP related,you have to look in to the BDP menu

    It was as I first thought, but then I read on a forum that a BDP only uses its own decoders through analogue out.

    Love the sound of the 9600, but with some (older) dvd's I prefer the amp to improve the audioquality which is not possible via multi channel in.


    Thanks for your reply

    Output from analogue connectors cannot be syncranised with image (at least with current 9600 fiemware versions).
    Syncronisation works only for HDMI Audio output.

    Dear Philips,
    A few month ago Philips announced an upgrade to enable downmixing from 7.2 to analogue stereo. Is this still on its way? This would be perfect when combined with lip-sync for analogue output, can that too be expected?

    Hi,

    analogue stereo works already - however, the subwoofer channel isn't mixed to stereo yet... Update should come in the comming weeks.

    Hi Toengel,

    Thanks for the reply.
    Lip synchronization for the analogue output, can that be expected as an update for the the 9600 and new in the 9700? Would be a logical combination with the analogue stereo downmixing.

    Hi,

    how do you suggest to test the lip-syc-issue?

    Hi Alex,

    When the blu-ray analogue output goes direct to the stereo amplifier the sound comes to early compared to the sound from the screen-speakers, the latter goes together with the image processing of a picture (image processing takes more time than sound alone). In case the difference in time is considerable, this is visible and experienced as very annoying (people still moving their lips but the sound has already finished). The difference in sound processing speed between the stereo amplifier and the screen can easily be tested by putting on the sound of the speakers of the screen and the speakers of the stereo amplifier at the same time. A double sound with some overlap can be heard. Even in case the difference in processing time of the sound by the two devices is only small, it still can be heard. So a lot depends on the processing speed of the screen, which f.i. in case of the Philips 9956 is not bad at all. Still also in this example the difference in processing speed can be heard: putting on both sound systems at the same time results in an "echo sound", thus slightly out of phase.

    For this is needed small addition in functionality, option "analog audio delay" in range of 0-100 mS (or even 0-50 mS), with steps about 5 mS.
