E fin qui, nessuna novità. Continuando però...Dolby TrueHD ha detto:Since our visit was prompted by our post about using Dolby TrueHD with a PS3, we'll start with the lossless format. Specifically, we received several field reports about sonic differences between decoding the TrueHD track in the player (sending LPCM to the receiver) versus bitstreaming the TrueHD to the receiver for decoding. Well, you can take off your tinfoil hats -- Dolby TrueHD is not only encoded as lossless, but it also has a built in CRC (cyclic redundancy check) that ensures that the decoding process is lossless as well. Additionally, Dolby does do testing of components to ensure, for example, that the amplifiers are accurate.
That said, the amount of signal processing in modern AVRs can introduce some wrinkles that, quite frankly, are beyond Dolby's control. For example, on a PS3 it is important to disable Dynamic Range Control to ensure that the decoded TrueHD bits aren't being subjected to additional gain stages before being passed into your receiver. Also common are signal processing steps in the receiver that depend on the source data -- for example, some receivers apply room EQ to LPCM, but not Dolby TrueHD. At the end of the day, it's up to you to make sure that the signal processing chain you set loose on your Dolby TrueHD signal is under control before making comparisons."
So as you can see, there is no guarantee that the PS3 does proper decoding or that it doesn't do any post processing to the LPCM prior to it hitting the Receiver. However, if you have a Dolby authorized Receiver like a nice Denon or Onkyo you know you are getting prefect decoding via the built in CRC checks.
Questa invece mi è nuova. E' possibile che la PS3 faccia pasticci scalando il numero di canali da 7.1 a 5.1. Altro possibile punto critico da considerare.Another requirement of Dolby TrueHD is that it can do proper down-mixing of 7.1 to anything lower down to 2.0. Most people have a 5.1 setup and if the Receiver does the decoding, you can be sure it does proper down-mixing so you don't miss any sound and it is places in the proper speaker. If you let the PS3 do the decoding, you might completely miss what was in the extra 2 channels or it may not come out the correct speaker mix.
Vero, giusto, corretto, perfetto... però, almeno ci si toglie dalla testa ogni possibile dubbio.morrocoy ha detto:per chi ha già la "fat PS3" e vuole la nuova "slim PS3" solo per sentire meglio le nuove codifiche, spenderebbe 99€ solo per leggerle sul display dell'ampli senza migliorare nulla.
Dissento nella maniera più assoluta...se la decodifica la fa l'amplificatore, invece della PS3 fat, stiamo ascoltando praticamente "2 tracce diverse".morrocoy ha detto:Quindi, per chi ha già la "fat PS3" e vuole la nuova "slim PS3" solo per sentire meglio le nuove codifiche, spenderebbe 99€ solo per leggerle sul display dell'ampli senza migliorare nulla.
