請問這樣是PS3+藍光最好的音效了嗎??<有真相>

圖中Linear PCM5.1音軌, 傳輸速率有4.6Mbps

這是最高了嗎??

不是, HDMI能傳的聲音還可以有更高的流量,

基本上那個4.6Mbps, 應該是這樣算來的:
48KHz * 16bits * (5+1) = 4608Kbps = 4.6Mbps.

他只是表示他應該是一個"5.1ch, 取樣頻率48KHz, 解析度16bits 無壓縮格式".
當然,HDMI還可以承受更高的流量, 所以也許是以上三項的其他組合.

不過到最後, 好不好跟片子本身音效製作的品質更有關.

don't know how to calculate. :p

if you have DD TrueHD demo, you can get even >10Mbps! :like: now my disc is at friend's home.... :laugh:

Just calculate "sample rate x resolution x channels" for uncompressed PCM format. and since TrueHD is compressed, it should be < the above result.

http://en.wikipedia.org/wiki/Dolby_TrueHD

According to Wiki, TrueHD itself is capable to carry 14 channel @ 192kHz/24bits. But on BD/HDDVD, it can carry only 8, the encoded bitrate is 18 Mbps. True HD uses MLP compressed format.

So we can estimate it as 8 x 192 x 24 = 36.8Mbps.

Again, according to Wiki, the MLP can provide about 2:1 compression rate.
So the final result became 18Mbps, just the same as the spec.

我想順便問一下，Wii是否沒有光纖輸出?

DTS-HD


DD-PLUS
