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

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. http://en.wikipedia.org/wiki/Meridian_Lossless_Packing 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. |
