swoond ,我找到了你转的那篇文章的英文
我也转几段过来:
Likewise, decoding (unpacking) a soundtrack in the player or in the receiver will yield the exact same results. It's not like high end receivers have a special secret version of TrueHD decoding reserved for them that cheap players aren't allowed to have. It's just format decoding. If certain audio data is flagged for the left front channel, then decoding in the worlds most expensive receiver won't place that data somehow "more" into the left front channel than decoding in the world's cheapest player.
大致意思就是播放器解码还原出来的东西和功放解码还原出来的东西完全一样,即使是high end receivers和廉价的播放器,他们解出来都一样,因为是无损压缩的,就像zip一样。
[Updated Audio News (November 14, 2007): Since this article was first written, Toshiba has implemented a firmware upgrade to their HD-XA2 and HD-A35 HD DVD player models that adds a feature called "Direct Digital Audio Mode." This function serves as a workaround for the Advanced mode bitstream limitation. When activated, the player will transmit the raw audio bitstreams for any of the new high-resolution sound formats to a receiver for decoding, even on Advanced discs. However, it will only transmit the movie soundtrack itself, not any additional content such as menu beeps or Picture-in-Picture audio. The upcoming Onkyo DV-HD805 HD DVD player will presumably also offer this function. Some recent Blu-ray players such as the Samsung BD-P1400 and the Panasonic DMP-BD30 have a similar feature.]
东芝的HD-XA2和HD-A35播放机,能够传输bitstream到功放,即使是Advanced mode,但也只是电影本身的音轨,没有其他的内容,比如菜单按键声音,画中画评论声音。
