MCP78真的支持HDMI1.3a?真的支持LPCM5.1?完美吗?

有点懒

搜索"MCP78  HDMI1.3"和"MCP78  LPCM".   结果是:支持.
可是:
1.  有的大侠说:不支持.   被彻底否决.
2.  有的大侠说:部分支持.   即:不完美.
我该听谁的?
请完美解答.
谢谢.

NVIDIA GeForce 8200 -

NVIDIA has been discreetly working on the GeForce 8200 for the past several months and introduced it at CES 2008.  We have provided preliminary details on new features like HybridPower and Hybrid SLI (GeForce Boost) along with NVIDIA already providing early specifications on their website.  The GeForce 8200 is shaping up to be a formidable competitor to the AMD 780G and from all indications an excellent uATX platform for SOHO or HTPC applications.

After posting some early comments about the 780G chipset, we had a flood of requests wondering about the HDMI output capabilities of the GeForce 8200. We will have further details later today but at this time the chipset is HDMI 1.3a "compliant".  The mGPU does not support the additional 12-bit or 16-bit deep color modes but meets the other video specific criteria.  Also, 8-channel LPCM output is fully supported but transporting a TrueHD or DTS-HD (MA) audio stream is not available.  Update 2-  From NVIDIA:

"The ISV player (Intervideo or Cyberlink) will demuxe the audio stream from
the HD/BD disc. If it's a TrueHD or DTS-HD audio stream, the 8200 does
not support transporting these across HDMI. The application can instead decode
it and output it as uncompressed audio (multichannel LPCM) with no loss
of audio quality."

In the meantime, we have to continue to express our concerns about the lack of multichannel LPCM output over HDMI in the AMD 780G product.  Intel has already introduced this feature in the G35 chipset and NVIDIA will be introducing it later this month or in early March.  

The specifications and features of the 780G and GeForce 8200 are very similar and most users will probably be satisfied with either solution.  However, when it comes HTPC duty, generally the more advanced features the better, and in this case having multichannel LPCM output is an important distinction.  We will have to wait to compare the video quality of AMD's UVD technology to the revamped NVIDIA PureVideo HD engine along with Hybrid CrossFire versus Hybrid SLI, but right now it appears NVIDIA is a couple of steps ahead in the audio area.

简单地说，I的35有了，N的马上，A的还没消息

1.支持，LPCM支持到7.1声道输出，但是不支持TrueHD和DTS-HD的未解码的bit stream传输，只能是解码后用LPCM格式输出

2.现在对LPCM的实现，取决于驱动和播放软件，都还不够完善，特别是驱动，但这迟早不是一个问题。
