ArcSoft's Upscaling Technology, SimHD, Is Being Demonstrated at
NVISION 2008
FREMONT, Calif.--(Business Wire)--
ArcSoft, Inc. announced today that ArcSoft TotalMedia Theatre, its
universal multimedia player, now supports NVIDIA CUDA which provides
DVD upscaling through Graphics Processing Units (GPUs).

Devising its SimHD post processing technology with NVIDIA CUDA,
ArcSoft is accelerating TotalMedia Theatre's DVD upscale performance
on GPUs to deliver viewers a close-to-HD video from the standard
definition multimedia files and DVDs, offering them a sharper and more
vivid picture in real time.

"The newly released, CUDA-powered SimHD technology is available in
TotalMedia Theatre to allow viewers to obtain a HD-like viewing
experience from not only DVDs, but also other standard definition
multimedia files," said George Tang, ArcSoft Vice President and
General Manager of Video and Home Entertainment Group. "We are pleased
to be partnering with NVIDIA to deliver excellence in high-definition
video on the PC."

"CUDA provides our software partners an environment to develop
high-level applications utilizing NVIDIA GPU accelerations," said
Patrick Beaulieu, NVIDIA's Product Marketing Manager, Multimedia
Group. "ArcSoft SimHD technology in TotalMedia Theatre sets a great
example whi**arnesses the power of NVIDIA GPUs for much-enhanced
video processing."

TotalMedia Theatre utilizes general purpose GPUs (GPGPU) to
provide sufficient power for intensive post processing technology such
as SimHD. The application is compatible for use with NVIDIA GeForce 8
and 9 series GPUs. ArcSoft will continue working to deploy other
technologies on NVIDIA CUDA.

ArcSoft TotalMedia Theatre with SimHD technology will be available
in Q4, 2008. For a live demonstration, visit NVIDIA (booth 220) at
NVISION 08, taking place at the San Jose McEnery Convention Center in
downtown San Jose, CA. For more information about the product, please

这个不错
超采样用CPU做很费劲的

Arcsoft 还是小有名气的
不过我觉得upscale没啥意思吧.

CUDA対応を無効にしてCPUによる処理に切り替えると、CPUの利用率が一気にあがり、6fpsしかデコードできない

画面质素、性能提升明显亚 {shocked:]

看来CUDA前景光明。A饭请不要酸哈。{shy:]

upsampling的方法就是在sample之间填零, 然后做Low-pass filtering(一般用FIR). 而FIR
就是lattice结构,所以用GPU做起来比较得心应手. 不过AMD已经用硬件实现了1080P到更高分辨率的upsampling, 估计480P的DVD也很容易.
当然用CUDA实现的灵活度更大些, 例如可以选用不同的FIR来达到不同的画面效果

美商虹軟今日宣布其多媒體播放器，ArcSoft TotalMedia Theatre支援 NVIDIA CUDA技術，以繪圖處理器(GPU)進行影像強化的密集數據咚恪?r

藉由SimHD與NVIDIA CUDA的結合，虹軟利用繪圖處理器的加速計算提升了TotalMedia Theatre，可將標準解析(standard-definition)的多媒體檔案及DVD光碟內容以近高解析(high-definition)的畫質呈現給觀眾。

虹軟視頻和家庭娛樂事業群副總裁兼總經理George Tang指出「虹軟最新發表的SimHD技術已被哂迷贏rcSoft TotalMedia Theatre中，可以讓DVD及標準解析多媒體檔案以近高解析的畫質播放，提升觀眾的視聽體驗。」

NVIDIA 多媒體部門產品行銷經理Patrick Beaulieu指出「CUDA提供NVIDIA的軟體合作夥伴一個可以利用繪圖處理器加速來開發高階軟體的環境。ArcSoft TotalMedia Theatre 就是一個有效哂肗VIDIA 繪圖處理器強大功能的最佳示範。」

TotalMedia Theatre採用通用圖形處理器(GPGPU)，為密集的後處理技術，例如SimHD，提供足夠的計算能力。程式與NVIDIA GeForce 8和9系列GPU兼容。虹軟將持續地研發其他支援NVIDIA CUDA的技術。

哂肧imHD技術的ArcSoft TotalMedia Theatre將於2008年第4季度出版，並於聖荷西McEnery會展中心舉行的NVISION 2008 NVIDIA攤位(220)展出。如需了解更多有關產品的詳情，請訪問http://www.arcsoft.com/intouch/totalmediatheatrepr 。

有没有先另当别论。其实UVD2和PV3这种才叫硬解……软解就无所谓有没有此功能了。大家都支持。这种方法是软解加速……以后NV也可以用CUDA帮不支持PV3的NV老卡例如8800GT、GTX之流做个接口解码VC-1，但也不能因此叫 ...

upscale的是decode以后的视频

这两图是赤裸裸的误导图……实际效果要看截图……证据太明显了……请看图上CPU占用栏，左边非常模糊，恰似左边的图像，越往右却越清晰……

很专业阿
