Starting next Tuesday, Radeon X1000 owners will be able to download, for free, ATI's Catalyst 5.13 driver and a Cyberlink H.264 decoder that hooks into ATI's GPU and enables hardware acceleration of H.264. More specifically, ATI's Radeon X1000 GPU in combination with the Cyberlink H.264 decoder will handle the in-loop deblocking, motion compensation and inverse transform that occur during H.264 decoding. Unfortunately, ATI only had a beta ready for us in time for this review, so there were some bugs. Right now, ATI is hoping to have the final version available on the 22nd.

The end result is that CPU utilization is reduced, making the playback of H.264 movies possible on lower end systems and have less of a performance impact on all systems. ATI's work on H.264 decode acceleration today is extremely important because H.264 is the codec of choice for both Blu-ray and HD-DVD.

So how does it work? It's all fairly simple. You just install the Cyberlink H.264 decoder, which then lets you play, with ATI GPU acceleration, H.264 content in Windows Media Player. The bundle also includes an ATI skin for Windows Media Player, but thankfully, you can revert back to the original WMP skin.

催化剂5.13下周2推出！前瞻软件抢先看
作者：P2MM 编辑：P2MM　2005-12-17 8:24:00

ATi准备在下周2为ATi用户带来圣诞节礼物，即催化剂5.13驱动程序。今天多家网站推出催化剂5.13驱动程序Avivo功能前瞻：

1/催化剂5.13驱动程序提升硬件MPEG-2回放性能和质量，改进其中的矢量自适应去交错算法，提升多格式侦测，提升时间回归降噪能力。

2/X1800显卡搭配催化剂5.13之前的驱动程序在视频质量测试软件HQV Benchmark当中得分38分，搭配催化剂5.13驱动程序得分108分，质量提升2.84倍！

3/目前市场上没有处理器可以流畅地软件加速H.264视频播放。催化剂5.13是第一款支持H.264硬件加速的ATi驱动程序，支持全系列Radeon X1000芯片的硬件H.264加速。但是加速程度如何还要取决于Radeon X1000显卡的级别，其中ATi建议X1300显卡用来进行480p、576p H.264流畅加速播放，建议X1600显卡用来进行720p H.264流畅加速播放，建议X1800显卡用来进行1080i和1080p H.264流畅加速播放。这可能让购买低端X1000显卡，而希望进行1920x1080 H.264流畅加速播放的用户失望，但是ATi的建议合乎逻辑，因为H.264画质越高，硬件加速需要动用的像素计算资源越多。
