The H.264/MPEG-4 is a video compression format and one of the most used formats for recording, compression, and distribution of high definition video. And, of course, it plays an important role for those running Windows 8. Now, as Microsoft has made the Windows 8.1 update available, there have been improvements to the H.264 codec, as well.

Ayesha Mascarenhas, a Program Manager on the Remote Desktop Virtualization team, has shared more details regarding it on a recent blog post. Here are some of the highlights:

With Remote Desktop protocol version 8.1, we have further enhanced RemoteFX adaptive encoding by extending H.264 support to images as well. This enables RemoteFX to offload all image decode processing to an AVC/H.264 hardware module. So both image and video decode is offloaded to the AVC/H.264 hardware module, and only text decode continues to be performed on the CPU. Devices such as Windows Surface RT take advantage of this RemoteFX improvement in Windows 8.1, delivering a great remoting experience in the form of significantly higher frame rates compared to Windows 8.

To learn more about the H.264 codec and its meaning for Windows 8.1 devices, then I suggest to have a look at this older post, as it has more details that will probably be of interest especially to developers.
