Microsoft RDP #2 H.264 AVC444

You need RDP 10 session (Windows 10 / Server 2016) with the following policy enabled.

 Computer Configuration -> Administrative Templates -> Windows Components ->

Remote Desktop Services -> Remote Desktop Session Host -> Remote Session

Environment:

o Prioritize H.264/AVC 444 Graphics mode for Remote Desktop connections

o Configure H.264/AVC hardware encoding for Remote Desktop connections

How it works

 Earlier version of ThinOS RDP H.264 uses Chroma frame 4:2:0.

 ThinOS 8.5 RDP h.264 avc444 technology uses the same decoder to process common h.264

frame and 444 mode frame. A whole 444 frame can be composed using 1 common frame and

1 extra Chroma frame.

 The feature is used to improve the image quality with artificial sharp edges and mounts of

regular color boundaries, like text, so that they can be compressed using the same h.264

technology applied to other type of images.

 For RDP 8.1 session in ThinOS 8.5, it will use the original H.264 frame.

 H264-AVC444 impacts on text and images Chroma, it cannot impact on video quality.

Limitation

 In ThinOS 8.5 the RDP 8.1 session uses the original H.264 frame.
