NAS real-time transcoding
The Intel CPU’s real-time hardware transcoding allows video files that are not supported by the playback device to be first converted into a playable format before being sent to the playback device. With such powerful hardware, even the real-time transcoding of 1080p high resolution video files is a piece of cake.
If bandwidth issues cause playback to become choppy, you can always adjust the resolution of the video stream to create a smoother playback experience.
