Zaxel's 4K Replay Server is a realtime 4K video editing server.

4K Replay Server records 4K 10 bit YUV422 60P video stream and at the same time plays back the video being recorded.  Meanwhile, the operator can create a play list consisiting of clips from the recorded video by specifying the in point and out point and also put pre-recorded video in the storage.  The play list can be played back any time, while the input video is being recorded.

4K Replay Server can be used as a Replay Server for sports broadcasting or a server at theme parks where the operator can change the contents at any time.
