The KDS-EN4 is an H.264, MPEG-4 encoder for HDMI signals with a resolution of up to 1080p60 (YUV 4:2:0) with audio stereo (miniJack 3.5 mm) embedding and RS-232. All signals are encoded and transmitted as an IP stream in real time using the RTSP protocol in Unicast (one-to-one) or Multicast (one-to-many) modes. The role of receivers can be taken on by KDS-DEC4 decoders or a computer with VLC® player installed.
