12 Channels HD H.265/H.264 HEVC Encoder COL5112HF

COL5112HF 12CH H.265/HEVC Encoder supports up to 3 H.265/HEVC encoding modules with 4 HDMI interfaces on each module. With B frame (IBBP) GOP structure and advanced compressing algorithm, this device enhances picture quality and provides ultra low bit rate to save 75% bandwidth compared with H.264/AVC. It also has 3 data port (1000M/100M) for IP output over UDP/RTP/RTSP protocol and 3 Network Management port to manage the 3 modules individually through 3 different IP addresses. In conclusion, its high performance and cost-effective design make this device widely used in CATV digital head-end, business application, IPTV/OTT system, etc.
