LLC-4000 is a 4K video encoder/decoder system featuring accurate Videostream bandwidth management called PRC (Peak Rate Control).
This featureenables to transmit 4K Video over 5G networks without multiple mobile network bonding.

Features

• 4K 60fps/5-20Mbps (Uplink 5G)
• Full HD 60fps/3Mbps, 30fps 1.5Mbps (Uplink LTE)
• Glass to Glass Low Latency system over Private 5G
  (Encoder/Decoder latency is less than 50 msec)
• No need to consider video packet buffer and burst traffic
  (PRC enables to control Video packet bandwidth. CBR cannot manage precisecontrol.)
• Bandwidth addition is quick and easy.
• Error Correction features (FEC, ARQ, SRT)

Video Streaming Protocol Flexibility
Multiple video streaming protocols are supported including UDP, RTSP/RTP, and multicast.
Additionally, both IPv4 and IPv6 networks will be supported.

Narrowband Video Quality Control
Our Peak Rate Control technology precisely manages input bandwidth so not to exceed a specified maximum, enabling stable and reliable video transmission that maintains clear video quality even in heavily constrained networks.
In addition, Forward Error Correction and ARQ (retransmission control) can be enabled for error concealment and secure transmission.

RoI (Region of Interest)
ROI mode when enabled maintains clear video quality in a selected area while input bandwidth is limited to a specified data rate.
The selected area can be changed from the management portal.

Video Display Output
Up to four streams can be simultaneously decoded and output in a four way split screen mapped display.

Video Input/Output
Video input/output by HDMI is supported directly.
Additionally, HD-SDI is supported via video converter.

Audio Input/Output
Audio input/output via either HDMI or USB interface.Specification*1 : 1080I @ 50,60Hz input is converted to progressive format and encoded
*2 : This function is not supported by SRT and RTSP protocolsProduct Appearance
