The LU200 ultra-small unit is the first of its kind, standing in a category of its own within the broadcast market. The LU200 fills out LiveU’s solutions for broadcasters, while offering an attractive price, form-factor and performance for other markets.
Weighing just over 500 grams (1.1 lbs) and available in a pouch or camera-mount configuration, the LU200 provides a highly cost-effective and easy-to-use unit for live video transmission anywhere in the world. The LU200 supports two 4G LTE/3G modems together with WiFi and LAN connections and includes LiveU’s proprietary antenna modules for extra resiliency. This two-modem bonded solution is compatible with any camera and is ideal for broadcasts on the fly. The flexible LU200 can also serve as a stand-alone video encoder or be used as a LiveU DataBridge mobile hotspot for general connectivity in the field.
The LU200 is fully incorporated with LiveU’s multilayered live video ecosystem and can be locally or remotely managed via LiveU Central, the unified management platform for LiveU’s field-units. As the hub for video ingestion, LiveU Central allows broadcasters to acquire both live and recorded content from the field, preview it centrally or remotely, broadcast it live or in scheduled programming and distribute it to any location.
LiveU’s unique Reliable Transport protocol (LRT™) is at the heart of LiveU products to deliver optimized video performance. LRT™ enables reliable, low delay live video streaming over non-guaranteed IP networks and ensures reliable transport over the most unreliable of networks, including cellular networks - allowing you to acquire exciting live content in even the most remote locations.
LRT uses numbered packets so that the packets can be re-ordered when they arrive out of order. Packet Ordering is an absolute requirement with connection bonding, where data usually arrives in a different order than intended.
Forward Error Correction (FEC) adds some overhead to the stream to recover lost data faster. LRT automatically varies the FEC parameters based on monitored network conditions.
LRT can acknowledge large groups of packets if they all arrived. If some did not arrive, it can inform the streaming engine to resend needed data. By acknowledging large groups of packets at a time, LRT uses less overhead and latency. Unlike UDP, LRT gives complete feedback loop so the user knows that the data is arriving correctly.
As the bandwidth condition changes, LRT automatically recognizes this and informs the video encoder to allow it to adapt the bit rate of video it is delivering and keep the best possible stream within the available bandwidth at any given moment.
