Bringing Bonded Transmission to Mobile Phones
LU-Smart bonds your smartphone's internal WiFi and 4G/5G cellular connections to reach optimal video quality and resiliency. External MiFi can alsos be added, enabling the bonding of two cellular connections in a single smartphone. LU-Smart supports the most popular iOS and Android devices.
Part of Your Workflow
LU-Smart connects to your existing LiveU decoding servers (physical or cloud) and is monitored and managed via LiveU Central, the unified cloud-based management platform for LiveU's units.
Guest Interviews Made Simpler
Conduct live interviews with guests from their home/office location without any prerequisites or technical knowhow from their side! The LU-Smart Guest Interview lets you send a link to your guest’s smartphone (over email/SMS) and get them live on-air quickly.
Superior Camera Features
LU-Smart boasts an attractive GUI with superior camera features, including auto focus/manual focus, exposure control and grid, and support for Bluetooth audio devices.
Advanced Video Modes
LU-Smart supports various video modes such as live, live & store, store & forward, and store in gallery. It also includes built-in metadata support allowing you to send an XML Metadata file to the LiveU server for processing by a MAM system.
LRT™ (LiveU Reliable Transport)
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.
PACKET ORDERING
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.
DYNAMIC FORWARD ERROR CORRECTION
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.
ACKNOWLEDGE AND RESEND
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.
ADAPTIVE BIT RATE ENCODING
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.
