LiveU LU-30
3G Mobile Uplink System.
LiveU's technology is designed for the delivery of the best possible cellular-based Video transmission quality and resiliency. Its mobility and availability allows you to offer your viewers exciting new content, breaking free fro the limitations of conventional, stationary and expensive satellite links.
So how does LiveU work?
- There are two components to the system; LU-30 battery operated unit (in the backpack) and the LU-1000 downlink server software.
- The video camera connects DV/Firewire input of the LU-30 and the video/audio signal is encoded (H264) and transmitted concurrently via the units 6 internal 3G network data modems.
- The IP address of the destination downlink server (LU-1000) is set up on the LU-30.
The mobile network operators transmit the data traffic to the internet and from there
to the downlink server IP address at the destination. - The LU-1000 server software re-constructs the 3G sub-streams into a single high
quality live video stream. This can be either decoded and output on SDI with embedded
audio for TV production, or repurposed in to Flash for distribution via the web using a CDN

More detail:
- The LU-30 uplink transmitter is equipped with 6 x 3G mobile SIMS and these are
selected for the specific country. In the UK this would normally by 2x SIMS from 3 of
the 4 main operators (Vodafone, T-Mobile, O2 and Orange) - The unit also has Wi-Fi and dual LAN ports for added flexibility. In normal use, the
H.264 encoded stream would be transmitted via the 3G networks, and where connectivity
allows it is possible to use Wi-Fi and LAN instead or in addition to 3G. - The uplink speed is dependent on the network coverage, but typically in urban and
semi-urban areas then the transmission speeds of the 1.5 - 2.0 Mbps are likely. In less
urban, and rural areas the speed can drop of course, but the system will maintain connection
to the LU-1000 downlink server, and will continuously load balance its outbound data to
suit network coverage. - Three models of transmission are possible. In maximum quality mode the end to end
transmission time, or latency, is around 10 seconds. In interview mode, the latency is
just 2 seconds, and in balance mode the system will look at available bandwidth and
balance picture quality and latency. In all 3 modes, once set the latency will remain fixed
for the duration of the transmission, a feature essential for programme production. - In addition to live video mode, there is also a powerful file transfer (FTP) mode than
enables quick transfer of prepared files using the same transmission methods and speeds
as live video.
