This summer, a software update from CrowdStrike caused millions of computers worldwide to crash. The scale of this system failure was unprecedented, significantly impacting various industries globally. The blue screen incident highlighted the vulnerability of global IT systems to single points of failure (SPOF), while also raising a critical question: how can we reduce the risks associated with single points of failure? Mitigating single points of failure is also crucial during real-time video transmission, as there is only one chance for each live broadcast.
In addition to the widespread adoption of LiveU's solutions by globally renowned clients in the broadcasting and sports live streaming industries, many government public agencies have also introduced LiveU, primarily for public safety and emergency response. In critical situations such as natural disasters or public emergencies, LiveU's technology ensures the uninterrupted communication of important information to the public.
IPThe charm of binding, instant communication recovery.
LiveU IPThe video ecosystem is built on two fundamental principles: ample redundancy and diversity, which reduce the risk of single points of failure and enable rapid recovery of communication. Cellular Bonding VoBIP (Video-over-Bonded-IP) is a patented technology from LiveU that is centered around these two principles. With cellular bonding, wireless video transmission can utilize different connections from multiple communication providers, ensuring seamless connectivity even in harsh network environments.
Cellular bonding technology combines 4G and 5G communications, while also allowing for the use of Ethernet, WiFi, and satellite. In the event of a weak or failed connection, it instantly compensates with other connections to ensure uninterrupted transmission. IP bonding technology is continuously evolving and maturing, transitioning from a backup solution to a primary mode of video transmission.
Active Redundancy
LiveUReliable Transmission (LRT)™LiveU Reliable Transport (LRT) is a proprietary audio and video transmission protocol developed by LiveU, proven in the field, that supports low-latency and stable transmission. After optimization, LRT™Supports binding with multiple IP connections. Unlike some audio and video transmission protocols that focus on active-passive redundancy, LRT™Utilizing active-active redundancy, seamless connection switching is achievable.
Forward Error Correction (FEC) is also an important technology in audio and video transmission protocols, as it reduces the impact of packet loss while providing a seamless viewing experience. Although FEC technology adds some cost to the data stream, a small amount of additional cost can recover lost data more quickly than resending it. For example, an additional 20% bandwidth can generate enough redundancy to recover an entire set of lost packets without the need to request or wait for data to be resent. LRT™The forward error correction is dynamic and will automatically adjust the amount of forward error correction data used based on the monitored network conditions.
Multiple channels, minimal risk
In the fields of wireless video transmission and live broadcasting, the diversification of network providers effectively reduces single-point risks. The diversity of suppliers is at the core of IP bonding technology and is a fundamental principle of the LiveU system architecture. LiveU collaborates with multiple Mobile Network Operators (MNOs) and Mobile Virtual Network Operators (MVNOs). As a result, customers can access mobile communication networks or wireless networks from various telecom providers, eliminating the risk of relying on a single supplier or wireless network. Although the CrowdStrike blue screen incident affected one of LiveU's MVNO partners, the diversity of available networks ensured that our customers were not impacted and did not report any issues, allowing all of LiveU's ecosystem solutions to operate as usual. In fact, LiveU's technology compensated for the problems faced by other affected broadcasting systems.
With extensive experience handling over 10PB of cellular data each year, LiveU has accumulated a wealth of expertise in optimizing data connections and supporting flawless live broadcasts.
