In today\u2019s world, live broadcasting of various events, whether it be product launches, conferences, seminars, or sports events, both indoor and outdoor, has become immensely popular. This includes broadcasting from remote locations with unstable signals. Live streaming allows everyone to experience the atmosphere of these events, regardless of their physical location. The quality of live streaming has evolved significantly, reaching resolutions like 1080P, 2K, and 4K. However, few people know about the behind-the-scenes technology and equipment required to broadcast these live events. One key component in this process is LRT\u2122 or LiveU Reliable Transport<\/a>. In this article by No More Work, we will explore what LRT\u2122 is and its importance in the realm of current live streaming.<\/p>\n\n\n\n

What is LRT\u2122?<\/h2>\n\n\n\n

LRT\u2122 stands for LiveU Reliable Transport, a protocol developed by LiveU for transmitting video and audio. It is designed to support low-latency, high-flexibility video and audio streaming, making it particularly well-suited for the unique characteristics of cellular 4G\/5G networks, as well as traditional wired and wireless networks. LRT\u2122 is specifically optimized to accommodate multiple IP connections, such as 4G or 5G internet SIM cards, WiFi, LAN, or other internet connections. This technology is integral in ensuring reliable and high-quality live streaming, especially in environments where network conditions are variable or challenging.<\/p>\n\n\n\n

How LRT\u2122 Works and Its Current Stability<\/h2>\n\n\n\n

LRT\u2122, a technology from LiveU, operates on the principle of bonding or combining multiple internet signal channels. This includes various communication channels such as WiFi, LAN, SIM cards (whether 4G or 5G), and other internet connections. All these channels are integrated into the LiveU device. The backend system of LiveU utilizes the LRT\u2122 protocol to transmit video and audio to the cloud or a server system. From there, the signal is converted into formats like RTMP or SRT and then broadcast to platforms like Facebook, YouTube, or any other desired channel for video distribution.<\/p>\n\n\n\n

In the LiveU device itself, the internet comes from multiple sources, including LAN, WiFi, and SIM cards. The number of SIM cards can vary, with the device supporting one, two, three, or even four SIM cards, depending on the requirements.<\/p>\n\n\n\n

This multi-channel approach ensures a high level of stability and reliability in the LRT\u2122 system. By aggregating various internet sources, LRT\u2122 can maintain a consistent and high-quality stream, even in environments where individual internet connections might be unstable or weak. This makes LRT\u2122 an essential tool for professional-grade live streaming in various conditions and locations.<\/p>\n\n\n\n

Current Stability of LRT\u2122<\/h2>\n\n\n\n

Regarding the stability of LRT\u2122 (LiveU Reliable Transport) in the present context, from the perspective of professionals in the production field, LRT\u2122 is highly reliable. If quantified, its reliability could be rated at 99.99%. This high level of dependability is due to its ability to support up to 4 connections on LiveU Solo and 6 on Solo PRO. In the event that one of these signals fails or drops, the remaining signals compensate by enhancing their quality to maintain the stream. This redundancy ensures that the live broadcast can continue smoothly without significant interruptions or quality degradation.<\/p>\n\n\n\n

Such a high reliability rate is crucial in professional settings where uninterrupted and high-quality live streaming is essential. The ability of LRT\u2122 to adapt and maintain performance even when one of the signal sources becomes unstable is a key factor in its widespread adoption and trust in the production industry.<\/p>\n\n\n\n

\"What<\/figure>\n\n\n\n

Advantages of LRT\u2122<\/h2>\n\n\n\n

The key advantage of LRT\u2122 (LiveU Reliable Transport) lies in its ability to manage and adapt to changes in signal quality, particularly when using multiple signal sources. For instance, if you are broadcasting using four different signal sources (like WiFi, LAN, and SIM cards), and one of these sources suddenly drops or experiences instability, the LRT\u2122 system ensures that your video and audio do not disappear. However, it\u2019s important to note that while the stream continues, there might be a slight, momentary drop in quality.<\/p>\n\n\n\n

For example, if your stream initially operates at a bitrate of 6,000, and one signal source fails, reducing the bitrate by 1,000-2,000, the overall bitrate might temporarily drop to 4,000. However, the remaining three signal sources will gradually increase their output to compensate for the loss. Instead of each contributing 1,000 to the bitrate, they might increase their output to 2,000 each, eventually bringing the total bitrate back up to 6,000.<\/p>\n\n\n\n

Even if you\u2019re left with only one signal source, LRT\u2122 can still maintain a high bitrate, potentially up to 6,000. This raises a question: why use four SIM cards if one can achieve the same bitrate? The answer lies in the variability of internet speed. While a single SIM card might reach high speeds during a short test, internet speeds can fluctuate over longer periods, such as during a 1-2 hour event, or even longer broadcasts. Using multiple SIM cards provides a backup in case one loses signal, ensuring continuous and stable streaming.<\/p>\n\n\n\n

In essence, the use of multiple signal sources in LRT\u2122 allows for a more stable and reliable streaming experience. Each source can compensate for fluctuations in the others, maintaining overall performance and quality. This redundancy is crucial for professional live streaming, where maintaining a consistent, high-quality broadcast is essential.<\/p>\n\n\n\n
