LiveU LRT (LiveU Reliable Transport) is a video and audio protocol developed by LiveU over the last decade. LiveU is a pioneer in the field of live video broadcasting and has become a leader in the industry, providing solutions for broadcasters, production companies, and businesses of all sizes. The importance of reliable video transmission cannot be overstated. Live video broadcasts, whether it’s news coverage, sports events, or corporate meetings, require a reliable network to deliver high-quality, uninterrupted video content to viewers.
What is LiveU LRT?
LiveU LRT is a low-latency, high-resiliency video and audio protocol that is designed to accommodate the special properties of cellular and LTE networks. It’s not only a point-to-point protocol but is also built to support bonding of many connections. This means that LiveU LRT can bond several cellular or other network connections to provide a robust and reliable connection for live video broadcasting.
Features and benefits of LiveU LRT
One of the key features of LiveU LRT is its ability to bond multiple connections, such as 3G/4G, Wi-Fi, and LAN. Bonding these connections provides redundancy, increased bandwidth, and reduced latency, resulting in a stable and reliable network connection. LiveU LRT also supports Adaptive Bitrate Encoding, which automatically adjusts the video quality based on the available bandwidth to ensure optimal stream quality. Additionally, LiveU LRT offers Dynamic Forward Error Correction (FEC) to recover lost data faster and Packet Ordering to re-order packets when they arrive out of order. LiveU LRT also uses Acknowledge & Resend, which informs the streaming engine to resend needed data.
Comparison to other video transmission protocols
LiveU LRT offers several advantages over other video transmission protocols. Traditional protocols, such as RTMP or RTP, have a high latency and limited resilience in challenging network conditions. On the other hand, LiveU LRT is designed for live video broadcasting and provides a low-latency, high-resiliency connection. LiveU LRT also has the ability to bond multiple connections, providing redundancy and increased bandwidth, which is not possible with other traditional protocols.
How does LiveU LRT work?
LiveU LRT uses a unique combination of advanced algorithms and technology to provide reliable video transmission. LiveU LRT technology is designed to optimize the transmission of data over multiple cellular or other network connections. The bonding of these connections is done through proprietary algorithms, which enable the transmission of video data over multiple paths simultaneously. This not only provides redundancy but also increases the bandwidth available for transmission.
Bonding multiple connections for optimal transmission
LiveU LRT uses a process called bonding to combine multiple cellular or other network connections to provide a robust and reliable connection. This process ensures that the transmission is not disrupted, even if one or more of the connections fail. Bonding is done using advanced algorithms that combine the different paths and ensure that the data is transmitted over the optimal path.
Packet Ordering for reordering packets
Packet Ordering is a process used by LiveU LRT to ensure that packets are transmitted in the correct order. When transmitting data over multiple connections, packets can arrive out of order, which can cause delays and even lost data. LiveU LRT uses numbered packets so that the packets can be re-ordered when they arrive out of order.
Dynamic Forward Error Correction for data recovery
Dynamic Forward Error Correction is used by LiveU LRT to recover lost data faster. FEC adds some overhead to the stream, which enables the receiver to recover lost data. LiveU LRT automatically varies the FEC parameters based on network conditions to ensure that the data is recovered as quickly as possible.
