Keywords:LiveU Backpack
LiveU has been at the forefront of internet-based live video services for the past decade, and thus has a deep understanding of the intricacies of the online live streaming domain.Problem. In response to these issues, LiveU has developed a stable transmission protocol known as LiveU Reliable Transport (LRTTM). ThisThe agreement integrates the industry's best technologies mentioned above into high-performance encoder products, utilizing a highly compatible protocol, without...It reduces the complexity of system integration. So, how does it achieve this?
Packet Sorting
LRT encodes data packets so that when these packets are received in a jumbled order, they can be reordered according to the encoding.Introduction. This feature is crucial for scenarios involving multi-bandwidth bonding, as data is almost always transmitted in different sequences.Transmitted.
Dynamic Forward Error Correction
The algorithmic technology mentioned earlier is called "dynamic forward error correction." This technology adds some redundant data to video streams,This redundant data can help users achieve a quicker video recovery compared to retransmitting the video. For example, 20%The additional video stream bandwidth provides sufficient redundancy to recover lost packet groups during transmission without the need for retransmission.Request or wait for retransmission. LRT not only uses FEC technology but also employs a dynamic version of FEC. This means that theThe protocol can automatically adjust various parameters of FEC based on the monitored network environment.
Notification and Resend
The LRT notification and retransmission mode is specifically designed for audio and video data transmission. If the packet group is complete,If the delivery is not completed, LRT will send a notification. If some of them are not delivered, LRT will send a message to the initiating end requesting a resend.The data required for the new transmission. Unlike the principle of mandatory verification for each TCP packet, LRT is based on the characteristics of audio and video data to conductThe verification of data packets ensures both the reliability of the data and saves network bandwidth, thereby reducing network transmission.Delay.
Tight coding integration or adaptive bitrate encoding
In LRT protocol theory, one of the most important technologies is dynamic coding technology, which allows LRT to adapt to changes in bandwidth conditions.Automatically identify and notify the video encoder to adapt the bitrate used for video transmission. LRT can operate at any time.Ke can ensure the best quality video transmission under available bandwidth conditions. This guarantees that the transmitted audio and video are suitable forBandwidth capability can minimize buffering time. When the bandwidth environment improves, the LRT will send a signal to the encoder to make changes.Encoder parameters are adjusted and bandwidth consumption for transmission is increased to ensure that video is transmitted at the best quality at any given moment.This reverse flow of information ensures that the video can be continuously transmitted with the lowest latency and the highest quality, regardless of the network.How the network environment is changing.
