Description: SRT, which stands for ‘Secure Reliable Transport’, is a transport protocol specifically designed for real-time media transmission over IP networks. Its main goal is to ensure the secure and reliable delivery of data, even under adverse network conditions. SRT is based on the idea that the quality of audio and video transmission can be affected by packet loss, latency, and bandwidth variability. Therefore, it incorporates advanced error correction and network optimization techniques, allowing users to enjoy a smooth and high-quality streaming experience. This protocol is particularly relevant in live streaming applications, where immediacy and quality are crucial. SRT is open-source, making it easy to adopt and adapt across various platforms and devices, turning it into a popular choice among media and entertainment industry professionals.
History: SRT was developed by Haivision in 2013 as a solution to the challenges of real-time media transmission over the Internet. The need for a protocol that could handle packet loss and latency in unreliable networks led to the creation of SRT. Since its launch, it has evolved and become a standard in the industry, being adopted by numerous companies and streaming platforms. In 2020, SRT was donated to the SRT Alliance, allowing for its continued development and community collaboration.
Uses: SRT is primarily used in live video streaming, where quality and reliability are essential. It is common in broadcasting applications, streaming platforms, and live event production. Additionally, it is employed in multimedia content transmission in challenging network environments, such as rural areas or during live events where connectivity may be unstable.
Examples: An example of SRT usage is in the live streaming of sporting events, where high-quality video delivery is required despite variable network conditions. Platforms like YouTube Live and Facebook Live have started adopting SRT to enhance the streaming experience. Another case is the use of SRT in live television program production, where a reliable connection between different locations is needed.
