Hitless Protection for SRT Transports

In the intricate landscape of live broadcasting and video streaming, the challenge of delivering high-quality content under the unpredictable conditions of internet connectivity persists.

Comprimato, a leader in high-performance video processing technology, addresses this challenge by incorporating SRT Path Redundancy, also known as 2022-7 Hitless Protection, into its software products, such as the Live Transcoder and Live Standards Conversion.

Understanding SRT Path Redundancy

SRT Path Redundancy is an advanced feature of the SRT protocol that ensures the reliable transport of video feeds over two separate internet paths. This method is crucial for maintaining uninterrupted streaming, as it provides a fail-safe by sending duplicate video packets over diverse routes, optimizing packet delivery to maintain stream integrity, even under varying network conditions.

Adopting a strategy akin to SMPTE 2022-7 Hitless Protection for the SRT protocol, SRT Path Redundancy offers seamless protection switching and redundancy for video streams, significantly enhancing stream reliability and quality.
