As a final highlight, a multi-view showing 16 hops in order of the chain was streamed to YouTube Live, utilizing the SRT protocol. Notably, the video and audio signals remained error-free across all 18 hops, two times around the world.Īlthough latency was not fine-tuned during the spontaneous growth of the chain, it was surprisingly low. The chain involved nine different vendors, all successfully connected via the SRT protocol – Haivision, Sienna, Tellyo, GlobalM, Blackstar Group, Techex, Live X, OBS Studio, and Switcher.ai. An SRT live stream from a Haivision Makito X was made available to be picked by the next instance, which made the stream available again for the next solution in the chain. A world record longest SRT inter-vendor chainĭuring Friday’s testing, what started out as a fun idea developed into a significant test. Participants of the program will be contacted by YouTube in early June. The feedback given by the participating vendors was very positive, highlighting the low latency, good coverage of nearby entry points, and independence of codec choice such as H.264 or HEVC up to 4Kp60. This exclusive early access was given to Plugfest participants to test SRT as a replacement for RTMPs ingest and to start populating the YouTube Live Verified Device list on their help center. YouTube Live introduces SRTĪs part of this year’s Plugfest, YouTube introduced their “Live Verified Encoder Program” which aims to ensure the production hardware of vendors seamlessly interfaces with YouTube Live using SRT. This collective effort not only improves individual products but also drives the overall advancement of the SRT ecosystem. Engineers and experts from different organizations including Appear, Blackstar Group, Bitmovin, Canon Inc., Cinegy GmbH, Cloudflare, Colorfront, Evertz Microsystems Ltd., Epiphan Video, GlobalM, Gridshot, Haivision, Intinor, Live X, Matrox, Nanocosmos, OBS, Rivet, Ross Video, Sienna, Streamworks, Switcher.ai, TAG V.S., Techex, Telstra, Tellyo, ToolsOnAir, VideoLAN VLC, Volkert Software, Wowza Media Systems and YouTube came together to exchange insights, troubleshoot challenges, and optimize their solutions for seamless integration with SRT. SRT connects two endpoints for the purposes of delivering low latency video and other media streams across lossy IP networks such as the public internet. The collaborative nature of the Plugfest was instrumental in sharing knowledge and developing best practices within the SRT community. SRT is a low latency video streaming transport protocol and technology stack designed to optimize video streaming reliability, security, and performance. This surge in participation reflects the growing importance of SRT interoperability within the streaming industry. Throughout the event, a total of 2,257 individual device-to-device tests were conducted, demonstrating a 51% increase in testing compared to previous years. There was an impressive turnout for the 2023 edition of the SRT InterOp Plugfest with 32 vendors actively participating and collectively providing 55 devices and software solutions for testing with other members of the community. Keep reading this post for some of the key highlights from this year’s event! An increase in participation and testing Beginning on May 9 th and spanning an entire week, this year’s Plugfest showcased remarkable participation and engagement from vendors, resulting in extensive device-to-device tests and fostering the continued growth of the Secure Reliable Transport (SRT) protocol. Since then, support for the protocol has continued to grow and in 2018 Haivision was awarded an Emmy® Award by the NATAS Technology & Engineering Achievement Committee for pioneering a reliable transmission method for live contribution and distribution TV links.This year’s SRT InterOp Plugfest was a pivotal event for testing interoperability and compatibility within the streaming industry. To encourage widespread adoption so that more companies and customers could benefit from this game-changing technology, Haivision released SRT on GitHub in 2017 as an open-source technology stack and protocol. It was publicly demonstrated for the first time at IBC 2013, and, as the technology progressed, Haivision included SRT as part of its product family so that customers could enjoy the benefits of high-quality, low latency, secure video over unmanaged IP networks, including the internet. It accounts for packet loss, jitter, and fluctuating bandwidth all while maintaining the integrity and quality of video.īorn from the need to reduce the prohibitive cost of live broadcast contribution over satellite links and dedicated fiber, SRT was originally developed and pioneered by Haivision. In a nutshell, SRT brings the best quality live video over the most unpredictable networks. SRT connects two endpoints for the purposes of delivering low latency videoĪnd other media streams across lossy IP networks such as the public internet. SRT is a low latency video streaming transport protocol and technology stack designed to optimize video streaming reliability, security, and performance.
