MPEG-2 Transport Streams and MOQ: Yes, MPEG-TS Is Still Relevant Today

# MPEG-2 Transport Streams and MOQ: Yes, MPEG-TS Is Still Relevant Today Source: [https://www.red5.net/blog/mpeg-2-transport-streams-and-moq-yes-mpeg-ts-is-still-relevant-today/](https://www.red5.net/blog/mpeg-2-transport-streams-and-moq-yes-mpeg-ts-is-still-relevant-today/) One thing I’ve learned over the years building streaming infrastructure is that new[video streaming protocols](https://www.red5.net/video-streaming-technology/)do not succeed just because they are technically better\. They succeed when they solve real problems while still fitting into how the industry actually operates\. That is part of why I’m excited to see our team becoming more involved with the Internet Engineering Task Force \(IETF\) and the ongoing[MOQ](https://www.red5.net/media-over-quic-moq/)\(Media over QUIC\) standardization work\. Last week,[Paul Gregoire](https://www.red5.net/author/paul-gregoire/), our Solutions Architect, coauthored a[new IETF draft](https://www.ietf.org/archive/id/draft-gregoire-moq-msfts-00.html)together with[Gwendal Simon](https://www.linkedin.com/in/gwendalsimon/), Senior Director for Video Network Technology at[Synamedia](https://www.synamedia.com/), focused on MPEG\-2 Transport Stream packaging for[MOQ](https://www.red5.net/blog/what-is-moq-media-over-quic/)\. The draft reached the front page of Hacker News within hours, but a lot of the discussion there[misunderstood the value](https://news.ycombinator.com/item?id=48049963)of this new draft\. At first glance, MPEG\-2 TS might sound like old broadcast technology, but the reality is that an enormous amount of the world’s live video infrastructure still depends on it\. Contribution feeds, broadcast workflows, satellite distribution, and many existing packaging pipelines all rely on transport streams in one form or another\. So while some people dismiss MPEG\-2 TS as “old,” the reality is that huge parts of the streaming ecosystem still depend on it because it works reliably and is supported across a massive amount of infrastructure and hardware\. In fact, it is used as the transport format in SRT, which according to[Haivision’s 2026 Broadcast Transformation Report](https://www.haivision.com/about/press-releases/2026-broadcast-transformation-report/)is by far the dominant ingest protocol in the broadcast industry today\. And yes, I realize that you can technically use other protocols for the transport over SRT, but 99% of the usage today is MPEG\-TS\. That does not mean newer or better approaches should not exist\. They absolutely should\. But if MOQ is going to succeed in real broadcast and contribution environments, compatibility with existing workflows matters a lot\. This draft is not about excluding newer formats\. It is about making sure MOQ can integrate cleanly into systems people are already running today\. The draft also gets into practical deployment realities that people outside streaming engineering often do not think about enough: - Random access points and stream joining behavior\. - Alternate bitrate track switching\. - Relay and subscriber processing\. - Multi\-program transport stream handling\. - Timing, PCR continuity, and SCTE\-35 signaling\. - Authorization and secure object delivery\. ## Conclusion All of these details become more important as MOQ moves beyond experimental demos and into production broadcast environments, which I explained in my[previous blog](https://www.red5.net/blog/moq-debut-proved-to-be-a-chart-topper-at-nab-2026/)\.
