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

The Philosophy of Protocol Adoption

Throughout my career developing streaming infrastructure, I have observed a recurring pattern: technical superiority is not the sole driver of a new video streaming protocol's success.

"Protocols don't win simply because they are 'better' on paper; they win when they resolve actual pain points while aligning with the existing operational habits of the industry."

This realization is exactly why I am enthusiastic about our team's deepening engagement with the Internet Engineering Task Force (IETF) and the standardization efforts surrounding MOQ (Media over QUIC).

The Formula for Success

In mathematical terms, we could view the success of a protocol ($S$) as a function of its technical merit ($T$) and its industry compatibility ($C$):

$S = f(T \times C)$

If $C \approx 0$, then $S$ will remain low, regardless of how high $T$ is.

The IETF Draft: Bridging the Gap

Recently, our Solutions Architect, Paul Gregoire, collaborated with Gwendal Simon (Senior Director for Video Network Technology at Synamedia) to co-author a new IETF draft. This document specifically addresses the packaging of MPEG-2 Transport Streams for use within MOQ.

While the draft gained significant traction on Hacker News shortly after release, much of the community discourse missed the fundamental point. Many critics viewed MPEG-2 TS as obsolete legacy technology. However, the reality of global video infrastructure tells a different story.

Why MPEG-TS Still Matters

Despite its age, MPEG-2 TS remains the backbone of a staggering amount of live video delivery. It is utilized in:

• Contribution feeds (The initial "hop" from source to studio).
• Broadcast workflows (Internal studio routing).
• Satellite distribution (Wide-area delivery).
• Packaging pipelines (Existing transcoding and wrapping systems).

Industry Dominance: The SRT Example

The SRT (Secure Reliable Transport) protocol is currently the leading ingest protocol in broadcasting, according to the 2026 Broadcast Transformation Report by Haivision. While SRT can technically carry other payloads, 99% of its actual usage is MPEG-TS.

Integrating MOQ into Production

For MOQ to transition from a promising experiment to a production-ready standard in broadcast and contribution environments, it must play well with others. It isn't about rejecting progress, but about ensuring a smooth migration path.

Technical Considerations

The IETF draft doesn't just cover packaging; it tackles the "gritty" engineering details that are often overlooked by those outside the streaming field:

• Random Access Points: Ensuring players can jump to specific timestamps.
• Stream Joining Behavior: Managing how a new client synchronizes with a live feed.

Conceptual Data Flow

The following diagram illustrates how MPEG-TS can be encapsulated within the MOQ framework to maintain compatibility:

To visualize the packaging, consider a simplified conceptual representation of a transport packet:

// Conceptual MOQ Packet containing MPEG-TS payload
struct MoqPacket {
    uint32_t sequence_number;
    uint8_t  payload_type = 0x01; // MPEG-TS Indicator
    byte     ts_payload[188];     // Standard MPEG-TS packet size
};

Final Thoughts

As MOQ evolves from a demo into a production tool, these integration details become paramount. For a deeper dive into this transition, refer to my [previous blog post].
