T-21

Independent Technology Publication

Analysis and insights on streaming technology, cloud infrastructure, and enterprise digital systems.

Written for Engineers, Architects & Decision-Makers

T-21 is read by broadcast engineers, streaming media architects, video infrastructure specialists, cloud platform engineers, CDN operators, and technology leaders across media, entertainment, telecommunications, and enterprise organisations where real-time data delivery is mission-critical.

What We Cover

Three Pillars of Coverage

From live broadcast contribution to cloud-native media processing, we cover the technologies reshaping how video and data move at scale.

Streaming & Broadcast Technology

Video encoding and transcoding architectures, OTT delivery pipelines, live contribution workflows, protocol evolution including SRT, RIST, and WebRTC, and the shifting economics of content distribution networks.

Cloud & AI Infrastructure

Cloud-based transcoding and media processing, edge computing for low-latency delivery, AI-powered quality monitoring, automated content operations, and the infrastructure underpinning modern media supply chains.

Enterprise Digital Systems

Enterprise software strategy, digital transformation in media organisations, IT infrastructure modernisation, cybersecurity considerations for broadcast systems, and the convergence of IT and media technology operations.

Our Approach

Analysis Over Announcements

T-21 is not a news wire. We do not chase product launches or rewrite press releases. When a broadcaster migrates to cloud-native production or a new codec standard emerges, we focus on what it means for the people building and operating these systems — not on being first to report the headline.

We write for professionals who understand the fundamentals and want deeper perspective on where the industry is heading. Whether that means evaluating the trade-offs between SRT and RIST for remote contribution, assessing whether cloud transcoding is ready to replace dedicated hardware, or understanding the real-world implications of a multi-CDN strategy — our goal is to provide the context that helps practitioners make better decisions.

The streaming and broadcast industry has no shortage of ambitious visions for the future. What it often lacks is honest assessment of what works today and what remains aspirational. That gap is where T-21 operates. We value clarity over jargon, substance over hype, and practical relevance over theoretical possibility.

About T-21

Originally established as a technical resource for the broadcast and streaming media community, T-21 has broadened its scope as the boundaries between streaming infrastructure, cloud computing, and enterprise IT have blurred. Today it serves as an independent editorial platform covering the technologies and strategies that power how video and data move across networks at scale. T-21 operates independently and is not affiliated with any technology vendor, broadcaster, or industry body.
