Channel 4: Building a Modern Multi-Vendor Media Supply Chain

About Channel 4

Channel 4 is a free-to-air, commercially funded public service broadcaster in the UK. It operates the UK's biggest free streaming service, Channel 4 Streaming, alongside a network of five linear television channels. Its purpose is to create change through entertainment: representing unheard voices, challenging with purpose, and reinventing entertainment. As a publisher-broadcaster, Channel 4 commissions UK content from the independent production sector, working with around 300 creative companies across the UK every year.

The Challenge

Channel 4, as part of its next-generation business architecture, chose to transition from a single vendor to a multi-vendor media supply chain. It needed a next-generation supply chain technology platform to orchestrate workflows and business processes across multiple suppliers and vendors for every asset.

BRAHMA AI deployed BRAHMA AI Core, tailored for a multi-vendor supply chain network, to meet Channel 4's objective.

The Solution: BRAHMA AI Core, a Cloud-Native Media Supply Chain Platform

All communication between BRAHMA AI Core and Channel 4's other vendors, including Access Services, Post-production, and Playout, runs through common interfaces, with metadata and media securely managed over the cloud.

By enabling an automated multi-vendor content supply chain, BRAHMA AI Core gives Channel 4 the following:

1. Visibility

BRAHMA AI Core provides complete visibility across vendors, processes, and timelines. Real-time dashboards give Channel 4's Media Management team full operational and departmental transparency.

2. Managing Changing Priorities

With multiple vendors involved, changing priorities need to cascade across the supply chain. BRAHMA AI Core's Advanced Schedule automates task assignment, dynamically updates priorities, and keeps every stakeholder informed.

3. Scalability

Built to support the dynamic streaming demands of Channel 4 Streaming, BRAHMA AI Core uses volumetric and schedule data to automatically scale the pipeline and cloud services based on demand.

4. Archive Migration and Digital Asset Management at Scale

The project focused on building a modern, connected supply chain with zero disruption to Channel 4. BRAHMA AI Core migrated 7.5 PB of Channel 4's archive, including 700,000+ video assets and 450,000+ audio and subtitle files. The platform now manages approximately 1.65 million assets, and counting.

5. Modernization

Cloud-Native Platform
BRAHMA AI Core is cloud-native and purpose-built for hybrid deployment. It lets workflows run across cloud and on-premises storage and connect with adjacent systems such as Auto QC, cloud and on-premises transcode engines, and OTT packaging solutions.

This has helped Channel 4 move away from legacy processes toward a modern, flexible media supply chain.

Metadata Tagging and Content Intelligence Toolkits
BRAHMA AI Core provides tools for timecode capture, content identification, and quality checks, giving Channel 4 and BRAHMA AI operations teams the content intelligence they need to make informed decisions and manage workflows efficiently.

Advanced Schedule
Integration with Channel 4's broadcast scheduling and rights system enables forecasting and resource planning for activities such as QC and Access Services. Work orders are created automatically based on scheduled content and required services.

Meaningful Insights
The analytics engine delivers granular insights that help operations teams spot bottlenecks and improve workflows, including:

• Infrastructure usage across storage, Auto QC, and transcode jobs
• Vendor fulfillment jobs
• VoD and linear platform deliveries

Rule-Based Automation
BRAHMA AI Core enables policy-based archival rules across storage tiers, based on content categories, for smarter and more efficient storage management.

Resilience, Business Continuity, and Disaster Recovery
BRAHMA AI Core provides a resilient disaster recovery backbone, supporting application and content availability across multi-vendor supply chain operations.

6. Next-Generation Media Supply Chain

BRAHMA AI Core worked with Channel 4 to build an optimized next-generation supply chain, combining the right processes, technology, frameworks, tools, and people. Focus areas include:

Content Acquisition
BRAHMA AI Core governs supplier onboarding and lets content providers securely send content through cloud buckets or the platform UI. Business rules determine the automated workflows that follow.

Supplier Trust Level
Suppliers are assigned trust levels that determine how much business validation their content requires.

Validation and Quality Checks
BRAHMA AI Core performs virus checks, content validation, and automated quality checks based on defined business rules.

Content Identification
BRAHMA AI Core automates content identification wherever possible, using information delivered with the video, for example UK DPP productions, commercials, or music videos. When information is insufficient, items are routed to Channel 4's Programme Managers for identification and assignment of the correct Channel 4 ID. Segmentation timecodes and audio track layouts can also be populated automatically.

Content Exchange
BRAHMA AI Core orchestrates secure content exchange between vendors through common interfaces and frameworks. Advanced schedules track vendor tasks and deliverables, giving Channel 4 continuous visibility.

A trusted vendor ecosystem also reduces repeated QC and metadata checks on content that has already been validated.

Powering VOD
BRAHMA AI Core's distribution module automates delivery to Channel 4 Streaming and multiple destinations, including Amazon Prime, YouTube, Virgin Media, Sky On-Demand, SkyGo, Kantar Media, Sound Mouse, and Freewheel.

Based on API triggers and business requirements, BRAHMA AI Core restores content from archive, performs clipping or stitching where required, transcodes, packages, and delivers it. Rendition rationalization lets files be reused across multiple destinations.

7. Automated Media Workflows: Inbound to Outbound

With BRAHMA AI Core, Channel 4's operations are highly automated across three key phases:

Inbound Process
Content providers are onboarded through the BRAHMA AI Core interface or bespoke integrations such as S3 buckets and Aspera endpoints. Once content is received, BRAHMA AI Core automates virus checks, validation, and archiving across cloud and on-premises environments.

Content Identification
BRAHMA AI Core automatically identifies content wherever sufficient information is available. Exceptions are routed to Channel 4's Programme Managers for identification and assignment of the correct Channel 4 ID.

Content QC
Content goes through automated and manual QC based on content type, business rules, and Channel 4 requirements. Review status, progress, and outcomes sync with Channel 4 systems in real time.

Transform, Enrich, Collaborate
Most workflows are automated, with craft editing, new-version creation, defect correction, and Access Services remaining where manual work is required.

When a new version is needed, BRAHMA AI Core automatically manages the restore, delivery, re-ingest, and correct asset identification and hierarchy. Its trusted vendor ecosystem further reduces repeated validation and QC work.

Outbound Process
Outbound transcoding and delivery are fully automated. Following an API or UI request, BRAHMA AI Core restores content from archive, performs clipping or stitching where required, transcodes, packages, and delivers it to linear, streaming, vendor, or ad hoc destinations.

The platform automates high-volume, multi-rendition delivery across Channel 4 Streaming and destinations including Amazon Prime, YouTube, Virgin Media, Sky On-Demand, SkyGo, Kantar Media, Sound Mouse, and Freewheel, letting Channel 4 manage high content volumes, multiple tasks, vendors, and constantly changing deadlines without manual orchestration.
