Building a Scalable OTT Platform: Architecture, Tech Stack & Monetization Models (2025 Guide)

The balance of power in television has tipped. This past May, U.S. viewers spent 44.8% of their TV time on streaming platforms, nudging past the combined total of cable and broadcast for the first time. And it wasn’t a one-month blip – through July and August 2025, streaming’s share held steady at about 46-47%, making clear that traditional TV is now the smaller player in the room.

Financial projections tell the same story of momentum. Research from Grand View values the worldwide OTT sector at nearly $300 billion in 2024, with the U.S. portion alone on track to grow from roughly $62 billion to more than $112 billion by 2029. That’s an annual expansion rate of close to 6% which is a steady, sustained growth in a maturing industry.

This is a clear wake-up call for providers. When millions of people tune in at once, whether for a sports final, a breaking news stream, or a new show premiere, platforms that can’t scale risk lost revenue, churn, and reputational damage. By contrast, companies that prioritize elasticity, smart delivery strategies, and modern OTT monetization models set themselves up for long-term resilience.

Dacast plays directly into this space, helping broadcasters and enterprises scale seamlessly with cloud-based transcoding, secure HLS delivery, and integrated monetization features. In this guide, we’ll break down the architectural layers, OTT tech stack choices, and revenue strategies that define a truly scalable OTT platform in 2025.

Core OTT Architecture (End-to-End)

Building a scalable OTT platform starts with understanding the layers that move content from the creator to the viewer. Each layer, such as ingest, transcoding, storage, delivery, player, and analytics, plays a crucial role in ensuring reliability, performance, and readiness for monetization. Here’s a breakdown of the key components.

  • Churn Risk Monitoring

Ingest Layer

The ingest layer is the entry point for video into your OTT system. Encoders (hardware or software) capture content and transmit it to the platform using protocols like RTMP/RTMPS for traditional live feeds, or SRT for unreliable networks where packet loss and jitter are concerns.

A key distinction is contribution vs distribution: contribution streams originate from studios, mobile units, or remote talent, while distribution streams are optimized for end-user playback. High-quality ingest ensures minimal packet loss and prepares the stream for downstream processing, which directly impacts startup time and rebuffering metrics.

Checklist:

• Use SRT for unstable networks to prevent dropped frames
• Implement redundancy in encoders for high-profile events
• Maintain secure ingest endpoints with token authentication

Transcoding & Packaging

Once the content is ingested, it must be converted into formats that can reach all devices efficiently. Cloud-based transcoding automates this process, generating multiple quality layers in ABR ladder settings for sports streaming (1080p60) or for general content (1080p30).

Packaging uses CMAF, HLS, and DASH standards to create streams compatible with different devices and players. Automated captioning and cue points can also be applied at this stage, and therefore enhance accessibility and interactivity. Dacast supports HLS/DASH packaging and cloud transcoding for OTT, making multi-device delivery seamless.

Checklist:

• Configure the adaptive bitrate (ABR) encoding ladder according to content type
• Enable CMAF for LL-HLS (low-latency HLS) or DASH support
• Integrate captioning for accessibility and engagement

Origin & Storage

The origin layer serves as the central repository for all encoded content, typically on object storage platforms. Origin hardening and origin shield / tiered caching protect your storage from sudden spikes in requests and potential DDoS attacks.

Tokenized access, cache-key strategies, and tiered storage policies help control both performance and security, ensuring that only authorized viewers can access streams.

Checklist:

• Implement secure video delivery with signed URLs or tokenized cookies to control access
• Implement origin shielding to reduce load on primary storage
• Apply intelligent cache keys to optimize CDN efficiency

Delivery / CDN

Content delivery networks (CDNs) distribute your streams to viewers worldwide. Multi-CDN streaming strategies increase reliability, minimize latency, and handle regional traffic fluctuations. Multi-CDN content steering for live events ensures that viewers are routed to the optimal CDN node, improving startup times and reducing buffering.

Additional considerations include tiered caching, egress controls, and modern transport protocols like HTTP/3 and QUIC to optimize performance. Dacast provides multi-CDN integration to streamline this process, which significantly reduces the operational complexity for broadcasters.

Checklist:

• Implement multi-CDN delivery for redundancy and scale
• Enable content steering (HLS/DASH) based on geographic location or real-time health metrics
• Consider HTTP/3/QUIC for improved latency and throughput

Player Technology

The player is the final interface for viewers, and its capabilities directly affect QoE. Modern OTT relies on HTML5 players with support for MSE/EME, LL-HLS for low latency, and WebRTC for sub-second interactivity.

Players must also integrate ad SDKs, subtitle rendering, and accessibility features to meet audience expectations. A flexible, secure player is essential for a hybrid OTT monetization strategy (SVOD + AVOD + TVOD). Dacast’s OTT player (HTML5 video player) supports LL-HLS, DRM, and ad integration, simplifying these requirements.

Checklist:

• Ensure LL-HLS support for low-latency streams
• Include accessibility options (captions, audio descriptions)
• Enable ad and paywall integration within the player

Observability & Analytics

Monitoring and analyzing stream performance is essential for QoE and revenue optimization. This includes player-side metrics (startup time, rebuffer ratio, bitrate) and CDN logs aggregated via CMCD (Common Media Client Data).

Analytics allow operators to detect anomalies, understand user behavior, and correlate QoE metrics with churn risk. For example, Conviva research suggests that even a 1% degradation in QoE can drive a corresponding 1% increase in churn, highlighting the importance of observability.

Checklist:

• Track real-time and historical data
• Use CMCD analytics / QoE metrics for unified insights across CDNs
• Implement dashboards for monitoring and alerting on performance issues

The Modern OTT Tech Stack (Blueprint)

Choosing the right technologies under the hood is what determines whether you can build an OTT service that works and scales efficiently while keeping viewers engaged. Protocols, codecs, latency approaches, AI, and data all fit together into a toolkit that’s constantly evolving. Here’s how each element fits into the 2025 OTT platform infrastructure blueprint.

Protocols & Formats

Protocols are the backbone of video transport. Here’s how ingest vs playback protocols (RTMP/SRT vs HLS/DASH) compare in a nutshell.

For ingest, RTMPS remains the workhorse for traditional workflows, while SRT is increasingly preferred when you need reliability, especially for remote contribution or live events where you have fluctuating network conditions.

HLS and DASH dominate on the playback side, with CMAF acting as the glue that reduces storage and enables cross-compatibility. WebRTC provides sub-second glass-to-glass latency that no other protocol currently matches for use cases like live auctions, betting, or real-time interactivity.

The choice here isn’t just about compatibility, but more about alignment with your use case. You can use HLS/DASH for scale, WebRTC for immediacy, or SRT for resilience.

Checklist: 

• Use SRT for remote or unstable contribution feeds
• Standardize on HLS/DASH with CMAF packaging for scalable playback
• Apply WebRTC only where interactivity demands sub-second response

Codecs

Video codecs balance efficiency vs. reach. H.264 (AVC) still accounts for the majority of streams because it works everywhere, from the cheapest Android phone to smart TVs. But for higher resolutions, especially 4K sports or cinematic content, HEVC (H.265) delivers 30-50% better compression at the same quality.

Then there’s AV1, which is royalty-free and highly efficient but not yet universally supported. Major platforms (YouTube, Netflix, Chrome, Android) are pushing adoption, which means AV1 is quickly moving from “future” to “now.” Still, you need to have fallback strategies.

The smartest OTT operators run multi-codec workflows, serving H.264 for baseline compatibility while gradually introducing HEVC and AV1 where devices can handle them, optimizing both costs and quality.

Checklist: 

• Default to H.264 for universal reach
• Layer in HEVC/AV1 for 4K or bandwidth-sensitive delivery
• Test device coverage before making AV1 your default

Latency Options

Latency is one of the most visible aspects of viewer experience. Standard HLS streams typically run at a 15–30 second delay, which is fine for VOD or casual live content, but problematic when social feeds or second screens spoil the action. LL-HLS (low-latency HLS) trims this to the 3–10 second range, which is now the sweet spot for sports and live entertainment.

When comparing LL-HLS vs WebRTC for low-latency OTT, consider that WebRTC offers sub-second delivery for true interactivity, but real-time streaming at scale with millions of concurrent viewers is costly and technically challenging. 

The trade-off is always scale vs. immediacy vs. cost – there’s no single best option. A hybrid model is often best: LL-HLS for large audiences, and WebRTC streaming for smaller interactive cohorts like commentators or betting participants.

Checklist:

• Define target latency per content type (e.g., sports vs. concerts vs. talk shows)
• Balance audience size against infrastructure cost
• Monitor network conditions continuously to maintain chosen latency levels

AI in the Stack

Artificial intelligence is gaining momentum in video workflows. Automated captioning improves accessibility and compliance while reducing manual costs. Quality control (QC) tools use AI to detect artifacts and optimize encoding, sometimes frame by frame, to reduce bitrate without sacrificing quality.

When it comes to personalized recommendations for OTT, AI-driven recommendation engines improve retention by tailoring content discovery. At the operational level, anomaly detection systems flag sudden spikes in errors, while churn prediction models identify at-risk subscribers early.

Forward-looking OTT platforms are already feeding AI into encoding pipelines, user interfaces, and customer analytics simultaneously, creating a stack that efficiently delivers video and adapts in real time.

Data & Telemetry

Data is the nervous system of OTT in 2025. Standards like CMCD (Common Media Client Data) finally give operators consistent, player-side telemetry on buffering, bitrate shifts, and startup times. Paired with real-user monitoring, this provides a unified view across devices and geographies.

The real power comes from feedback loops: feeding telemetry back into ABR decision-making, CDN routing, or even churn-prevention campaigns. If a segment of users constantly drops quality in a certain region, the system can steer them to a healthier CDN or preemptively adjust the encoding ladder.

Checklist: 

• Standardize on CMCD/QoE metrics across all players
• Implement real-user monitoring for ground-truth visibility
• Build closed feedback loops into ABR and CDN routing logic

Scaling Considerations (From 1,000 → 1,000,000+)

Building a clean OTT architecture is only half the battle. You need to learn how to scale an OTT platform in 2025. The real test comes when your platform shifts from serving a few thousand concurrent viewers to handling millions during a major live event. At this scale, bottlenecks that seemed minor become existential. Here’s how successful operators plan for massive growth without sacrificing quality.

Multi-CDN & Content Steering

No single CDN can guarantee flawless global delivery at all times. Outages, congestion, or even regional spikes can cause buffering if you rely on just one provider. That’s why modern OTT services adopt multi-CDN delivery, which blends multiple networks into a unified strategy.

You can make this more practical with content steering. Methods range from DNS-based routing, which directs users at the domain level, to manifest manipulation, where the player itself fetches the optimal CDN, to real-time API-driven steering for fine-grained, health-based adjustments.

Regional traffic shaping ensures that European viewers, for example, aren’t routed halfway across the world if a local node can serve them faster. The end goal is to achieve resilience and reduce the startup time, no matter where the audience is or how many join at once.

Checklist: 

• Implement multi-CDN delivery to avoid single points of failure
• Use real-time content steering to route viewers to the best node
• Shape traffic regionally for optimal performance

Caching Strategy & Origin Protection

Your origin server is the vault that holds your content, but it’s not designed to handle millions of direct requests. That’s why you need to have a caching strategy. When you set smart TTLs (time-to-live) and pre-warming caches ahead of premieres, you can keep CDNs primed and ready.

If you don’t have safeguards, a sudden surge of users hitting your origin at once (the so-called “thundering herd problem”) can overload your storage and knock all streams offline. Techniques like origin shielding, tiered caching, and tokenized requests ensure the origin only serves what’s absolutely necessary, while CDNs handle the bulk of the load.

Checklist: 

• Set TTLs based on content lifecycle (longer for VOD, shorter for live)
• Pre-warm caches before major live premieres
• Use origin shielding and tiered caching to protect storage

Capacity Planning & Load Testing

Scaling doesn’t mean you just need to buy more servers. You actually need to know what kind of load you’ll face and test against it before real users do. Concurrency modeling can help you estimate peak demand by factoring in geography, device types, and viewing patterns.

Then, use load testing to validate those assumptions. Synthetic tests simulate thousands of users hitting your platform at once, while real-user monitoring (RUM) reveals how actual viewers experience load across devices and networks. Running both ensures your infrastructure isn’t just spec-ready but real-world ready. Don’t be one of the operators who skip this step only to discover weaknesses mid-event when it’s too late.

Checklist: 

• Model concurrency with realistic traffic patterns
• Run synthetic load tests well before major events
• Combine with RUM for ground-truth validation

QoE Engineering

Viewer satisfaction is measured in milliseconds when you’re working at a massive scale. Even a slight increase in startup delay or rebuffer ratio can cause spikes in churn and revenue loss. That’s why large-scale platforms invest in player analytics and QoE (startup time, rebuffer ratio), setting measurable targets while constantly tuning the system to hit them.

Standards like CMCD now make it possible to unify player-side telemetry with CDN-side logs, creating a full picture of how streams perform across millions of viewers. These insights guide adaptive bitrate tuning, CDN routing, and error recovery in real time.

Checklist:

• Define baseline metrics for startup time, rebuffer ratio, and bitrate
• Implement CMCD for unified telemetry across CDNs and players
• Continuously adjust ABR ladders and CDN steering based on QoE data

Global Delivery & China

Scaling globally also introduces regulatory complexity. China, in particular, requires ICP (Internet Content Provider) licensing for lawful delivery, and non-compliant streams risk being blocked outright. Beyond licensing, DNS resolution inside China often behaves differently, requiring localized infrastructure and partnerships.

Other regions also impose compliance rules, from GDPR in Europe to local content restrictions in parts of Asia and the Middle East. Successful OTT platforms plan global delivery not just around CDN coverage, but also around lawful routing strategies and data governance.

Checklist: 

• Audit CDN coverage across all target markets
• Pre-warm caches before global live events
• Ensure China video delivery / ICP compliance
• Adjust DNS and routing strategies for lawful delivery

Monetization Models (SVOD, AVOD/FAST, TVOD, Hybrid)

A scalable OTT platform turns your reach into sustainable revenue. However, the right monetization strategy depends on audience behavior, content type, and long-term business goals. In 2025, providers mix and match subscription, ad-supported, and transactional approaches, often in hybrid forms. Here’s how each model plays out in practice.

SVOD

Revenue: Recurring subscriptions
Friction: Low (after signup, unlimited access)
Tech: Paywall, DRM, billing
Use Case: Ongoing loyalty (series, sports, education)
Examples: Netflix, Max, Disney+

AVOD

Revenue: Advertising (pre/mid-roll, programmatic)
Friction: Medium (ads interrupt but free)
Tech: Ad server, SSAI/CSAI, targeting
Use Case: Mass reach, casual viewers, discovery
Examples: YouTube, Pluto TV, Tubi

TVOD

Revenue: One-time payments (rentals, PPV)
Friction: High (pay for each asset)
Tech: PPV paywall, DRM, billing
Use Case: Premium exclusives, live events
Examples: iTunes, Google TV, UFC PPV

Hybrid

Revenue: Mix of subs + ads + PPV
Friction: Variable (depends on mix)
Tech: Full stack (subs, ads, PPV)
Use Case: Flexibility, scale + niche
Examples: Hulu, Peacock, Amazon Prime Video

SVOD (Subscription Video on Demand)

The most familiar model is one where viewers pay a recurring fee for unlimited access to a library or channel. SVOD thrives when there’s a steady stream of new or evergreen content to justify ongoing payment.

Pricing strategy is critical, so many platforms experiment with tiered subscriptions (basic vs premium), bundling with other services, or annual discounts to reduce churn. Churn mitigation is the central challenge here, as data indicates that gross SVOD churn is around 5.3% as of late 2024, a figure that pressures providers to keep audiences engaged.

Retention tactics include personalized recommendations, loyalty perks, and proactive engagement when user activity dips.

Checklist: 

• Offer multiple tiers (e.g., mobile-only, family plan, premium 4K)
• Use annual plans or bundles to reduce churn risk
• Track churn triggers (inactivity, price sensitivity)

AVOD / FAST (Ad-Supported Video on Demand & Free Ad-Supported TV)

Ad-supported streaming has surged in popularity, especially on connected TVs. The appeal for viewers is obvious: free content, no credit card required. The challenge for operators is ad quality and fill rate.

Modern OTT relies on FAST channels / SSAI. SSAI (Server-Side Ad Insertion) stitches ads directly into the stream, bypassing ad blockers and improving playback smoothness. By contrast, client-side tags are easier to implement but more prone to buffering and ad-block disruption.

FAST channels (linear-style ad-supported streams) are growing quickly and giving platforms new ways to repurpose content and expand inventory. They help ensure brand safety and optimize programmatic ad demand.

Checklist:

• Implement SSAI for seamless ad playback
• Monitor fill rates and optimize demand sources
• Enforce brand safety and quality controls
• Explore FAST channels for 24/7 ad-supported reach

TVOD (Transactional Video on Demand)

In the pay-per-view (PPV) or TVOD model, viewers pay individually for specific content such as a fight night, concert, or film premiere. This model shines when content has scarcity, urgency, or strong fan loyalty.

Effective tactics include windowing (limited release before SVOD/AVOD availability), pre-orders (locking in revenue before release), and bundles (e.g., discounted packages of multiple events). While TVOD revenue can be less predictable, margins per title are often higher than with subscriptions.

Checklist: 

• Enable pre-orders for predictable early revenue
• Use windowing to maximize exclusivity value
• Offer bundles to increase average transaction size

Hybrid Playbooks

The most resilient OTT platforms combine models. For example:

• A core SVOD library, with occasional TVOD premieres for blockbuster content.
• A free ad-supported tier (AVOD/FAST) to widen funnel reach, with upsell flows to subscription.
• In-player upsells, where a user watching an ad-supported stream can instantly upgrade to ad-free.

This flexibility helps balance revenue diversification with user choice. Hybrids also open the door to personalization, like tailoring offers based on user cohorts, geography, or device.

Checklist: 

• Design upgrade paths from free to paid tiers
• Test in-player upsells and cross-model bundles
• Monitor performance of mixed-model flows

Analytics for Revenue

Revenue doesn’t scale without measurement. Platforms need granular data on LTV (lifetime value), ARPU (average revenue per user), ad yield (fill rates, eCPM), and cohort retention.

For SVOD, this means understanding churn drivers at a segment level. For AVOD/FAST, it’s about maximizing ad impressions without degrading QoE. For TVOD, operators must track conversion rates and optimize promotional timing.

Modern platforms now integrate real-time dashboards that unify payment, engagement, and ad data. This makes it possible to quickly spot underperforming content, forecast revenue, and fine-tune pricing strategies.

Dacast simplifies much of this with built-in paywall and ad tag integrations, supporting SVOD, TVOD, and AVOD workflows. The platform also provides analytics to track performance across models, so we recommend exploring more of Dacast’s video monetization features.

Checklist: 

• Track LTV and ARPU to guide pricing
• Monitor ad metrics (eCPM, fill, ad-pod QoE)
• Run cohort analysis to pinpoint churn risks
• Feed analytics back into pricing and ad strategies

Monetization Launch (Summary Checklist)

Before flipping the switch on revenue, it’s worth validating the essentials. These steps ensure your chosen models actually work in practice, that payment and ad flows won’t break at scale, and that you can measure success from day one.

• Select model(s) aligned with your content and audience
• Implement SSAI for ad-supported streams
• Test payment and ad flows across devices
• Track churn, retention, and yield KPIs regularly

Security & Compliance

Security is no longer a back-office checkbox, and now it’s a frontline requirement for a scalable OTT platform. Piracy, credential abuse, and data privacy concerns can erode revenue and trust faster than most operators anticipate. A well-architected OTT platform needs to balance accessibility with strict controls, ensuring both viewers and rights holders are protected.

Access Control & DRM

The first line of defense is access control. Tokenized URLs and signed cookies limit viewing to authorized users, preventing unauthorized sharing of links across forums or social platforms. On top of that, premium or licensed content nearly always requires digital rights management (DRM).

Major standards in OTT DRM (Widevine, FairPlay, PlayReady) are widely supported across devices, ensuring both compliance with content licensing deals and a smooth playback experience for end users.

Dacast is here to help with OTT DRM and watermarking best practices, offering secure video delivery with signed URLs and removing much of the technical burden from publishers.

Anti-Piracy

Piracy remains a real threat, even with DRM. Streams can be re-captured, credentials shared among dozens of users, or unauthorized restreams broadcast on gray-market platforms. To combat this, forensic watermarking embeds invisible identifiers within the video and makes it possible to trace leaks back to the source. This acts as a deterrent but also provides concrete evidence if legal action is required.

Mitigation strategies also extend to credential sharing controls, such as limiting concurrent logins, monitoring suspicious usage patterns, and applying device caps. These safeguards are essential to protect both revenues and licensing agreements.

Privacy & Compliance

Beyond content protection, platforms must adhere to data protection laws and industry compliance standards. GDPR (for EU audiences) and SOC 2 (for enterprise-grade security audits) set the bar for responsible data handling. Operators need mechanisms for explicit consent collection, granular user controls, and full audit logging of who accessed what, and when.

Compliance will help you avoid fines, but it directly impacts user trust. Viewers are more willing to subscribe or share data when they believe their information is secure and handled transparently.

Security Setup Checklist

To put these security and compliance principles into action, consider implementing the following key measures across your OTT platform. These steps cover content protection, access control, and regulatory compliance.

• Deploy DRM for premium and licensed content
• Enable geo/IP restrictions where distribution rights require it
• Implement secure video delivery with signed URLs or cookies
• Monitor for piracy signals and credential abuse
• Maintain audit logs and consent workflows for GDPR/SOC 2

Build vs. Buy: What to Outsource

The OTT platform build vs buy decision is one of the most strategic choices a streaming operation can make. It’s not just about cost – it’s about speed, expertise, operational risk, and the ability to scale reliably. While some organizations have the resources to handle every layer themselves, most find that a hybrid approach works best, so they are outsourcing specific components and looking for the optimal balance of control and efficiency.

Decision Criteria

When evaluating build vs. buy, consider several critical factors:

• Time-to-Market: Building from scratch requires months (sometimes years) of development, testing, and integration. Using a managed platform like Dacast accelerates deployment, allowing broadcasters to go live quickly without compromising quality.
• Total Cost of Ownership (TCO): Beyond initial development, consider ongoing costs for server infrastructure, maintenance, security, licensing, and staffing. Managed solutions can often reduce these recurring expenses while providing predictable pricing.
• Expertise: In-house teams must be skilled in video encoding, CDN integration, DRM, multi-device playback, and monetization workflows. Outsourcing to a platform with built-in capabilities can fill gaps in technical expertise.
• Operational Coverage: Handling live events, scaling to millions of concurrent viewers, and ensuring 24/7 uptime can strain internal teams. Managed platforms offer built-in reliability, monitoring, and support to mitigate these risks.

Where Dacast Reduces Complexity

• Cloud-based transcoding and adaptive bitrate delivery
• Multi-CDN content steering and global distribution
• Secure playback with DRM and tokenized URLs
• Integrated monetization features for SVOD, AVOD, and TVOD
• Analytics dashboards and QoE monitoring

This allows internal teams to focus on content strategy, audience growth, and monetization rather than infrastructure headaches.

Checklist: Build vs. Buy

Here are a few boxes you should check in the process:

• Assess internal expertise across encoding, CDN, DRM, and player integration
• Compare TCO and ongoing operational costs vs. a managed platform
• Decide which layers (ingest, transcoding, storage, CDN, player, monetization) to outsource
• Evaluate support and SLA commitments from your provider

Case Studies / Patterns 

Every vertical has unique requirements when it comes to OTT. Understanding these patterns helps broadcasters and enterprises design architectures that align with audience expectations, peak demand, and monetization goals. Below are four illustrative examples showing how different sectors approach OTT deployment, along with the architecture choices and KPIs that matter most.

FAQs

1. What’s the difference between ingest and playback protocols?

Ingest protocols (like RTMP, RTMPS, SRT) handle how content enters your OTT platform from cameras, studios, or remote contributors. Playback protocols (HLS, DASH, LL-HLS, WebRTC) control how content is delivered to end-user devices. A clear distinction ensures optimal stream quality and latency at both ends. Dacast supports both, simplifying the end-to-end workflow.

2. LL-HLS vs WebRTC: when to use which?

LL-HLS is ideal for live streaming events where 2–5 second latency is acceptable and scale is important. WebRTC is best for ultra-low-latency scenarios (sub-second) such as live auctions, sports betting, or interactive broadcasts. Many OTT services combine both to balance interactivity and scalability. Dacast supports both protocols, letting operators choose per use case.

3. How do I choose a codec ladder in 2025?

Choose codecs and ABR ladder settings based on content type, device diversity, and bandwidth expectations. H.264 offers broad device compatibility and it’s reliable for general-purpose streams. HEVC/AV1 is efficient for 4K and high-motion content, but has limited device support.

An ABR ladder should include multiple resolutions and bitrates to maintain QoE across networks. Dacast’s cloud transcoding automates and optimizes these settings.

4. What’s CMCD, and why does it matter for QoE?

CMCD (Common Media Client Data) standardizes telemetry across players and CDNs. It feeds adaptive bitrate decisions, monitors buffering and startup times, and correlates QoE metrics with churn. Implementing CMCD helps operators deliver smoother playback and reduces subscriber loss.

5. How do I implement SVOD vs AVOD vs TVOD on one platform?

Hybrid monetization lets platforms offer subscriptions, ad-supported content, and pay-per-view simultaneously. The key is integration: ad tags for AVOD, subscription/paywall management for SVOD, and one-off purchases for TVOD. Dacast supports all three monetization models in a single platform, streamlining hybrid workflows.

6. How does Dacast support monetization and security for OTT?

Dacast provides:

• Built-in paywalls and ad tag integrations for SVOD, AVOD, and TVOD.
• Secure video delivery via tokenized URLs, signed cookies, and DRM (Widevine, FairPlay, PlayReady).
• Multi-CDN delivery and content steering for scale and performance.
