Streaming Model
VOD (Video on Demand)
Last updated: December 23, 2025
VOD (Video on Demand) is a streaming model where viewers access video content on their own schedule rather than watching a live or scheduled broadcast. It is the foundational delivery model behind SVOD, AVOD, and TVOD — and the core content experience on every OTT platform.

What it is
VOD (Video on Demand) is a content delivery model where video is stored and made available for viewers to watch at any time — on any device, without a broadcast schedule. It is the foundational content model of every OTT platform, enabling personalized, on-demand streaming experiences at scale.
- Content is stored and streamed on request — no scheduled broadcast required.
- Delivered via CDN using adaptive bitrate streaming (HLS or DASH).
- Supports multiple monetization models: SVOD, AVOD, TVOD, and hybrid.
- Enables personalization, recommendations, and continue watching features.
- OTT and VOD are related but distinct — OTT is how content is delivered, VOD is the content model.
- Broadcast VOD (BVOD) is a variant where traditional broadcasters make content available on-demand after its scheduled airdate.
Why it matters
VOD is what made streaming viable as a consumer habit. By removing the constraint of scheduled broadcasting, it gave viewers full control — watch what you want, when you want, on the device you choose. For OTT operators, VOD is the core content experience that everything else is built around: personalization, recommendations, continue watching, and entitlement management all exist to serve a VOD catalog. The business models that power OTT — SVOD, AVOD, and TVOD — are all variations of how a VOD library is monetized. Understanding VOD is understanding the foundation of modern streaming.

- There are three main VOD monetization models: SVOD, AVOD, and TVOD.
- VOD content is stored on CDNs and delivered via adaptive bitrate streaming (HLS/DASH).

- VOD enables personalization, recommendations, and continue watching features.
- Broadcast VOD (BVOD) is a variant where traditional broadcasters make their content available on-demand.
How it works
1
Ingest
Content is uploaded into the platform's CMS and transcoded into HLS/DASH streaming formats with multiple quality renditions.
2
Store
Transcoded assets are stored on a CDN — distributed across edge nodes globally for low-latency retrieval.
3
Protect
DRM is applied to secure content against unauthorized access and piracy before delivery.
4
Entitle
When a viewer selects a title, the platform checks their entitlement — subscription tier, purchase history, or ad eligibility.
5
Stream
The CDN serves the stream to the viewer's device. Adaptive bitrate playback adjusts quality in real time to available bandwidth.
6
Measure
Playback events — start, pause, completion, drop-off — are logged in analytics to inform content and product decisions.

Key variations
SVOD — Subscription VOD
Viewers pay a recurring subscription fee for unlimited access to the VOD library. The dominant model for OTT platforms globally.
AVOD — Ad-Supported VOD
Content is free to viewers, funded by advertising revenue inserted into the stream via SSAI or CSAI.
TVOD — Transactional VOD
Viewers pay per title, season, or rental — pay-as-you-go access with no ongoing subscription required.
BVOD — Broadcast VOD
Traditional broadcasters make their scheduled content available on-demand after broadcast — catch-up TV is the most common form.
Real-world example
A broadcaster extending linear TV with a VOD library
A national broadcaster with strong live and scheduled TV viewership wants to retain younger audiences who are shifting to on-demand consumption and cancelling traditional TV subscriptions.
Challenge
- Younger viewers are not watching scheduled broadcasts and expect on-demand access.
- The broadcaster has a large archive of content that generates no revenue after its broadcast window.
- Competitors are growing VOD libraries rapidly, drawing the broadcaster's audience away.
- No infrastructure exists to deliver, manage, or monetize content on demand.
Action taken
- Launched a VOD platform using an OTT solution alongside their existing linear broadcast.
- Ingested their full content archive and made it available on demand via SVOD subscription.
- Added an AVOD tier for free access to older content, funded by programmatic advertising.
- Implemented continue watching, recommendations, and personalized home screens.
- Connected VOD analytics to track completion rates, drop-off points, and most-watched titles.
Outcome
The broadcaster retained 34% of at-risk younger subscribers, generated new AVOD revenue from archive content that previously earned nothing post-broadcast, and grew their direct subscriber base by 2.1x within a year.
FAQs
What does VOD stand for?
VOD stands for Video on Demand — a content delivery model where viewers can watch video content at any time they choose, rather than at a scheduled broadcast time.
What is the difference between OTT and VOD?
OTT (Over-The-Top) refers to how content is distributed — over the internet without cable or satellite. VOD refers to the content model — on-demand access rather than scheduled broadcasting. OTT platforms typically deliver VOD content, but they can also deliver live streams. VOD can also be delivered via cable systems. They describe different things that frequently go together.
What are the types of VOD?
The three main types are SVOD (Subscription Video on Demand — e.g. Netflix), AVOD (Ad-Supported Video on Demand — e.g. Pluto TV), and TVOD (Transactional Video on Demand — pay per title or rental). Many OTT platforms combine two or more models in a hybrid approach.
What is broadcast VOD?
Broadcast VOD (BVOD) is a model where traditional TV broadcasters make their content available on-demand after its scheduled broadcast. Viewers can catch up on missed episodes or rewatch programmes through the broadcaster's own streaming app or website.
What does VOD mean on YouTube?
On YouTube, VOD refers to pre-recorded video content available to watch at any time — as opposed to a YouTube Live stream. Any uploaded video on YouTube is technically a VOD asset.
