What Is VOD? Video on Demand Explained (SVOD, AVOD, TVOD)

VOD, or video on demand, is video you choose and start whenever you want — films, series and recorded shows you can pause, rewind and resume — instead of watching at a time set by a broadcaster. Netflix, broadcaster catch-up apps and the movie section of an IPTV service are all VOD.

The term is simple, but VOD services make money in different ways, which affects what you pay and whether you see adverts. This guide explains the meaning of VOD, the main business models, how ad-free and ad-supported streaming services compare, and how VOD fits into IPTV.

VOD vs live (linear) TV

Many services now blend both: live channels with catch-up, or VOD apps with a few scheduled channels. The Wikipedia article on video on demand (opens in a new tab) covers the history.

The meaning of "VODs" in streaming communities

On live-streaming platforms, people talk about "VODs" — plural — to mean recordings of past live broadcasts. A streamer's VODs are their earlier streams, saved for viewers to watch later. It's the same concept: something originally live, now available on demand.

The main VOD business models

SVOD — subscription video on demand

You pay a recurring fee for unlimited access to a library. Most large streaming platforms work this way. Many now offer several tiers, from an ad-supported plan to premium ad-free plans with higher resolution.

AVOD — advertising-based video on demand

You watch free and adverts pay for it. Ad-supported streaming services have grown quickly because they cost viewers nothing. Libraries are often older or more niche, but there's a lot to choose from.

TVOD — transactional video on demand

You pay per title: rent a film for a limited time or buy it to keep in a digital library. This suits viewers who watch occasionally and don't want another subscription. Premium VOD (PVOD) is a higher-priced rental of new releases.

FAST — a close relative

Free ad-supported streaming TV offers scheduled channels rather than on-demand titles, so it's technically linear rather than VOD. It often sits alongside AVOD in the same apps. See what FAST channels are.

Ad-free vs ad-supported streaming services

Choosing between an ad free streaming service and ad supported streaming services comes down to time, money and how you watch.

Ad-free makes sense if you watch a lot, hate interruptions, or watch with children and want control over what appears between programmes.

Ad-supported makes sense if you watch occasionally, want to cut costs, or already pay for one main service and want variety on top.

A sensible approach for many households is one paid SVOD service at a time, rotated every few months, plus free AVOD and FAST apps for variety.

VOD terms you'll come across

• Catch-up: recently broadcast programmes available on demand for a limited time.
• Box set: a complete series or several seasons released together.
• Download to go: saving titles to a phone or tablet to watch offline, where the service allows it.
• Windowing: the order in which a film reaches cinemas, rental, subscription and free platforms.
• PVOD: premium rentals of new releases, priced above ordinary rentals.

How VOD is delivered

VOD titles are stored on servers and delivered on request, usually through content delivery networks. Players use adaptive streaming — formats like HLS (described in RFC 8216 (opens in a new tab)) — which switch between quality levels as your connection changes. Because the whole file exists in advance, VOD can buffer further ahead than live TV, which is why on-demand films often play more smoothly than live channels on the same connection.

VOD in IPTV services

Many IPTV services include a VOD section next to live channels. When comparing them, check:

• Organisation. Are films and series grouped by genre, year and language?
• Search. Can you find a title quickly with a TV remote?
• Series handling. Are seasons and episodes in order, and does the player remember where you stopped?
• Subtitles and audio tracks. Are languages labelled clearly?
• Quality. Do titles play at the resolution claimed?

Your player app affects much of this; see our guide to IPTV players. For a broader explanation of what IPTV services include, read IPTV service explained.

Data and quality considerations

VOD uses the same bandwidth as live streams at the same quality. As a rough guide, Netflix recommends about 5 Mbps for Full HD and 15 Mbps for 4K (Netflix Help Center (opens in a new tab)). If your broadband has a data cap, watching in HD rather than 4K saves a lot of data over a month.

Watching VOD offline and on the move

Some services allow downloads to phones and tablets for offline viewing, which is ideal for travel. Downloads usually expire after a set period and need the app to reconnect occasionally to stay valid. Live channels can't be downloaded this way.

Choosing a VOD setup

1. List what you actually watched last month.
2. Decide which titles need a paid service and which can come from free sources.
3. Prefer monthly plans you can pause or rotate.
4. Check device support on every screen you use.
5. Revisit every few months — libraries change.

VOD with XCode IPTV 8K

XCode IPTV 8K includes an on-demand library of films and series alongside live channels, with 4K, UHD, FHD and HD options where available. You can browse it during the free 24-hour trial and see what's included on the features page.

Summary

VOD means video you start on your own schedule. It comes in several models — subscription (SVOD), ad-supported (AVOD), and pay-per-title (TVOD) — each suited to different viewers and budgets. Ad-free plans trade money for convenience; ad-supported options trade a few interruptions for a lower bill. In IPTV, a well-organised VOD library is a big part of everyday value, so test it before you choose.
