OTT glossary – Explaining Each Term
What Is a Linear Channel?
A linear channel refers to the traditional TV model in which content is broadcast according to a fixed schedule. Viewers cannot rewind or choose what’s playing—they simply tune in to watch the real-time broadcast stream.
For example, cable and satellite TV channels like VTV, HTV, K+, or Fox Sports are Linear Channels.
What Is an OTT Linear Channel?
An OTT linear channel is a linear TV model delivered over the internet, rather than via cable or satellite. The content follows a set schedule, just like a traditional linear channel, but it’s accessible on OTT apps, Smart TVs, websites, or mobile devices.
Examples: Popular OTT Linear Channels include VieON Live TV, FPT Play Live, and VTV Go.
Strengths of OTT Linear Channels:
- No dependency on cable or satellite infrastructure.
- Flexible monetization options like SVOD (Subscription Video on Demand), TVOD (Transactional Video on Demand), or AVOD (Advertising Video on Demand).
- Ideal for the best OTT platforms aiming to preserve a “traditional TV” experience.

What Is a Live Linear Channel?
A live linear channel is an OTT linear channel that includes live broadcasts. The content follows a schedule but may feature real-time events such as sports, news, or live TV shows.
Examples: Live news channels like CNN Live, BBC Live, VTV24, or live sports channels.
Strengths of Live Linear Channels:
- Delivers a “live TV” feel, even on OTT platforms.
- Highly engaging for content like news, sports, and reality entertainment.
- Leverages real-time advertising, especially with SSAI (Server-Side Ad Insertion).

What Is a FAST Channel?
FAST (Free Ad-Supported Streaming Television) Channels are free-to-watch, scheduled TV channels that operate entirely on OTT platforms. The key distinction of FAST Channels lies in their use of dynamic advertising through SSAI (Server-Side Ad Insertion) technology, rather than traditional ad insertion methods like CSAI (Client-Side Ad Insertion).
In short, a FAST Channel is an OTT Linear Channel powered by SSAI advertising. However, simply saying “FAST Channel = OTT Linear Channel + SSAI” doesn’t tell the whole story. To qualify as a FAST Channel, it must meet specific criteria:
- Free for viewers (Free).
- Revenue generated through ads (Ad-Supported).
- Exists solely on OTT platforms (Streaming Television).
- Operates like traditional TV with a fixed broadcast schedule.
That said, not every OTT Linear Channel with ads qualifies as a FAST Channel. Here are some exceptions:
Case 1: HBO or Disney+ as OTT Linear Channels with paid subscriptions and sponsor ads.
These aren’t FAST Channels because:
- Viewers pay a subscription fee, so it’s not “Free.”
- Sponsor ads are static and not dynamically delivered via SSAI.
This falls under “Subscription-Based OTT Linear Channels” or “Premium Linear Channels.”
Example: A sports program on ESPN+ with a “Coca-Cola sponsors this match” ad isn’t FAST—it’s not free, and the ads aren’t personalized.
Case 2: HBO or Disney+ as OTT Linear Channels with paid subscriptions and SSAI dynamic ads.
This case is still not a FAST Channel because:
- Despite using SSAI, viewers must pay to access the content.
- FAST Channels must be completely free to attract a large audience, relying solely on ad revenue.
Example: If Disney+ streams a 24/7 Marvel channel with SSAI ads but requires a subscription, it’s not a FAST Channel.
