Linear TV vs CTV vs OTT in India: What Does DV360 Actually Buy?

The television screen does not decide whether an ad is Linear TV or Connected TV. The delivery route, viewing environment, buying method and measurement source do.

A television receiving content through separate broadcast and internet delivery paths
One screen can carry both broadcast television and internet-delivered streaming. The path changes the advertising system.

A smart television is not automatically Connected TV advertising.

If you watch Star Plus through a cable or DTH connection on a smart television, you are watching Linear TV. If you open JioHotstar, YouTube, SonyLIV or another streaming app on the same television through the internet, you are in a Connected TV environment.

If you watch the same streaming service on a mobile phone, it remains OTT or digital video, but it is not CTV because the viewing device is not a television.

The simplest rule: the screen alone does not define the media. First identify how the content arrived, where it was watched and how the advertising was purchased.

Why this distinction matters now

India’s television market is currently dealing with two separate developments: the continuing BARC television-ratings blackout and the repeal of the earlier 12-minute-per-clock-hour advertising ceiling for television channels. These developments concern the traditional television ecosystem, its audience currency and the flexibility available to broadcasters. BARC ratings update · Advertising-duration update

At the same time, marketers increasingly discuss CTV, OTT and Display & Video 360 (DV360) as though every advertisement appearing on a television screen belongs to the same buying system. It does not.

A conventional Star Plus broadcast slot and a targeted video impression inside an internet-connected streaming app may appear on the same physical television. But they can involve different sellers, buying routes, targeting options, reporting systems and standards of evidence.

What is Linear TV?

Linear TV is traditional scheduled television delivered through a broadcast, cable or Direct-to-Home (DTH) service. The viewer watches programmes according to the channel’s schedule.

Examples include watching Star Plus, Zee News or NDTV through Tata Play, Airtel Digital TV, Dish TV or a local cable operator. The television itself may be smart or non-smart; that does not change the delivery into CTV.

Advertising slots are typically negotiated through broadcasters, television networks, media agencies or specialist television-buying partners. The buy may be organised around channels, programmes, genres, dayparts, spot lengths, markets and expected ratings.

What is Connected TV?

Connected TV describes television viewing in which video content reaches the television through an internet connection. Google defines CTV as television sets used to stream internet-delivered video, including smart TVs, streaming devices, connected set-top boxes and gaming consoles.

A television can become part of a connected environment through:

CTV therefore refers to the internet-connected television viewing environment, not one manufacturer, streaming service or advertising platform.

What is OTT, and why is it not the same as CTV?

OTT means video content delivered “over the top” of traditional cable or satellite distribution through the internet. It describes the delivery of content, not necessarily the screen on which it is watched.

JioHotstar on a smart televisionYesYesInternet-delivered content viewed on a television

Star Plus through Tata PlayNoNoScheduled channel feed delivered through DTH
Star Plus live inside an internet streaming app on TVYesYesThe programme may be live, but delivery is internet-based and the device is a TV

“Live” does not automatically mean Linear TV. A live channel or sporting event streamed through an internet app can still be OTT and, when watched on a television, CTV.

What does DV360 actually buy?

DV360 is Google’s enterprise platform for planning, buying, managing and measuring digital media. Its Connected TV workflow is designed for digital television and OTT inventory available through eligible publishers, exchanges and deals.

Google describes CTV insertion orders as a workflow for buying television and OTT content on connected-TV devices. Depending on availability, advertisers may use curated CTV auction inventory, publisher deals, Programmatic Guaranteed arrangements or YouTube & partners on CTV. Connected TV insertion orders · Connected TV line items

In practical Indian media planning, this means DV360 can be used to buy eligible internet-delivered CTV and OTT impressions. A conventional advertisement appearing inside the normal Star Plus cable or DTH feed is not automatically purchased through a standard DV360 CTV line item.

Why does DV360 mention Linear TV?

This is where planning and buying are frequently confused.

DV360 includes tools that can compare estimated reach and frequency across digital media and Linear TV in supported markets. Google’s documentation states that these plans use historical television data and measurement providers to compare Linear TV with YouTube, third-party video and CTV.

That does not mean every Linear TV spot in every market can be purchased through a normal DV360 digital line item. Google’s published support list for Linear TV and digital planning currently names the United States, Japan, Vietnam, France and Germany—not India. Source: Google

Planning is not buying. A platform may use television data to forecast or compare media without serving the underlying broadcast advertisement itself.

What can DV360 report for CTV?

For eligible CTV activity, DV360 can provide digital delivery signals such as impressions, device type, app or inventory identifiers, estimated unique reach, frequency and campaign-level performance reporting. Google also provides co-viewing-adjusted reach estimates because multiple people may watch the same television. CTV reporting and forecasting · Co-viewing measurement

Where the advertiser’s measurement setup and inventory permit, CTV exposure may also be evaluated alongside website, app or business outcomes.

However, a served impression does not independently prove that a person was present, looked at the screen, remembered the advertisement or purchased because of it. Google notes that direct viewability measurement is not always possible on CTV and gaming-console inventory; some measurement may be inferred. Source: Google Ad Manager Help

This is why a high video-completion rate should not automatically be described as equivalent human attention.

Neither system should be treated as automatic proof of causality. Audience delivery, platform attribution and incremental business impact answer different questions.

The PCA TV Buying Clarity Map

Before approving a plan labelled “TV,” “OTT” or “CTV,” ask these four questions:

  1. Delivery route: Did the content reach the viewer through cable/DTH or through the internet?
  2. Viewing device: Was it watched on a television, mobile phone, desktop or tablet?
  3. Buying method: Was the advertising bought through a broadcaster/media-agency agreement or a digital/programmatic platform and publisher deal?
  4. Measurement source: Are the numbers coming from an independent audience currency, a publisher, the buying platform, the advertiser’s analytics or a controlled experiment?

If the proposal cannot answer all four, the media label is not yet precise enough for an informed investment decision.

A practical pre-buy checklist

The decision that still belongs to the marketer

CTV offers digital buying flexibility and more granular delivery signals than a conventional broadcast buy. That does not make every CTV impression better than Linear TV, nor does it make the platform dashboard an independent source of truth.

The marketer’s job is to match the media environment with the business objective, verify what is actually being purchased and separate delivery from attention, attribution and incremental impact.

How did the content reach the screen, how was the advertisement purchased, and what evidence will tell us whether the investment worked?

PCA Engine helps brands and marketing teams review media plans across Linear TV, OTT, CTV and digital buying. If a proposal mixes screens, inventory types or measurement claims without explaining the differences, discuss a TV and CTV Media Clarity Review with Meenaa. Initial priorities can be discussed first; a detailed audit and roadmap are scoped separately.
