BARC streaming measurement: how India measures OTT and CTV viewing

BARC's approach to streaming measurement

BARC India's streaming measurement is built on the same panel infrastructure as its linear TV measurement — the same households, the same BAR-O-Meters. The BAR-O-Meter on a smart TV can detect what is being shown on the screen, regardless of whether it is a linear TV channel, a streaming app, or content played from a USB drive.

For streaming apps, BARC's detection works through a combination of methods depending on platform cooperation:

• Watermarked streaming content: Streaming platforms that have agreed to embed BARC audio watermarks in their content can be detected passively by the BAR-O-Meter, the same way linear TV channels are detected. The meter hears the watermark, identifies the platform and content, and logs the viewing.
• ACR-based detection: For platforms that do not watermark their content, BARC has ACR (Automatic Content Recognition) capabilities that can identify content from its audio fingerprint rather than a specific watermark.
• SDK integration: Some platforms have integrated BARC's measurement SDK directly, enabling measurement through app-reported data rather than passive panel detection.

BARC Streaming — what it measures

BARC India's streaming measurement product covers OTT viewing that occurs on TV screens (smart TVs, streaming sticks, set-top boxes) within its panel households. This is specifically CTV viewing — not mobile or desktop streaming.

Platforms that participate in BARC's streaming measurement programme (which has grown over time) can have their TV-screen viewing measured through the BARC panel. BARC publishes streaming measurement data — weekly platform rankings, content rankings — that gives a panel-based view of relative platform popularity and viewership.

Key characteristics of what BARC streaming measures:

• TV-screen streaming only — mobile and desktop streaming are not in scope
• Panel-based — extrapolated from panel households to the Indian population, like linear TV data
• Relative rankings reliable — which platform had more viewers this week than last week is measurable with reasonable confidence
• Absolute audience figures less reliable — extrapolating from a panel to total India CTV viewers introduces significant confidence intervals

Platforms in BARC streaming measurement

Not all India streaming platforms participate in BARC's streaming measurement. Platform participation is voluntary (it requires embedding watermarks or cooperating with BARC's measurement methodology). As of 2024–25:

• Hotstar: Has participated in BARC streaming measurement. Star India's relationship with BARC (as a major broadcaster funding the measurement) means Hotstar streaming data is relatively well covered.
• SonyLIV, Zee5: Participate in BARC streaming measurement as extensions of their broadcast network relationships.
• JioCinema: Reliance / Viacom18 participation in BARC streaming has been less consistent. JioCinema prefers to report its own numbers — particularly for IPL, where JioCinema's claimed viewership figures (35M+ concurrent streams) are not verified through BARC's panel.
• YouTube, Netflix, Prime Video: Global platforms have limited or no formal BARC streaming measurement participation. YouTube and Netflix report their own India viewership data but this is self-certified and not panel-verified.

The pattern: Indian broadcast-affiliated platforms (Hotstar, SonyLIV, Zee5) tend to participate more; global platforms (YouTube, Netflix) and Reliance-backed platforms (JioCinema) tend to report their own numbers instead.

What BARC streaming measurement is NOT

• Not total India streaming audience: BARC streaming covers participating platforms on TV screens in panel households. It does not cover non-participating platforms, mobile viewing, or desktop viewing. Total India streaming audience is larger than what BARC's streaming measurement captures.
• Not ad impression measurement: BARC measures audience viewing, not ad delivery. It does not verify how many ad impressions were delivered, whether they were viewable, or whether brand safety standards were met. That requires separate ad verification tools (IAS, DoubleVerify).
• Not real-time: Like linear TV data, BARC streaming data is reported with a lag — typically weekly. It cannot be used for mid-campaign optimisation.
• Not cross-device: A viewer who watched Hotstar on their phone in the morning and on their smart TV in the evening appears as two separate events in different measurement systems. BARC sees only the TV-screen evening viewing.

How advertisers use BARC streaming data

Given its limitations, BARC streaming data is used directionally by India CTV planners rather than as a definitive planning currency:

• Platform ranking: BARC streaming data provides a panel-based ranking of which platforms are most watched on TV screens. This is useful for confirming the relative scale of Hotstar vs SonyLIV vs Zee5 in a planning brief.
• Content performance: For participating platforms, content-level data (which shows or films drove viewership) helps planners identify contextual environments for advertising.
• Trend tracking: Week-on-week and quarter-on-quarter BARC streaming trends inform how the CTV market is evolving — which platforms are growing, which are declining.
• What it cannot do: Provide a reliable total India CTV reach figure, verify individual campaign delivery, or cover non-participating platforms like JioCinema or YouTube.
