ACR in video advertising stands for Automatic Content Recognition. ACR is a technology that can automatically analyze audio and visual components of video content to identify the specific program, movie, or advertisement being watched.
Manufacturers typically build ACR into smart TVs, streaming devices, and sometimes even set-top boxes. ACR technology gathers viewership data on what people watch. This data is collected without the user actively needing to input their preferences.
In 2020, The Trade Desk integrated Samba TV’s core data in Australia, generated by the company’s Automated Content Recognition (ACR) technology; a way to provide actionable insights into what consumers are actually watching across Broadcast Linear, Cable, and OTT video and the effectiveness of advertising campaigns. Samba TV data at the time was built from a global network of over 26 million Smart televisions.
OneView Ad Platform from Roku, launched in 2020, enables advertisers to plan and measure using linear TV data from ACR on North America’s #1 licensed TV OS.
Nielsen last year announced it has now access to ACR data footprint from LG.
How Does ACR Work?
- Content Fingerprinting: ACR creates a unique digital "fingerprint" for a piece of video content (show, movie, ad) by analyzing its audio and visual elements. These fingerprints are stored in a database.
- Monitoring Devices: ACR-enabled devices continuously monitor the video being played. They take small samples and generate fingerprints from them.
- Database Matching: The device compares these sampled fingerprints against the vast database of stored fingerprints. If there's a match, the ACR technology identifies the content.
Why ACR Matters for Video Advertising
- Detailed Viewership Insights: ACR eliminates the need for surveys or panels to determine what people are watching. It provides highly accurate data about viewing habits across linear TV and streaming platforms.
- Precision Targeting: Advertisers can target ads to viewers based on their specific content preferences (e.g., someone who watches a lot of cooking shows might see ads for kitchen appliances).
- Cross-Device Targeting: ACR enables advertisers to track viewers across different devices (e.g., TV, phone, tablet) and tailor ads accordingly.
- Ad Measurement: ACR allows advertisers to track how many people saw their ads, how frequently, and whether viewers engaged with them.
Example of ACR in Action
Imagine you're watching a football game on your smart TV. ACR technology recognizes the game and collects data about your viewership. An advertiser might use this data to serve you the following:
- Ads for other sporting events you might enjoy
- Targeted ads for team merchandise on your smartphone
- Ads for restaurants or sports bars that are running game-day specials
Concerns about data privacy
ACR data raises serious concerns about data privacy. Here's a breakdown of the key issues:
1. Extensive Tracking Without Clear Consent
- Hidden Collection: Most people are unaware that their viewing data is being collected in the first place. ACR technology is often enabled by default in smart TVs and streaming devices, and its implications may not be well-explained during setup.
- Fine-grained Data: ACR collects incredibly detailed data, including what you watch, when you watch it, for how long, and even if you change channels or fast-forward ads. This paints a very intimate picture of your interests and habits.
2. Data Sharing and Profiling
- Third-Party Access: ACR data is valuable to advertisers, data brokers, and other entities. Your viewing data could be shared with these third parties without your direct knowledge or control.
- Individual Profiling: Combining ACR data with other information (like your online browsing or purchase history) allows companies to build comprehensive profiles about you. These profiles can be used for targeting ads, influencing pricing, or even making assumptions about your interests, beliefs, or socioeconomic status.
3. Limited Opt-out Options
- Difficult to Disable: While most devices do offer the option to disable ACR, finding and understanding the settings can be a confusing process.
- Lack of Transparency: Companies benefiting from ACR data aren't always transparent about how the data is used, who it's shared with, and how long it's retained.
4. Potential for Misuse
- Sensitive Inferences: ACR data can reveal personal information, including political preferences, health conditions, religious beliefs, and more. This could be misused for discrimination or exploitation.
- Surveillance Concerns: In the wrong hands, ACR data could potentially be used by governments or other authorities for surveillance purposes.
What Can Users Do?
- Check The Settings: Thoroughly explore the privacy settings of your smart TV and streaming devices. Disable ACR functionality wherever possible.
- Support Privacy Legislation: Advocate for stronger legislation around data collection and consumer privacy.
- Be Mindful: Exercise caution about the devices you bring into your home and the information they collect.
