ACR works something like Shazam for whatever's on screen. It periodically captures snapshots of the displayed content and matches them against a reference library to identify exactly what's playing, independent of any tracking built into the app itself (UC Davis, 2024; arXiv, 2024). Researchers call this second-party tracking, distinct from the trackers embedded inside individual streaming apps, because it doesn't care which app or input is feeding the screen.

Capture rate and transmission rate aren't the same thing. LG's own documentation describes grabbing frames every 10 milliseconds, but the audit only observed actual network transmissions roughly every 15 seconds, meaning captured frames get batched into a periodic fingerprint rather than sent the instant they're grabbed (arXiv, 2024).

On the Samsung and LG units tested, ACR traffic peaked during linear antenna TV and HDMI use, and dropped by as much as 12 times in other scenarios, including streaming through third-party apps (arXiv, 2024). Treat that as a finding about two manufacturers in two countries, not a rule that covers every brand or input. Regulators have been down this road before: the FTC sued Vizio and its analytics partner Inscape nearly a decade ago over ACR tracking conducted without user consent (arXiv, 2024).

The business case goes past "better recommendations." Researchers describe ACR as the main input platforms use to build viewing-habit profiles, noting a TV maker can infer that a household watches football on Sunday afternoons and news in the evening, then sell targeted advertising against that pattern (UC Davis, 2024). A July 2026 Pocket-lint report puts it more bluntly: manufacturers frame ACR as personalization, but the real purpose is letting advertisers refine targeting based on what's actually showing on the screen.

One more thing worth knowing before diving into menus: "Google TV" is an operating system, not a single ACR system. Sony runs its own Samba-branded tracking on top of it, and other manufacturers label their versions differently, which is why the same underlying function shows up under different names depending on the set. ACR isn't switched on for every Google TV model, either, and it's absent entirely from the standalone Google TV Streamer (Pocket-lint).

Samsung calls its ACR feature Viewing Information Services. Grab the remote and follow these steps, as reported in a June 2026 Pocket-lint investigation:

1. Press Home on the Samsung remote.
2. Go to Settings, then All Settings.
3. Open General & Privacy.
4. Select Privacy Choices (on older sets, this may be labeled Terms & Privacy instead).
5. Find Viewing Information Services, turn it off, and confirm with OK.

Pocket-lint notes this exact path can shift by model year, flagging the older "Terms & Privacy" label as one example (Pocket-lint). If a label doesn't match exactly on your set, look for anything referencing viewing data or privacy choices nearby.

Whether ACR starts on or off is genuinely inconsistent depending on where you look. UC Davis researchers studying smart TV setup flows broadly found that users are typically prompted to opt in to ACR-style tracking during initial setup (UC Davis, 2024), a general finding that doesn't establish Samsung's specific default. Pocket-lint's Samsung-focused reporting instead found Viewing Information Services commonly enabled by default on many Samsung units (Pocket-lint). Both can be true depending on region, model, and how a given setup flow presents the consent screen. Check the toggle yourself rather than assuming your set matches either description.

Turning it off stops the TV from sharing viewing data with Samsung, and streaming apps and core features keep working exactly as before (Pocket-lint). Samsung's privacy policy, which took effect last year, separately documents cross-device data collection through cookies and third-party analytics tools, including Google Analytics, Firebase Analytics, and Adobe Analytics (Samsung Privacy Policy). That policy simply establishes those as existing categories of collection across Samsung's devices and services generally; it doesn't say whether any of them are tied to the Viewing Information Services toggle specifically, so treat the two as documented separately rather than assuming one switch governs both.

There's real evidence this particular opt-out works as advertised. The black-box audit found a complete absence of communication with previously identified ACR domains once the Samsung and LG test units had opted out, confirmation that the mechanism functions as intended, at least on the two manufacturers and two countries covered by that study (arXiv, 2024).

The steps for these three brands all come from a single July 2026 Pocket-lint report, not from the kind of network-level testing behind the Samsung and LG findings above. Treat them as a strong, specific lead rather than a lab-verified result.

Sony

1. Open Settings from the home screen.
2. Select Initial Setup.
3. Choose Samba Interactive TV, then Disable.
4. Go back to Settings, then Apps.
5. If Samba Services Manager appears in the list, select it. If it doesn't, the process is already finished.
6. Tap Clear Cache, then Force Stop.
7. Select Disable.

Samba Interactive TV is a Samba TV service layered on top of Sony's Google TV software, a concrete example of a manufacturer building its own tracking system on a shared operating system. Pocket-lint doesn't note any loss of core streaming function from disabling Samba, though it doesn't confirm what happens to Sony's other recommendation features either. Treat anything past "the tracking service turns off" as unverified.

Hisense

1. Open Settings, then go to System, then Privacy.
2. Look for an option called Smart TV Experience or Viewing Information Services.
3. Read the description. If it matches what ACR does, turn it off.

TCL

1. Open Settings, then System, then Display & Sound.
2. Under Intelligent Settings, turn everything off.

That second step is the instruction as reported. As a precaution, it's worth reading each entry under Intelligent Settings before flipping it, since Pocket-lint's own reporting cautions that menu labels vary even within a single brand (Pocket-lint). No one has independently confirmed which specific control in that menu maps to ACR, so switching off only some entries instead of the whole block isn't a verified way to disable it, just a more cautious way to poke around before committing.

The supplied Samsung and LG audit is the network-level test cited in this guide; nothing else here has been checked the same way (arXiv, 2024). Everything in this section is a reported term to search for on your own set, not a verified kill switch.

On any TV not covered directly above, dig through Settings, then Privacy, General, or System, looking for language like "viewing information," "content recognition," "interactive TV," or "personalized recommendations" and "personalized advertising." Those are the labels Pocket-lint reports finding across the specific brands covered above, not a naming convention confirmed to hold across every manufacturer (Pocket-lint).

Don't assume a similarly named toggle is automatically ACR. LG, for example, has a separate feature called Always Ready, with its own dedicated support guide describing how to disable it. That's a real, distinct function, not established here as an ACR control (LG Support). Vizio, Roku TV, Fire TV, Philips, and any unlisted model deserve the same caution. Identify the exact model and firmware version, then check that manufacturer's current support documentation before treating any switch as ACR's equivalent.

Turning off ACR doesn't clear the whole board. Pocket-lint is direct about this: disabling ACR doesn't eliminate all tracking on a smart TV (Pocket-lint), and Samsung's privacy policy documents cross-device data collection and third-party analytics that the Viewing Information Services toggle never claimed to touch (Samsung Privacy Policy).

As a general checklist, work through ad-personalization settings, voice-assistant permissions, and the privacy controls buried inside individual streaming apps after switching off ACR. These tend to operate independently of the ACR toggle, though how each brand implements them varies enough that no single menu switch is likely to cover all of them.

Only one control in this guide has been confirmed at the network level to stop ACR traffic: Samsung's Viewing Information Services toggle, tested alongside LG's equivalent on units in the US and UK (arXiv, 2024). The Sony, Hisense, and TCL steps address the same kind of tracking by description, reported by Pocket-lint, but nobody has run the network test to confirm they behave the same way once switched off.

That gap matters less than it might sound. A reported, unverified toggle is still worth flipping, since trying costs nothing and the upside, if it works as described, is real. Just don't mistake finding the menu label for confirming the traffic stopped, and don't mistake turning off ACR for turning off tracking generally. The rest of that picture, cookies, cross-device analytics, ad personalization, lives in separate settings this one switch was never built to touch.
