Some tracking domains used by Japanese TV stations

・d-log.asahi.co.jp ・d-log.bs-asahi.tv ・view.fujitv.co.jp ・recv-jnn.tbs.co.jp

These are the domains I found to be used to track your watching activities on an Android TV.

Some official statements about this tracking can be found here (both in Japanese): https://www.ytv.co.jp/privacy/experiments2022/index.html https://www.tv-asahi.co.jp/tvdata/

There is a blog post of an independent analysis by an experienced individual here (also in Japanese): https://qiita.com/kujira-desu/items/d98587c10fb44d668f8f

Reading through the official statements they tell you that your watching durations as well as your IP address, postal code, identifier, and software information bundled into a TV are sent to the TV station you tune in (which is confirmed by the aforementioned individual) and they may be shared with 3rd parties.

Also, the statements say more other TV stations are doing the same, meaning there are more domains used but I couldn’t find them due to regional limitations.

If you do not live in Japan it is impossible to reproduce this, so feel free to close this issue as invalid if you don’t feel like adding those domains without proving yourself.

Thank you.
