How does NHK do this?
 

According to this NHK press release they can now send a QR Code to a TV on an individual basis.

How do they know where a TV is located? Is there some new technology?

sorry in poor English

The detailed information was not found...
The personal information such as zip codes set to a receiver
Not a picture, send data to a receiver and display QR cord

siokan thank you but I do not understand?

It says NHK has developed a system where it can have TV-set owners to register their postal codes and other info (which the article doesn't specifically mention) within the TVs. This enables NHK to send area-specific and/or other-factors-specific QR Codes onto the screens that the viewers in turn can take into their cellphones to look at the needed local infomation.

This is about emergency info, open hospitals on holidays and such.

This technique seems to be shown by an event held on March 9 from March 7.

No charge for admission.

フォロー有難う御座いますm(_ _)m
日本に居ないのか･･･

データ放送用のBMLにQRコードデータ乗せて
受信機のBMLブラウザで表示って事です

BMLはXhtml+JavaScriptをsubset化したものだったかな
ARIBのサイトに規格書転がってる筈です

Well that is interesting.

Thank you so much!
