Does this mean it can identify the content being delivered over HDMI ? Not sure if the live TV example here is through their own internal tuner or using a cable

  I believe the tech being used very literally scans the stuff being shown on screen. I have read about this tech in the past. It also raises privacy concerns, as if you watch old family movies or some such, the TV could be beaming metadata of that back to the mothership for analysis. Creepy times we live in.

    Wow. I'm curious to know how Inscape (the scanning tech mentioned here) is able to circumvent HDCP in this case. Do they have special access ?

      The TV is the one displaying, it obviously needs to decrypt the content.

      Smart TV SoCs usually have a capture engine that taps into the video stream being sent to the screen after HDCP decryption and allows it to be DMA'd directly to main RAM [1], and from there analyzed and sent to the manufacturer's ad partner of choice. As long as the firmware does not allow the end user to access these decrypted frames in any way, the TV will still pass HDCP certification with no issues.
