Abstract (en)
[origin: WO0057295A1] Hot spot data is encoded in portions such as the display data portion of a television signal such that the encoded hot spot data is unaffected by any alteration to television signals performed by intermediate broadcasters. Hot spot data may include data identifying the location of hot spots in an image frame and vendor system data associated with the hot spots. A transaction enabler block (330) may display images represented by the image frames and enable a viewer to access vendor systems by selecting the hot spot areas via a remote control (320).
