A device and method for generation of digital advertisement displays in real time in digital TV-transmissions. In such digital TV-transmissions, a digital coding of the image material is made before the transmission is made; this coding compresses the content of the image as much as possible to minimize necessary bandwidth utilization at transmission of the signals. In connection with this coding and by means of pattern recognition, different patterns are identified for predefined objects in the image material, such as for example identifying an object with an unique coloring. Via the pattern identification, the image coder obtains information via a table of what the original object looks like. Also included in the table is information about which advertisement display is to be placed inside the identified object. Thus, starting from the identified object in the image material and the original form of the identified object, the advertisement display is introduced into an image storage in a TV-receiver, and the image material is transformed. TV-viewers in this way see a virtual advertisement message in the TV-transmission. |
