Abstract: Invention relating to a device and method which allows generation of digital advertisement displays in real time at digital TV-transmissions. The invention is characterized in that it is applicable for digital TV-transmission. At such transmission a digital coding of the image material is made before the transmission is made; the main purpose of this coding is to compress the content of the image as much as possible to minimize necessary bandwidth utilization at transmission of the signals. The invention is based on that one in connection with this coding by means of recognition of pattern identifies different in advance defined objects in the image, such as for instance a display with one in the connection unique colouring. Via one in the device arranged table, the image coder can, on the basis of identified colouring, obtain information of what the original object looks like, for instance an advertisement display. In said table there also is defined the advertisement display which shall be placed in for that purpose intended space. Starting out from the identified object in the image storage and the original form, the advertisement display can be transformed and introduced into the image storage. The TV-viewers in this way will see a virtual advertisement message in the TV-transmission.

Abstract: Method and means for a regulator for the servo control of a marine craft, for instance a torpedo, with variable speed and angle of attack. A first sensor (1) monitors the angle of attack, whilst a second sensor (8) monitors the depth of the craft. A revolution counter (3) and a filter (4) create an acceleration-compensating signal which is substracted from an angle-of-attack signal emitted by the first sensor (1), whereupon the signal is transmitted to a rudder servo system.
