METHOD FOR MODIFYING THE CONTENT OF A TELEVISION IMAGE
First Claim
1. A method for modifying the content of a target area (11) in a television image (7), the method comprising generating an original image signal (PGM1) by means of a camera (1), processing the original image signal by adding graphics (9) into the television image, determining the target area in the television image, transmitting further the processed image signal (PGM2) and the target area determining data, and inserting, at a later stage (14) of the signal transmission chain, substitutive content (15a, 15b) to the target area according to the target area determining data, characterized in that:
- the graphics (9) is added into the television image (7) according to a predetermined graphics percentage of coverage;
thatthe method further comprisesdetermining the shared area (13) of the target area (11) and the additional graphics (9) area in the television image, andtransmitting further, together with the processed image signal (PGM2) and the target area determining data, the shared area determining data and data proportional to the graphics percentage of coverage; and
thatto the shared area (13), the substitutive content (15a, 15b) is inserted according to the residual percentage of coverage not covered by the added graphics.

Abstract
The method for modifying the content of a target area in a television image comprises generating an original image signal (PGM1) by means of a camera, processing the original image signal by adding graphics into the television image, determining the target area in the television image, transmitting further the processed image signal (PGM2) and the target area determining data, and inserting, at a later stage of the signal transmission chain, substitutive content to the target area according to the target area determining data. According to the present invention, the graphics is added into the television image according to a predetermined graphics percentage of coverage; and to the shared area of the target area and the additional graphics area, the substitutive content is inserted according to the residual percentage of coverage not covered by the added graphics.
