<p>The invention relates to a TV-receiver 220 for receiving and decoding a broadcasted TV-signal representing an image and control data wherein the control data defines a vector indicating a location of a partition of important subject matter within said image. The invention further relates to an image display apparatus 200 and to a TV-system comprising the TV-receiver and to a method for operating the TV-receiver. It is the object of the present invention to improve a known TV-receiver 220, an image display apparatus, a TV-system and a method for displaying an image such that at least a partition of important subject matter within the original broadcasted image can entirely be shown on a screen even if the size of said screen is smaller than the size of said partition with only a minimal loss of details. This object is solved in that the control data further defines the size of said partition showing said important subject matter and that the TV-receiver 220 further comprises a re-sampling unit being adapted to extract a re-sampled image to be displayed on the screen of a display device 200 from said decoded image by re-sampling said decoded image at a variable re-sampling rate defined at the receiving end such that the size of the partition of important subject matter in the re-sampled image is adapted according to a criterion.</p> |
