Kind Code:
A
Abstract:
The invention relates to a circuit (2) for generating a composite output picture signal (6) such as a picture signal comprising a PIP (Picture-in-Picture) signal or a DW (Double window) signal on the basis of at least two input picture signals (4.1, 4.2), the circuit comprising a color decoding unit (8) for decoding the at least two input picture signals (4.1, 4.2), and a composing unit (10) for generating the composite output picture signal (6) on the basis of the decoded at least two input picture signals. According to the invention, the color decoding unit (8) comprise a combining unit (14) for combining the at least two input picture signals (4.1, 4.2) into one combined picture signal (16), and one color decoder (18) for decoding the combined picture signal (16) to obtain a single decoded picture signal (12), the composing unit (10) being arranged to generate the composite output picture signal (6) on the basis of the single decoded combined picture signal (12). The invention also relates to a television apparatus provided with a circuit (2) according to the invention, and a display device (D) for displaying the output composite picture signal (6). Furthermore, the invention relates to a video tape recorder provided with a circuit according to the invention.
