Abstract

A video display device comprising a display to display a primary image, originating from a first input signal, and a picture-in-picture (PIP) overlaying the primary image and originating from a second input signal. The display characteristics of the PIP are changed in response to information, preferably a file extension, relating to the type of the first input signal in order to obscure as little as possible of the important parts of the primary image. In case the primary image contains much visual information the PIP is chosen small, positioned in the periphery of the display and/or transparent. In case the primary image contains little visual information the PIP is chosen large, centered and/or non-transparent. Useful for Integrated Digital TV cum Broadband TV (IDTV-BBTV) devices, where the primary image is a broadband image and the PIP is a TV image.

Claims

1. A video display device (1) comprising:

a display (4) adapted to display a primary image (5) and a picture-in-picture (PIP) (6) overlaying the primary image (5),

first input means (3) adapted to receive a first input signal, said first input signal defining said primary image (5), and said first input signal comprising information relating to the type of said first input signal,

second input means (2) adapted to receive a second input signal, said second input signal defining said PIP (6),

a processor operatively coupled to the display (4) and to the first (3) and second (2) input means, said processor being adapted to analyze the information relating to the type of the first input signal and to change a PIP display characteristic in response to said information.

2. A video display device (1) according to claim 1, wherein the first input signal comprises at least one file, and wherein the information comprises information relating to a file extension of the first signal.

3. A video display device (1) according to claim 1, wherein the PIP display characteristic is at least one of a position of the PIP (6) on the display (4), a display size of the PIP (6), and a transparency of the PIP (6).

4. A video display device (1) according to claim 1, wherein the first and/or the second input signal is a broadband signal.

5. A video display device (1) according to claim 1, wherein the first and/or the second input signal is a TV signal.

6. A video display device (1) according to claim 1, wherein the first and/or the second input signal is an Audio-Video (AV) signal.

7. A video display device (1) according to claim 1, wherein the video display device (1) is an Integrated Digital TV device.

9. A computer program being adapted to perform the method steps of claim 7 when running on a general purpose computer.

8. A method of controlling a picture-in-picture (PIP) display characteristic in a video display device (1) comprising a display (4) and a processor being operatively coupled to the display (4), the method comprising the steps of:

receiving a first input signal, said first input signal defining a primary image (5) to be displayed on the display (4), and said first input signal comprising information relating to the type of said first input signal,

receiving a second input signal, said second input signal defining said PIP (6), analyzing, by means of said processor, the information relating to the type of the first input signal, and

changing a PIP display characteristic in response to said information.
