Method and device for generating a video effect

1. A method for generating a video effect using a video signal processing device, comprising the following steps:

a) generating a horizontal and a vertical gating base signal,

b) combining the horizontal gating base signal with a first modulation signal,

c) combining the vertical gating base signal with a second modulation signal,

d) generating an amplitude distribution from the modulated horizontal and vertical gating base signals, and

e) generating a control signal from the amplitude distribution for controlling a mixing stage,

f) deriving a third modulation signal from a sound signal, and

g) modulating the control signal with the third modulation signal.

2. The method as claimed in claim 1 , further comprising;

separating the sound signal from a reception signal comprising both a video signal and the sound signal.

3. The method as claimed in claim 1 , further comprising;

generating a composite modulation signal from the first and/or the second and/or the third modulation signal.

4. The method as claimed in claim 1 , further comprising;

modulating a background color signal with the third modulation signal.

5. The method as claimed in claim 1 , further comprising;

modulating a background color signal with the control signal.

6. A device for generating a video effect having a generator for generating a horizontal and a vertical gating base signal, comprising;

means for modulating the gating base signals with a first and respectively a second modulation signal,

means for generating a control signal from the modulated gating base signals,

a mixing effect stage controlled by the control signal,

wherein

a sound signal processing stage is provided, which derives a third modulation signal from a sound signal and feeds it to the modulation means in order to modulate the gating base signal with the third modulation signal.

7. The device as claimed in claim 6 , wherein the device has a background color generator for generating a background color signal, to which is fed the third modulation signal and/or the control signal for the modulation of the background color signal.

8. The device as claimed in claim 6 , wherein the device comprises a plurality of cascaded mixing effect stages.

9. The device as claimed in claim 6 , wherein a sound signal separation stage is provided, which separates the sound signal from an overall signal comprising the sound signal and a video signal.

10. The device as claimed in claim 6 , wherein a filter bank is provided, which comprises various selectable filter types for processing the sound signal.
