Abstract:
A method for mixing a first video signal and a second video signal, the method comprising at a mixing device receiving the first video signal; receiving the second video signal; receiving a transformation information signal dividing the first video signal into a transparent region and a non-transparent region and representing a spatial relationship between the first video signal and the second video signal; transforming the second video signal in accordance with the transformation information signal; and combining the non-transparent region of the first video signal with a portion of the transformed second video signal, the portion of the transformed second video signal being rendered in the transparent region of the first video signal.
