A method and apparatus for providing a smooth transition of the transmission over a network between a first FGS encoded video stream and a second FGS encoded video stream wherein each of the FGS encoded video streams contains a base layer. The method comprises selecting a transmitted P-frame of the first video stream, selecting a next P-frame to be transmitted in the second video stream, determining a difference between the transmitted P-frame of the first video stream and the next to be transmitted P-frame of the second video-stream, and transmitting the difference between said P-frames over said network in place of said next to be transmitted P-frame. |
