<p> A method and apparatus for providing a smooth transition of the transmission over a network between a first FGS encoded video stream (305) and a second FGS encoded video stream (310) wherein each of the FGS encoded video streams contains a base layer (325, 330). The method comprises selecting a transmitted P-frame (315) of the first video stream, selecting a next P-frame (320) to be transmitted in the second video stream, determining a difference (235) between the transmitted P-frame (315) of the first video stream and the next to be transmitted P-frame (320) of the second video-stream, and transmitting the difference (235) between said P-frames over said network in place of said next to be transmitted P-frame (320).</p> |
