Abstract
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.
Claims19
A method for smoothly transitioning between a first FGS encoded video stream and a second FGS encoded video stream wherein each of said FGS encoded video streams contains a base layer, said method comprising the steps of:
- selecting a P-frame of said first video stream transmitted over a network;
- selecting a next P-frame to be transmitted over said network in said second video stream;
- determining a difference between said transmitted P-frame of said first video stream and said next P-frame to be transmitted of said second video-stream;
- and
- transmitting said difference between said P-frames instead of said next P-frame to be transmitted over said network.
An apparatus for smoothly transitioning between a first FGS encoded video stream and a second FGS encoded video stream wherein each of said FGS encoded video streams contains a base layer, said apparatus comprising:
- means for selecting a P-frame of said first video stream transmitted over a network;
- means for selecting a next P-frame to be transmitted over said network in said second video stream;
- means for determining a difference between said transmitted P-frame of said first video stream and said next P-frame to be transmitted of said second video-stream;
- and
- means for transmitting said difference between said P-frames instead of said next P-frame to be transmitted over said network.
An S-Frame of an FGS encoded video stream comprising:
- a difference between a transmitted P-frame of a first video stream and a next P-frame to be transmitted of a second video-stream.
