Abstract:

A method of splicing video content from a secondary encoded video stream into a primary encoded video stream, the method including the steps of identifying a splice out-time tand a splice in-time t, at least T time after t, in the primary stream; causing the fullness of primary encoder's virtual buffer to be less than XB, where X is greater than 0 and less than 1, at the first decode times after tand t; encoding the secondary stream such that an initial coded picture is transmitted in no more than B/(XR) time, and encoding the second stream such that, at a final coded picture's decode time, the fullness of the secondary encoder's virtual buffer is less than XB; and replacing video content of the primary stream from tthrough t+T, with the video data of the second stream.
