Abstract:
A method for splicing a first compressed digital video bit stream and a second compressed digital video bit stream comprising the steps of:providing a first compressed digital video bit stream, said first compressed digital video bit stream containing a plurality of entry points, each of said entry points having an associated threshold video buffer verifier fullness, such that if an actual video buffer verifier fullness, just before removal of the bits of a first picture following the entry point equals or exceeds the associated threshold fullness, the portion of the first compressed digital bit stream following the entry point may be decoded without causing said video buffer verifier to underflow, using an encoder, generating a second compressed digital video bit stream, said second compressed digital video bit stream resulting in an ending fullness of a video buffer verifier one picture time after removal of the bits corresponding to a last picture of the second compressed digital video bit stream, said ending fullness equaling or exceeding the threshold fullness associated with one of said entry points, and splicing said first and second compressed digital video bit streams so that said last picture of said second compressed digital bit stream is immediately followed by said one of said entry points in said first compressed digital video bit stream.
