Abstract: The present invention relates to a system and method of inserting a secondary stream of digital frames into a primary stream of digital frames without transcoding any of the streams, where the primary stream is encoded according to a first format and the secondary stream is encoded according to a second format where each frame is independent of a succeeding frame. The approach comprises receiving a requested splice-out point in the primary stream; determining an optimal splice-out point in the primary stream in dependence upon the requested splice-out point; receiving a requested splice-in point in the primary stream; determining an optimal splice-in point in the primary stream in dependence upon the requested splice-out point; and replacing the section of the primary stream between the optimal splice-out point and the optimal splice-in point with the secondary stream.

Abstract: The present invention relates to a system and method of inserting a second stream of digital frames into a primary stream of digital frames, where the primary stream is encoded according to a first format. The approach comprises determining a reference point in the primary stream; determining a section of the primary stream adjacent the reference point; creating a corresponding recoded version of the adjacent section of primary stream, such that the recoded version is in a second format where each frame in the recoded version is independent of a succeeding frame; replacing the section of the primary stream with the corresponding recoded version, and inserting the second stream adjacent the replaced section.
