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. |
