Abstract
A method and concomitant apparatus for incorporating one or more relatively low bitrate information streams (e.g., MPEG) into a relatively high bitrate information stream (e.g., SDTI) in a manner aligning low bitrate sub-stream splice entrance points and splice exit points within the frame boundaries of the high bitrate information stream. In this manner the splicing of the relatively high bitrate information stream at appropriate In Frames and Out Frames will provide relatively seamless splicing of information sub-streams.
