METHOD AND APPARATUS FOR ALIGNING SUB-STREAM SPLICE POINTS IN AN INFORMATION STREAM

摘要

A method and concomitant apparatus for incorporating one or more relatively low bitrate information streams (e.g., MPEG, SS1 and SS2) into a relatively high bitrate information stream (e.g., SDTI, 320) in a manner aligning low bit 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 (321 and 322) will provide relatively seamless splicing of information sub-stream.
