Forward compatibility between System Stream (MPEG-1) and Program Stream (MPEG-2)

The article states that MPEG-2 Program Stream is forward compatible with ISO/IEC 11172 Systems layer (MPEG-1). However, the pack header format from MPEG-2 is different than the one in MPEG-1, so MPEG-1 de-multiplexers cannot decode it. Where is the forward compatibility then? MPEG-2 PS is backward compatible with MPEG-1 SS though. — Preceding unsigned comment added by Teyut (talk • contribs) 18:57, 24 October 2014 (UTC)[reply]
