iso 13818-1 standard link broken.[edit]

Link to http://web.archive.org/web/20100611214610/http://neuron2.net/library/mpeg2/iso13818-1.pdf standard is broken. I wasn't able to find a free copy of it to replace it. Delete? 81.94.56.25 (talk) 11:09, 8 February 2009 (UTC)[reply]

. The link seems to be back online again 78.53.43.73 (talk) 09:32, 7 March 2009 (UTC)[reply]

The link results in a 403 HTTP status (Forbidden) right now. Anyway, I guess this is a link to the MPEG-2 Systems specifications, which are not freely available, so no mater whether the link works or not, it should be removed. Teyut (talk) 19:03, 24 October 2014 (UTC)[reply]

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

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. Teyut (talk) 19:06, 24 October 2014 (UTC)[reply]

broken link for SMPTE MPEG-RA[edit]

The citation 12 has a broken link http://smpte-ra.org/mpegreg/mpeg.html for SMPTE as the registration authority for MPEG stream identifiers. I believe the correct link is: https://smpte-ra.org/mpeg-ts-ids Chris Dolan (talk) 17:09, 13 September 2016 (UTC)[reply]

Done Your proposed link matches the archived version. I have made the correction. ~Kvng (talk) 16:29, 16 September 2016 (UTC)[reply]

AC-3 Audio[edit]

Why is AC-3 audio considered "non-standard data" when MPEG-PS is used for DVD-Video which has AC-3 as a standard? — Preceding unsigned comment added by Juventas (talk • contribs) 05:45, 23 December 2017 (UTC)[reply]
