Talk:H.262/MPEG-2 Part 2

Merge H.262 and MPEG-2 Part 2

I suggest to merge this article into MPEG-2 Part 2 or vice versa. As it is stated in the H.262 article: the two documents are completely identical in all aspects (except perhaps the cover page and the price to buy a copy of the document).

(As I see, the H.262 article was created on Wikipedia in 2005 and the MPEG-2 Part 2 article in 2007.) --89.173.68.106 (talk) 08:53, 31 October 2009 (UTC)

Hi, eighty nine, one hundred seventy three, sixty eight, one hundred and six

This is no longer a matter of personal preferences. The is an article fork issue. Article forks are not allowed in Wikipedia. In case of forks, articles are either merged or deleted.

I'm proceeding with merger.

2013 Revision

I've updated the references and history section for the third edition of the standard (2013), but none of the technical content. I'm not familiar enough with the new edition yet to know what needs changing (e.g. new profiles), so revisions from the better-informed are welcome! Simon Brady (talk) 05:34, 24 July 2014 (UTC)

Interlace note

The article says:

but also provides support for interlaced video (an encoding technique used in analog NTSC, PAL and SECAM television systems).

Interlace is also used in digital TV, not just analog.

Improvements over MPEG-1 video

Conspicuous by its absence from the article, as far as I can tell, is the amount and cause of efficiency improvement over MPEG-1 video. --Damian Yerrick (talk) 23:50, 12 May 2016 (UTC)

If you're talking about compression, MPEG-2 basically doesn't have better compression than MPEG-1 (except when coding interlaced video, which MPEG-1 wasn't designed to handle). For progressive-scan video (coded with the Main profile, which is the only profile of MPEG-2 that the general public is familiar with), it is almost exactly the same design as MPEG-1. There are a couple of differences, but they seem very minor. Mulligatawny (talk) 00:29, 3 June 2017 (UTC)
