JPEG: Difference between revisions

{{Cquote|High-quality photographic images on web pages proved to be one of the killer applications for the success of JPEG. JPEG was included in web browsers from as early as February 1993. Thus, the boom in the web was parallel to the popularity of JPEG. In the second half of the 1990s, another killer application was digital photography, which got an additional killer application in the early 200s, namely digital photography by mobile and from 2007 smart phones.|||István Sebestyén (June 2020) "[https://www.itu.int/dms_pub/itu-s/opb/journal/S-JOURNAL-ICTS.V3I1-2020-13-PDF-E.pdf Some Little-Known Aspects of The History of the JPEG Still Picture Coding Standard (1986 - 1993)]" ITU Journal : ICT Discoveries Vol 3(1), 12 June 2020}}

The JPEG also had its own patent policy. The so-called baseline mode, which was common to all JPEG variants to enable interoperability among all JPEG coders, had to be royalty free . Meanwhile, optional feature RAND (reasonable and non-discriminatory) licensing was permitted. The arithmetic coder mentioned before was such a RAND component. It was only optional, so it could be left out from a given use and implementation. The IJG first implemented the arithmetic coder, but when they found out that it was a royalty-bearing component, they immediately removed it from the open source code.|||István Sebestyén (June 2020) "[https://www.itu.int/dms_pub/itu-s/opb/journal/S-JOURNAL-ICTS.V3I1-2020-13-PDF-E.pdf Some Little-Known Aspects of The History of the JPEG Still Picture Coding Standard (1986 - 1993)]" ITU Journal : ICT Discoveries Vol 3(1), 12 June 2020}}
