In January 1993 I took the initiative to invite to the Rome meeting Mike Smith, head of the Information Technology Task Force (ITTF), the group inside the ISO Central Secretariat in Geneva looking after JTC1 matters. Mike provided advice on how this difficult issue could be treated without trespassing the limits set by the ISO/IEC directives. In the event, an MPEG-2 Patent Pool was established, managed by MPEG LA. This organisation acts as a "one-stop shop" for MPEG-2 Video and Systems patents (Audio is not part of the licensing), but there are a few companies licensing their technology separately.
– Title-by-Title - 12 minutes or less = no royalty; >12 minutes in length =
lower of (a) 2% or (b) $0.02 per title.

First Effort to deal with patent issue for MPEG-2

Leonardo Chiariglione《Patents and standards》
– /ride/patents_and_standards.htm If Gutenberg had lived in a culturally more advanced city like Venice or Florence, which had already started issuing litterae patentes ("open letters", whence the word "patent" comes from) since a few decades, he could have protected his invention with a patent. Some time later, MPEG had to deal with MPEG-2 patents. Many companies had participated in the MPEG-1 development not so much because they necessarily had plans to make products in that space, but because they were keen to be around and help tune up the MPEG machine for the big MPEG-2 deal.
• ISO/IEC recommended MPEG series standards
– MPEG-1, MPEG-2, MPEG-4
• ITU-T recommended H.26X series standards
– H.261, H.262, H.263, H.263+, H.263++ 1G standards 2G standards
– Europe DVB at 1997 – USA ATSC at 1997 – Japan ISDB at 1998 – China DTMB at 2006
AVS – one of the 2nd Generation
• In Feb2006, AVS video issued as Chinese national standard
• is the reason makes DTV possible at 1994 • and always a core concern for Digital TV system and any other digital video applications
