Consideration", and performed further experiments to evaluate various proposed features. The first working draft specification of HEVC was produced at the third JCT-VC meeting in October 2010. Many changes in the coding tools and configuration of HEVC were made in later JCT-VC meetings. On January 25, 2013, the ITU announced that HEVC had received first stage approval (consent) in the ITU-T Alternative Approval Process (AAP). On the same day, MPEG announced that HEVC had been promoted to Final Draft International Standard (FDIS) status in the MPEG standardization process. On April 13, 2013, HEVC/H.265 was approved as an ITU-T standard. The standard was formally published by the ITU-T on June 7, 2013, and by the ISO/IEC on November 25, 2013. On July 11, 2014, MPEG announced that the 2nd edition of HEVC will contain three recently completed extensions which are the multiview extensions (MV-HEVC), the range extensions (RExt), and the scalability extensions (SHVC). On October 29, 2014, HEVC/H.265 version 2 was approved as an ITU-T standard. It was then formally published on January 12, 2015. On April 29, 2015, HEVC/H.265 version 3 was approved as an ITU-T standard. On June 3, 2016, HEVC/H.265 version 4 was consented in the ITU-T and was not approved during a vote in October 2016. On December 22, 2016, HEVC/H.265 version 4 was approved as an ITU-T standard. Patent licensing On September 29, 2014, MPEG LA announced their HEVC license which covers the essential patents from 23 companies. The first 100,000 "devices" (which includes software implementations) are royalty free, and after that the fee is $0.20 per device up to an annual cap of $25 million. This is significantly more expensive than the fees on AVC, which were $0.10 per device, with the same 100,000 waiver, and an annual cap of $6.5 million. MPEG LA does not charge any fee on the content itself, something they had attempted when initially licensing AVC, but subsequently dropped when content producers refused to pay it. The license has been expanded to include the profiles in version 2 of the HEVC standard. When the MPEG LA terms were announced, commenters noted that a number of prominent patent holders were not part of the group. Among these were AT&T, Microsoft, Nokia, and Motorola. Speculation at the time was that these companies would form their own licensing pool to compete with or add to the MPEG LA pool. Such a group was
