A formal joint Call for Proposals on movie compression technologies was issued in January 2010 by VCEG and MPEG, and proposals have been evaluated at the first assembly of the MPEG & VCEG Joint Collaborative Team on Video Coding (JCT-VC), which took place in April 2010. A total of 27 entire proposals were being submitted. The initial operating draft specification of HEVC was developed at the third JCT-VC meeting in October 2010.
