H H.265简况（2009/06） 1. 现状 H.265是ITU-T VCEG规划的下一代编码标准。原本的计划是2005- 2008开始确定H.265的需求定义及具体算法的设计，2008- 2010期间正式推出，但从目前情况来看仍处于探索阶段：目标尚未明确，方向和方案仍 在集思广益之中，标准推出会延迟到2012年左右。 ITU目前官方说法是， ”The work on H.265 is currently in a conceptual/exploration phase. The fundamental issue is the technical challenge of achieving a substantial improvement relative to H.264. It is also possible that we could standardize further extensions/variations of H.264, which may impact the potential for an H.265. We may expect to potentially complete H.265 around 2012. However, the fundamental issue is that we must have a technical design that would merit the creation of such a standard. So it could hypothetically happen either sooner or later than that, depending on when suitable technology becomes available and sufficiently ……
