The HEVC extension is a proposed new video compression standard that would offer greater efficiency and flexibility over the current H.264 standard. While there is no agreed upon definition of what features the HEVC extension would include, it is generally thought to include enhancements to image and video quality, as well as increased compression efficiency. There is no definitive timeline for when the HEVC extension might be finalized, and thus far there has been little public discussion or development on the topic.
