MPEG2HEVC
MPEG2HEVC is a term used to describe methods for encoding MPEG-2 video content with the High Efficiency Video Coding (HEVC, H.265) codec, or the corresponding transcoding systems that convert MPEG-2 to HEVC bitstreams. It is not an official MPEG standard; rather, it reflects industry and research interest in applying HEVC’s improved compression to legacy MPEG-2 material.
Technical approaches typically fall into two categories. Decode-then-encode transcoding decodes MPEG-2 video to raw pictures, then
Potential benefits include higher compression efficiency, enabling lower bitrates for comparable quality and easier delivery over
MPEG2HEVC is commonly discussed in archival, broadcast migration, and streaming pipelines as a practical approach to
