HEVC – Definition and Pronunciation
What is HEVC?
High Efficiency Video Coding (HEVC) is a newly-developed standard (first stage approval in January 2013) for video compression developed by the ITU-T and ISO; it is a joint publication of ISO/IEC and ITU-T, formally known as ISO/IEC 23008–2 (ISO-MPEG H Part 2) and ITU-T Recommendation H.265. H.265 is seen as a successor to H.264/MPEG-4 AVC. HEVC has the same general structure as MPEG-2 and H.264/AVC, but it affords more efficient compression; namely, it can provide the same picture quality as the predecessor (H.264) but with a lower datarate (and storage requirement), or it can provide better picture quality than its predecessor but at the same datarate (and storage requirement).
Examples of HEVC
Since HEVC provides superior video quality and up to twice the data compression as the previous standard (H.264/MPEG-4 AVC), the implications for satellite operators are that users (e. g., the Dish Network, DirectTV) may, in principle, require less transponder bandwidth to support the necessary video quality.

HEVC is a newly developed standard. It has the same general structure as MPEG-2 and H.264/AVC, but it affords more efficient compression; namely, it can provide the same picture quality as the predecessor but with a (much) lower data rate (and storage requirement), or it can provide better picture quality than its predecessor but at the same data rate (and storage requirement).
From “DVB-S2 Modulation Extensions and Other Advances”.
The newly emerging H.265/HEVC (High Efficiency Video Coding) video compression standard (algorithm) provides up to 2x better compression efficiency compared with that of the baseline H.264/AVC (Advanced Video Coding) algorithm; however, it also has increased computational complexity requiring more advanced chip sets.
