HEVC, also known as H.265, is a video compression codec. It was developed to double the compression efficiency of the previous standard, H.264/AVC, hence the name High-Efficiency Video Coding.

This new compression standard has allowed broadcasters, pay-tv operators, and video streaming services, (and anyone else with an HEVC video encoder) to stream higher quality video at manageable bitrates, including in 4K resolution, whereas H.264 really struggles with anything higher than SD.

Now Germany has adopted DVB-T2 H.265, which means all the DVB-T2 should support HEVCE H.265 in Germany.
