This year, the H.265 (or HEVC) standard is generating major buzz for its huge gains in compression efficiency, and may be poised to overtake its forefather H.264 - the foundation of most online video. You can’t fully enjoy it, however, unless your PC is prepared, so here’s how to get on board. But advanced video compression software, called codecs, can help reduce how much bandwidth video hogs.
