H.265 a.k.a. HEVC: Videocodec of the future

Taking a look at H.264's successor



The H.265 standard, also known as the HEVC video codec, was finalized in April of 2013. H.265 is to become the technology that makes the breakthrough of video at 4K resolution possible. So, how does H.265 work exactly, and when can we expect support from various kinds of devices? We had a look.

Halfway through last year, we published a background article on video at 4K resolution (3840x2160); 4 times as high as the Full HD resolution, which now is commonly used for both televisions and most PC monitors. In that article, the term H.265 was briefly mentioned. This new video coding standard, which is also known as HEVC or High Efficiency Video Codec, is to be the driving force behind the 4K revolution. At the same time, it is to lower the required bandwidth for video material with lower resolutions. Products supporting HEVC have started to appear.

Samsung was already showing it off during its introduction of the Galaxy S4, the company behind DivX is also experimenting with 4K, and because of this we encounter the technology more and more. Plenty of reasons to take a closer look at this new video coding.
