From Apple’s announcement: “In one word, efficiency. And primarily, encoding efficiency. HEVC is about 40% more efficient than AVC. It means that your user is going to see startup at a decent quality 40% faster, and when the player adapts its way all the way up they'll see content that looks 40% better. We are making HEVC widely available. On our newest devices we have support for HEVC built into the hardware. Even on older devices that don't have that hardware support, we are still going to deploy a software HEVC codec. So, HEVC is going to be a lot of different places.”

The answers to every company’s HEVC vs. AVC analysis can be summed up in two fundamental benefits the HEVC codec offers:

  • HEVC is roughly twice as efficient as AVC

  • HEVC enables 4K and High Dynamic Range

Using the HEVC codec, you get higher video quality at the same bandwidth as AVC, or you can deliver the same quality at half the bandwidth that you could using AVC.
