George Bradford on 18 Sep 15"One of the biggest issues concerning UHD/4K is how it will be encoded/compressed and what bit rate will be required to convey a high-quality image. As I've written before, everyone at NAB 2014 seems to have settled on H.265 (aka HEVC or High-Efficiency Video Coding) as the codec of choice for UHD/4K. HEVC is said to offer up to 50 percent greater efficiency than H.264 (aka AVC or Advanced Video Coding), which is often used for high-def content, and even greater gains in efficiency over MPEG-2. So I was particularly interested in a presentation called "Bit Rate Requirements for HEVC: Comparing H.265, H.264, and MPEG-2" by John Pallett, Director of Product Marketing for Enterprise Products at Telestream, a company that provides video capture, encoding, transcoding, and network-based delivery. The testing he discussed was based on SD and HD content, not UHD, but the findings should apply similarly."
