![]() Greater efficiency means video can be shown at the same quality while consuming less bandwidth, or bandwidth can be maintained to achieve greater quality. Related: Could BPG be the successor to JPEG? If codec A and codec B both display the same image quality, but the size of A’s file is twenty percent smaller, then A is more efficient. The less data a codec can use to display an image without degrading its quality, the more efficient it is. This leads to an inevitable question: If it’s been working for so long, and is compatible with virtually every device consumers own today, why replace it? Image used with permission by copyright holderĮfficiency is the answer. It was finalized all the way back in 2003 and really started to catch on a few years later. H.264 is an incredibly popular codec that forms the basis of most online video shown today. It’s the most popular way to encode video to HEVC, but it’s not the only choice. TV: Why a TV could be your next gaming monitorĪnd what about x265? That’s the open-source encoding project, not the standard. ![]() The standard was defined by the Moving Picture Experts Group (MPEG) and the Video Coding Experts Group (VCEG), and each calls it by a different name, but the standard is the same. Each is a different name for the same codec. So, what’s the difference between H.265 and HEVC? There isn’t one. Image used with permission by copyright holder Video encoding isn’t defined by the standard.” This is why there are many different video encoders, and some are more efficient than others. “When you define a codec, the only thing really defined by the spec is the syntax of the compressed video stream, and the method to decode it. Tom Vaughan, the Vice President of product management and marketing at MultiCoreWare, developer of the open-source x265 encoder, clarified this. Interestingly, a video coding standard doesn’t define how video is encoded into a file. The codec helps your computer understand how a stream of data can be displayed as a video file rather than gobs of randomly distributed colors. It’s basically the video equivalent of a. H.265, or High Efficiency Video Coding, is a new video coding standard that specifies how to decode video. ![]() What is H.265, and how is it different from HEVC? 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. There’s no reversing this trend video is going to become more popular, and it will consume more bandwidth. Established players like Netflix are upping their game to 4K and networks that traditionally haven’t had a place in video, like Facebook, are embracing it. The ever-increasing volume of video content is due to a perfect storm of rapidly increasing demand and quality. The networking giant Cisco estimates it consumed about 70 percent of all online traffic in 2014, and that share will rise to between 80 and 90 percent by 2018.
