Why the Broadcasting Industry Should Get Behind DASH Adoption
How is DASH different from competing video standards. It's open, and for broadcasters that's a big factor. At the recent 流媒体 East conference, Jeff Tapper, chief architect at 数字灵长类动物, taught attendees how to build a DASH player, and also why DASH stands apart.
"The real key differentiator of DASH, as opposed to any of the other HTTP streaming formats, is it's an open standard. HLS, HDS, Smooth Streaming: They're all owned by one company," Tapper said. "Some of them have become 事实上的 standards on their own, but the more I work with broadcasters and people who are used to open standards like AM and FM and UHF and VHF -- these are standards that everybody agrees on. The broadcasting world loves standards."
Not only is DASH open, it's also open to any video codec.
"Most of the other standards I've talked about were built with H.264铭记在心. 这是 事实上的 standard at the time, and so they're build around that," Tapper explained. "DASH was built to be codec-agnostic. DASH doesn't care what the content is. 真的, all DASH is is a way of segmenting your MP4 files and describing where to find those segments. Those MP4 files, whether you've encoded them with H.264或H.265, VP6, VP8, VP9, it doesn't matter."

How To: Building a DASH Video Player
As the MPEG-DASH standard grows in popularity, a common question is “Where are the players to consume DASH content?在这次会议上, we will explore how to consume DASH content, including parsing the manifest, retrieving the segments, choosing appropriate bitrates, and playing back the content. This session will focus on playback natively in a browser without plugins, but is also applicable to Flash, 安卓, 和iOS开发者.
