Introducing - Adaptive Streaming
Published on: Jan 10, 2017
With the newest release of Delight VR one of the most requested features is now available: Adaptive Streaming. With adaptive streaming your users will always enjoy a fast startup time and high-quality video playback according to their available bandwidth. Similarly you can save CDN bandwidth and thus cost by only transferring those video segments that are actually played back on the user’s side.
Delight VR supports both most used adaptive streaming protocols, MPEG-DASH and HLS for maximum compatibility and integrability into your existing workflow. As of now you can use MPEG-DASH and HLS sources for 2D, 3D, 360° Video and 180° Video monoscopic and stereoscopic formats using our <dl8-video> element. Additionally you can display MPEG-DASH and HLS streams within our virtual cinema environment.
Adaptive Streaming is at the core of any fast and reliable video delivery solution in the Web: Users want to experience fast startup times of videos and want to always experience the best quality that can be delivered given their bandwidth requirements. This is where Adaptive Streaming shines. In contrast to progressive video the seeking times also rapidly decrease as the video is segmented into smaller chunks that can be efficiently selected for decoding and result in less wasted decoding overhead when seeking.
From a content delivery standpoint, both DASH and HLS provide the most future proof technologies in terms of possible quality output from one source and minimizing overall outgoing bandwidth and thus costs on your CDN. It is also the stepping stone in any content-delivery architecture towards live-streaming and new advanced features we’ll be showcasing soon, e.g. foveated streaming for high-quality next-level VR video content delivery.

- Encoding Service
Providing a performant encoding pipeline and reliable delivery for HLS and DASH compatible streams can be a daunting task. That’s why we will offer an encoding service that does the heavy lifting for you. With a simple dashboard and a programmable API it will integrate in all workflow needs you might have.
- Live streaming
Live streaming is the next market for VR video delivery. Switching to Delight VR Adaptive Streaming right now, leaves you prepared for the next big thing in VR as the technologies are the technical prerequisite for VR live streaming.
- Foveated Streaming
VR Video is sometimes bemoaned due to its perceived “low quality”. This is due to the fact that 360° (or 180°) of video (possibly stereoscopic) have to be compressed into a single HD or 4k video stream. Foveated streaming approaches solve this problem by providing high-quality streams at those regions of the user’s field of view, where it is most required: The so called fovea region. This means higher quality content, can be streamed at roughly the same bandwidth requirements as with a normal pipeline. Delight VR’s aforementioned Encoding Service will be providing support for a high-quality foveated rendering approach. DASH and HLS Adaptive Streaming protocols are the gateway to becoming compatible to the future of high-quality next-level VR Video streaming.
