nDVR Live Streaming:

nDVR Provide viewers the best experience: pause, play & rewind live video streams or watch later. Deliver enhanced live stream control to viewers on any device.

also allows you to record a live stream media server broadcasts it to viewers with DVR playback controls (play, pause, rewind). Wowza nDVR will records the stream as it’s ingested so that it remains available for HTTP-based playback after the live stream ends, or you can convert the nDVR stream (called a store) to MP4 for VOD sharing and viewing.

Record and archive live video streams with Wowza software and enable nDVR for enhanced viewing experiences.
nDVR live streaming software enables you to record a live stream while simultaneously enabling users to play or pause the live stream, rewind to a previously recorded point, or resume viewing at the current live point over the Adobe HDS, Apple HLS, and Microsoft Smooth Streaming.

Compared to client-specific implementations, nDVR significantly reduces cost by minimizing network storage requirements and simplifying the delivery workflow.

To ensure the highest-quality playback across mobile, web and streaming devices, more video professionals are adopting HTTP-based adaptive bitrate streaming technologies.
In recent history, Apple’s HTTP Live Streaming (HLS) has been more widely supported across devices than development for advanced MPEG-DASH functionality has been throughout the industry—even with adoption by Netflix, Facebook, YouTube and others.

MPEG-DASH is already recognized as an international standard and is central to the Hybrid Broadcast Broadband TV (HbbTV) 2.0.1 specification, which is leveraged in deployments all across Europe.
With the new update, application providers and broadcasters who already use MPEG-DASH for delivery can now implement these advanced playback features and create code-agnostic applications using a variety of formats.

What’s more, by supporting advanced nDVR functionality for both HLS and MPEG-DASH, we’re paving the way to ensure future support of Common Media Application Format (CMAF): a new streaming format geared toward cheaper and easier over-the-top (OTT) delivery.

DVR: Live recording and MPEG-DASH playback

DVR feature set which allows recording incoming live streams and provide playback via MPEG-DASH and HLS.

Streaming MPEG-DASH Video-on-Demand as origin server

  • Both H.264/AVC and H.265/HEVC codecs are supported.
  • Supports MP4 video+audio, video, audio, original MP4, Apple QuickTime extension.
  • MP4 transmuxing to DASH in VOD mode. MP4 is effectively re-packaged with low resource usage.
  • Remote HTTP storage support allows to effectively stream files, those size exceeds available file system capacity.
  • Adaptive bitrate is available via SMIL files support.

    DVR features are:

  • Recording the specified incoming streams.
  • Playback of previously recorded streams.
  • Playback for selected time range for EPG etc.
  • Time-shifted playback of recorded stream.
  • Time line browsing and playback.
  • Split recording by threads and recording location.
  • High performance and low resources usage.
  • Source stream timing errors handling.
  • nDVR Add on has options for DVR modes such as Append ,Version and Delete.
