Wowza (a technology behind DukeStream) showed a number of exciting new features released with version 3.1 of their media server. Besides their own booth, they had a table at the Microsoft booth to announce their new support of Azure which will allow applications using the Microsoft media engine to use Wowza servers to deliver their content.
The Wowza nDVR AddOn a live-stream cache that stores content in a normalized format accessible to Wowza Media Server 3 for playout to deliver live linear streams as time-shifted content. Wowza nDVR also supports trick-play features such as live-stream pause, rewind, and resume, and enables content publishers and service providers to develop the kind of premium catch-up TV services that both enhance and individualize the viewer experience.
The Wowza Transcoder AddOn’s audio-only option gives users the ability to pay a significantly lower “audio-only” price when using the Wowza Transcoder AddOn with streams that do not contain video.
New Dynamic Transcoder Overlays allow customers to use compositing to overlay text, images, motion graphics, and secondary video sources instantly onto streams passing through the Wowza Transcoder AddOn. The feature can be used in many cases, including the dynamic insertion of advertising, titling, sporting event scores, and picture-in-picture video. It also allows single-display viewing of multicamera broadcast and surveillance feeds on any screen. Dynamic Transcode Overlays can be manually configured or pre-programmed based on external events, making this a powerful new tool for adding premium TV-like experiences at commodity prices.
In another move to help advance media delivery, Wowza Media Systems has also become a member of the MPEG-DASH Promoters Group (DASH-PG), an industry consortium working to promote the adoption of the MPEG-DASH standard in the market. Wowza joined DASH-PG in an effort to help avoid fragmentation of the multimedia HTTP streaming market – one of the major challenges facing content and service providers today. DASH-PG believes the use of this open international standard for multimedia delivery over Internet will accelerate market growth; enable interoperability between content preparation tools, servers, CDNs, and end devices; and reduce the cost of delivery.
