Nimble Advertizer: server-side ads insertion for Icecast

Our online audio streaming customers often face the need for monetizing for their online radios and live podcasts. This should be done on a server side to provide best user experience and avoid ad-blockers usage.

Today Softvelum introduces Server-Side Ads Insertion (SSAI) framework for Nimble Streamer, it's called Nimble Advertizer. This framework allows dynamically insert personalized ads into live streaming content.

Advertizer key features are:

  • Pre-roll ads per each connection
  • Flexible timing setup for mid-roll ads
  • Per-stream ads insertion business logic
  • Personalized ads

Nimble Advertizer may use all input live protocols supported by Nimble Streamer, they are Icecast and SHOUTcast, RTMP, RTSP, SRT, UDT, HLS and MPEG2TS.
Live input codecs are AAC and MP3. Notice that with our Live Transcoder you may also use MP3, MP2, Speex, PCM G.711 (a-law, μ-law)
For your ads source files you may use AAC and MP3 codecs.

Output live stream protocol is Icecast - this is the most popular protocol for online radios.

The workflow is easy to adopt within any business logic

  1. Nimble Streamer media server processes incoming streams to get audio content
  2. Nimble Advertizer calls your handler web application to get business logic description
  3. Advertizer gets files with advertisements to process them via Nimble Streamer according to your logic defined via handler
  4. Nimble inserts the ads into original media and packages it into Icecast protocol
  5. End user connects to Nimble and gets audio stream containing original content mixed with advertisements
  6. Playback is running smooth regardless of ads insertion over time in any player which supports Icecast.
