Time-Stamping And Latency

An important consideration for the live data products is that, in order to synchronise views with other content on the screen, it should be time-stamped so that it can be synchronised with playback. This should also enable support for DVR functions such as rewind and pause.

 

Apart from functional requirements (e.g. instant on-demand replay), SCOOP & SPOON considers the non-functional requirements in live streaming solutions as key:

  • Low end-to-end latency
  • Perfect sync of video, audio and metadata, based on timestamps
  • Instant channel changes (cross-channel synchronisation, e.g. OTT and TV viewers)
  • Massively scalable, millions of concurrent users
  • Load balancing, control and orchestration
