The encoding service, C21 Live Cloud Encoder, can generate multiple qualities (adaptive bitrate) in multiple formats (transmuxing) from a single source of audiovisual content.


The option of a private cloud enables a  user to make use of the virtualized software as part of his own hardware resources, in order to have access to a cloud solution at the location of acquisition tothe point of broadcasting content, minimizing the initial investment.


C21 Live Cloud Encoder offers all the benefits of Cloud Computing applied to streaming:


  • Encoding resources optimization: the option of activating only what is needed and at the same time changing the amount of encoding resources in real-time, opens an opportunity to new encoding projects in which the inversion would be, otherwise, impossible.
  • CAPEX/OPEX optimization: All the integration possibilities in a mixed encoding platform (appliance, SaaS and cloud).
  • Cost reduction: logistics, remote management, monitoring by region.
  • Global reach: encoding resources are available in different areas of the world.
