Simulcast

Hi
I am trying to implement live streaming and given the following response for requesting a DRM stream:
   “response”: {
       “stream”:null,
       “drm”: {
           “playready”: {
               “licenseAcquisitionUrl”:“{some server url}/playready/RightsManager.asmx”,
               “token”:“{some token}”,
               “stream”:“https://{some some url}/bitrate1.isml/live.mpd”           }
       },
How do I use this data to populate the Video Content object?

All help appreciated.

Thanks Andy
