Yes absolutely. Reading the VANC data from an SD-SDI or HD-SDI stream (that includes Closed Captioning data) is often of great help – it is necessary in order to verify CC, to monitor things like AFD or Broadcast Flag, to capture VANC info such as CC data to a separate file, etc.

Vela Research has solutions, one of which is called ArgoNavis, geared to monitoring, verifying and/or capturing VANC data from SDI streams.
