Software Support

Net-X-Code Server

medianxs logo approved

Net-X-Code Server captures into side bar SCC (608 SD) or MCC (708 HD) text files if closed captioning is available.  SMPTE 436M is also captured, if recording a compatible MXF file type.  MOV closed caption track capture is also available, with a custom DDRConfig setup.

Net-X-Code Server also supports 608 and 708 insertion into the vertical blank area, if "Use Vertical Blank" is enabled.  Net-X-Code Server can read the MCC/SCC files, as well as MPEG-2 user closed caption (ATSC), Avid embedded, SMPTE 436 and MOV closed caption tracks.

These interfaces can also display the 608 or 708 captions to the VGA video preview area for confidence monitoring
