Das ist der Text vom Playout, bitte anpassen.

Please consider these points while configuring a Playout of Closed Captions.

  • We only support devices from AJA for CC playout.
  • To be able to pass through CC data embedded into the Live Signal, an AJA Kona 4 is needed.
  • CC of the Live Signal may be on lines 9 through 20. The incoming signal is automatically scanned for caption data.
  • Playing out QuickTime MOV Videos, line-21 burn-in, the CC data track as well as MCC and SCC sidecar files are supported for Closed Captions.
  • When playing out MXF Videos, sidecar files in both SCC and MCC formats are now supported for Closed Captions. This includes files written by just:in.
  • When both a sidecar file and QuickTime/XDCAM CC data track are available for a Video, the sidecar file will be used.
  • When playing out NTSC HD with Closed Captions enabled just:out always sends CEA-708 CC packets. For media with CEA-608 CC packets these will be wrapped into CEA-708 CC packets.
  • When playing out NTSC SD with Closed Captions enabled just:out now always sends CEA-608 CC packets. For media with CEA-708 CC packets these will be wrapped into CEA-608 CC packets whenever possible.
  • Using the Jump to Next function can take some seconds before the captions will be cleared on screen.
  • CEA-608 and CEA-708Closed Captions can be added directly to the outgoing RTMP stream. Please verify with your CDN that CC are supported.

Types of captions

Two types of captions are available: EIA-608 and EIA-708.

  • EIA-608 is for SD only. It is read directly from Line 21 of the picture data (=1st visible line. Note the white "blocks" in the picture - these are encoded closed captions). It is being extracted from the picture and written as a closed captioning track into the QuickTime movie.
  • EIA-708 is for HD only. It is read from VANC Line 9, which is not a visible line. It is directly copied as SMPTE334M packet into the closed captioning track of the QuickTime movie.

If you see the CC logo, Just In recognizes closed captions and they will be recorded into the QuickTime movie automatically

Setup

No special setup required. If Just In recognizes closed captions, it will display the "CC" logo in the GUI.

Supported Hardware

As for now the following configurations are supported:

  • SD NTSC: Both AJA and Blackmagic in both 8 and 10 Bit.
  • HD NTSC: Blackmagic in 10 Bit only, AJA in both 8 and 10 Bit.
