Closed Captioning (CC), Teletext, AFD, and Safe Area Compliance

With Option DATA installed, this instrument can monitor for CC data (including
V-Chip ratings) present in the selected signal and display that data overlaid on the
Picture display. (CEA 608 (VBI), CEA 608 (ANC), CEA (608/708), CEA 708,
TeletextB (VBI), TeletextB OP47 SDP (ANC), and TeletextB OP47 Multi (ANC)
closed caption transports are supported.
Your instrument can also display Safe Action and Safe Title graticules, allowing
you to monitor for incorrect placements of graphics, logos, and other branding
elements. This will help you ensure that those items do not obscure text or
essential action. SMPTE, ITU, and ARIB TR-B.4 standards are supported.
