HD Closed Captioning
Digital Television Closed Captioning (DTVCC) can be displayed on the monitor wall, allowing visual
monitoring of decoded text from an HD-SDI video source. The lines of text that are part of the video source
metadata are displayed within the corresponding video window.
Dolby E/AC-3 Metadata
Metadata ( Dialnorm and Program config ) information contained in a Dolby E audio stream can be exposed
on the monitor wall in text form. Dolby E and PCM audio levels can be displayed via audio meters.
Alternatively, the Dolby E metadata can be embedded as ancillary data (VANC) in the video stream.
For example:
• If multichannel audio (up to 8 channels) is coded in a Dolby E stream and transported over a single AES
channel, metadata and audio levels are extracted from the Dolby E stream:
• Limited to 1 embedded audio source, selectable, no ABT support
• VU and Peak meters (8 channels), for each source
• Program config, for each source
• Dialnorm for program 1, for each source
• If multichannel audio (up to 16 channels) is transported as regular AES channels (up to 8) in the SDI
embedded audio, metadata is extracted from VANC packets:
• Program config
• Dialnorm for program 1
• VU and Peak meters come from the AES in PCM
