Response:
VBICFG RESPONSE
Verbose- "OK\r\n" to acknowledge receipt of command, or
"ERROR- [Description]\r\n" if error, ending command
Terse- "0\r\n" to acknowledge receipt of command, or
"[NON-ZERO NUMERIC VALUE]\r\n" if error, ending command
"\r\n" concludes modify responses (empty line)
Examples:
Get current line number for captions of CVBS
*.DCMD VBI CVBS CAPTIONS
LineNumber= 21
Set line number to 9 for captions on SDI
*.DCMD VBI SDI CAPTIONS 9
Notes:
For captions to be output, the line number must be set and the type
must be set. See DCC for more information.
AFD and SCTE104 are only supported on SDI and SDIALT.
Line 21 waveform captions are supported on CVBS, SDI, and SDIALT. For CVBS, any valid line other than 0 will enable line 21 waveform captions for both CVBS and SDI outputs (SD-SDI). The line number will be returned as line 21. Digital Ancillary Captions, SMPTE 334M, are supported on both SDI and SDIALT, the line number range is from 7 to 22.
Note: Simultaneous Waveform and digital ancillary captions will be output on SD-SDI ports if both CVBS and SDI line numbers are configured. When SDI is set to 'DISABLED' and CVBS set to '21', Waveform line 21 only captions will be present on SD-SDI outputs.
Waveform Teletext is supported on CVBS, SDI, and SDIALT. For CVBS, any valid line other than 0 will enable waveform teletext for both CVBS and SDI outputs (SD-SDI). The line number will be returned as line 22.
Digital ancillary teletext, OP47, is supported on SDI and SDIALT. For SDI and SDIALT, the line number range is from 7 to 18.
Note: Simultaneous Waveform and OP47 Teletext will be output on SD-SDI ports if both sets of line numbers are configured. When SDI is set to 'DISABLED' and CVBS set to '22', Waveform Teletext only will be present on SD-SDI outputs.
VITC is not supported at this time.
An error will be reported if a set or get is attempted on an incompatible value set.
Example, setting afd line number for CVBS.
setting teletext line number for SDI.
