The video pre-processor provides spatial/temporal noise reduction which is motion adaptive.

Vertical Blanking Interval (VBI) Data
General
All VBI information carriage are configurable (either enabled or disabled). The video line from which the VBI is extracted is
configurable. The default is set according to the recognised standard for the VBI type.
VBI Lines
Up to at least 8 VBI lines per field can be extracted. Unless otherwise stated, all VBI data are formed into one VBI transport stream
packet that conforms to ETSI EN 301 775 or SCTE 127.
VBI Data
Data can be extracted from the vertical blanking interval of the incoming video stream, processed, and then included in the output
transport stream.
The following is a summary of the VBI Data functionality available from the unit.
VBI Data on a Separate PID
The VBI data is packetised within MPEG-2 PES packets as specified in ETSI ETS 300-472 (teletext), ETSI EN 301 775 or SCTE 127
for all other VBI data.
Refer to Transport Stream Output > VBI Data on a Separate PID for more information.
Closed caption data, and aspect ratio signalling can also be inserted in to the compressed video elementary stream.
Timing
The VCM aligns VBI data and compressed video frames within the bounds dictated by time stamping of received data, i.e. stamp the
same PTS on the video and VBI that came in on the same frame.
HD Ancillary Data Processing
General
Impairment Reduction Comments
Noise Reduction (motion adaptive)
Only available if license VP/SWO/HD/MCTF has
been purchased.
Component Comments
Video Index It is possible to extract video index and another VBI type from the same line.
Closed Captions
Via line 21 & 284 (CEA-608C) or SMPTE 334 (extracted from VANC data - 525
Line only).
Teletext Up to 18 lines can be extracted per field.
