Introduction
9061-OM (V4.9)
When output video is set to 720p for either SD or HD video, the 720p output
can be converted to 720p half-rate formats as listed in Table 1-1. When output
video is set to 1080 film (1080p23.98) for either SD or HD inputs, the 9061
can convert the output to 1080PsF23.98 (segmented frame progressive). Both
of these functions can be independently applied to either SD and/or HD video
inputs.
The scaler function also provides aspect ratio conversion that provides a
choice from several standard aspect ratios. Additionally, user defined and
"Follow AFD Settings" conversion can be applied. User defined settings
allow custom user-defined H and V aspect ratio control. "Follow AFD
Settings" sets the output aspect ratio to track with AFD (Active Format
Description) settings embedded in the received video signal.
Timecode Processor
(See Figure 1-2.) This function provides for extraction of timecode data from
the input video, and in turn re-insertion of timecode data into the output SDI.
In this manner, timecode data can be preserved, even after format conversion.
The function can monitor analog and SDI video streams for supported
timecode formats and then select and prioritize among analog VITC, SDI
VITC, SDI ATC_VITC, and SDI ATC_LTC. If the preferred format is
detected, the preferred format is used by the card; if the preferred format is
not detected, the card uses other formats (where available) as desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
Option
+LTC
between VBI formats over SDI and audio LTC, as well as RS-485 LTC.
Audio LTC can be received or sent over a selected balanced analog audio
input, or as digital audio over a selected embedded or AES input.
