9064-OM (V4.1) 9064 PRODUCT MANUAL 1-9
Introduction
9064 Functional Description
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 9064
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 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 the SDI video input of the card for supported
timecode formats, and then select and prioritize among SDI VITC, SDI
ATC_VITC, and SDI ATC_LTC timecode sources. 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 received timecode
formats and provides insertion, line number control, and re-formatting to
SDI VITC, ATC_VITC, and/or ATC_LTC timecode output formats.
