9064 Functional Description
1-8 9064 PRODUCT MANUAL 9064-OM (V4.1)
Scaler Function
The scaler function provides up, down, and cross-conversions between
multiple standard SD and HD video formats, multiple frame rates, film frame
rates, and cross-conversion between interlaced and progressive formats. Table
1-1 lists the 9064 conversion choices available for various input formats and
frame rates.

Notes: 1. The drop-down list choice of “Same as Input” is used when no conversion is desired. For clarity, it is not redundantly listed here.
2. “X” denotes conversions not available or invalid conversions.
3. Interlaced formats rates listed are field rates. Progressive format rates listed are frame rates.
4. If the original material does not have a proper 3-2 cadence suitable for conversion to film rates, the conversion reverts to standard
de-interlacing. While this video can be converted to film rates, the resulting image motion will lack smoothness. Therefore, make
certain interlaced video is appropriately constructed for 3-2 reverse pulldown when converting video to film rates. See 3-2
Pulldown Conversion and Considerations (p. 1-11).
5. Formats using a 30/29.97 Hz progressive frame rate can be converted to a 24/23.98 Hz progressive frame rate, however some
image motion irregularity will appear in the converted output.
6. “NTSC” and “PAL” in this manual informally denote 486i5994 and 575i50 SD-SDI video formats.
