UDC-163 User Manual

(V 1.2)

Four copies of SD analog composite and SD-SDI are generated and sent to four, 2x1 switches (S7, S8,
S9, S10) that allow the user to select either analog composite or SDI for the outputs (BNCs 7, 8, 9, 10).

Available Format Conversions

The UDC-163 has extensive re-format and down conversion capabilities. It can act as a
downconverter, ARC and frame rate converter. The format conversions are listed in the chart below.

Notes:

1. All rates translated to effective frame rates, interlaced rates “ i ” are two times the number shown.

For example, i 29.97 is 59.94 fields per second (two fields per frame thus the interlaced frame rate
is 29.97); but progressive “ p ” 29.97 is 29.97 frames per second.

2. SD active line rates are PAL (575) and NTSC (486).

3. The UDC-163 cannot accept native 720 p23.98 or sF23.98, however it can convert those signals if

they are delivered inside a p59.94 transportation wrapper (as typically done with this format) and
processed as p59.94.
