5-3. HD to SD (with Genlock)
This operation example shows how to convert HD-SDI video to SD-SDI video with using a
genlock signal. The 16:9 HD video is converted to 4:3 SD video by
horizontally filling
a 4:3
screen (letter box type). . The output video is synchronized with the genlock signal. Adjust the
genlock phase in the menu.
Connection
1) Connect the OSD OUT port to NTSC (PAL) monitor.
2) Input an HD-SDI signal to the [INPUT-3G/HD/SD] port.
3) Connect the [OUTPUT-3G/HD/SD 1] port or [OUTPUT-3G/HD/SD 2] port to a waveform
monitor or an SDI monitor.
4) Input a genlock signal (BB) to the UFM frame.
5) Power on the UFM frame.
Conversion Setting
1) Press the MENU OSD button to display the menu on the NTSC (PAL) monitor.
