Video Formats
The following video formats are supported for composite inputs:
• NTSC/RS-170
−
Standard for 60 Hz video signals. In this format,
the video input is a single analog signal. A video frame is
displayed as 640 x 480 lines.
• PAL
−
Standard for 50 Hz video signals. In this format, the video
input is a single analog signal. A video frame is displayed as 768
x 576 lines.
The Y/C format is supported for S-video inputs. In this format, the
video input is provided as two separate analog signals. The Y signal
contains luminance information (the gray scale portion of the color
image). The C signal contains chrominance information (the color
portion of the image). For 60 Hz, a video frame is displayed as 640 x
480 lines. For 50 Hz, a video frame is displayed as 768 x 576 lines.
Videos Input Channels
The DT3153 provides three video input channels that you can use as
follows:
• Three composite video inputs, connected to channels VID0_IN,
VID1_IN, or VID2_IN; or
• One S-video input and two composite video inputs. For the
S-video input, connect the Y signal to channel VID1_IN; connect
the C signal to the CHROM_IN channel. You can then connect
composite video inputs, if desired, to the two unused video input
channels.
Through software, the video multiplexer on the board determines
which channel or channels are digitized. By default, channel 0
(VID0_IN) is selected.
