CLIPSTER Hardware Guide
2.3.2 Digital Video I/Os
This section contains some further information about the digital video
in- and outputs of CLIPSTER.
Generally DVS names the input/output channels (connectors/ports) of
the digital video signals alphabetically: the main video stream is then
available, for instance, on port A and the secondary video stream on
port B. However, because some systems offer more channels providing
sometimes different functions, the labeling of the ports can be supple-
mented by numbers (e.g. ’1/A’, ’2/B’, etc.). To simplify matters when-
ever feasible the main video ports (ports A) may be labeled without an
alphabetical or numeric structuring.
For YUV you will usually use one channel (the main video ports, mostly
labeled ’A’, single link). For YUVA you will need two channels (’A’ for
YUV and ’B’ for the key signal). With RGB you will always need two
channels (’A’ and ’B’, dual link).
On CLIPSTER the input ports can be switched in software between
port A and port C in single-link video modes, and ports A/B and C/4 in
dual-link modes. With this you can directly connect two input sources
to the system and no extra source switch is required.
During an output the ports C and 4 (dual link; in single link port C only)
mirror the output of the channels A/B. The SD-only ports provide at all
times a (down-converted) output in YUV SD. Additionally, these signal
outputs (ports C, 4 and SD-only) can be provided with customizable in-
formation superimposed on the image (’burn-in’ feature, e.g. with
timecode, keycode, comments, etc.). All other output channels, i.e.
no. 5 to 8, are available during an output in special rasters only (e.g.
special 4K rasters, tiling of 4K image to quad HD-SDI).
slot panel connectors The slot panel connectors of CLIPSTER pro-
vide, for example, the video I/O panel con-
taining video connections and the graphic card
panel. Furthermore, if applicable, some addi-
tional panels may be present for internal rea-
sons or on customer request. More details
about the slot panel connectors can be found
in section “Slot Panel Connectors” on
page 2-18.
power supply The redundant power supply provides the sys-
tem with power. It consists of several indepen-
dent power supply units: Even if one fails the
others will still supply enough power to keep
the system operational. Further information
about the power supply can be found in sec-
tion “Power Supply” on page 2-21.
