Video signal connections
Technical developments have vastly changed the types of video signals and thus the video connections. Using the appropriate Hama
cables and adapters allows you to connect even the most diverse jacks together and to make the proper cable connection.
i
Analogue signals:
Din AV connection
- 6-pin plug-in connection
- Transmitted is:
Video signal in FBAS format
Audio signal in stereo
Switching voltage for playback
RCA connection (composite)
- 2-pin plug-in connection:
Inner conductor is the signal line, outer
conductor is always the shielding
- Video signal in FBAS format; yellow marking
Analogue signals:
Scart connection
21-pin universal socket for video signals,
switching voltage and data – depending
on the socket wiring, the video signal is
transmitted in:
- FBAS format or
- S-video format or
- RGB format or
- YUV format
AV Cables
BNC connection
- 2-pin plug-in connection:
Inner conductor is the signal line, outer
conductor is always the shielding
- Video signal in FBAS format
- Used for home theatre and by professionals
S-Video/Hosiden/Mini Din connection
- 4-pin plug-in connection:
2 conductors for brightness signal (Y signal/
luminance) with sync signal, 2 conductors
for colour signal (C signal/chrominance)
- Video signal in S-video format
YUV connection (components)
Three RCA or BNC plug-in connections:
Type of signal: YUV
Green: Brightness signal (Y signal)
Blue: Colour – difference signal B-Y
also: called U/Ph/Cb
Red: Colour – difference signal R-Y
also: V/Pr/Cr
Wide YUV:
Especially wide-band (at least 150 MHz) and
high-quality signal levels are required for the
high resolution of HDTV.
RGB connection
RG s B Red green blue signal with sync
signal on green (RGB – sync on
green)
RGB-Y Red green blue signal with sync
signal on separate 4th line.
A normal Y-signal can also be
used as sync signal
Also often called RGB-Y/S,
RGB-H/C or sRGB signal
RGB-HV Red green blue signal with separate
horizontal and vertical sync signal
on separate 4th and 5th line
15-pin HDD connection
The HDD 15 connection is used for PC
monitors and very often for beamers.
These beamers mostly have an input switch
with video signal converter (sync stripper)
so that they can process PC as well as video
signals. Only then it is possible that they can
process – according to the internal beamer
wiring – VGA signals from the PC sector
as well as analogue video signals (FBAS,
S-video, YUV or RGB).
The VGA signal PC signal (analogue RGB
+ HSync + VSync; full picture transmission)
from the PC sector is not compatible to the
RGB video signal (analogue RGB + H/V sync
+ semi-picture transmission)!
DVI-A (12+5) connection
This plug is only suitable for the transmission
of VGA signals (analogue RGB + H-Sync
+ V-Sync); pin assignment of data lines for
monitor identification.
PJ multi connection/D4 etc.
Video signals are often hidden in HDD15 or
special manufacturer-specific jacks.
These interfaces can contain video signals in
various formats: FBAS, S-video, RGB and YUV
depending on the assignment.
