NGS-XXX
NGS boards are used to convert and encode video or data sources to JPEG2000 streams, which are provided to
the video network. One NGS consists of a processing board, which is visible on the front and of a connection
board, which is accessible on the rear.
The active processing board performs data conversion and provides visual feedback about the operation of the
board by means of the LEDs on its front plate. The passive connection board provides connectors for video input
and streaming output. For detailed information on usage and technical specifications of the NGS boards; please
refer to the individual user manuals; see section
1.5 Online manual
.
3.2.1
General interfaces and control elements
The processing boards have multiple LEDs at the front panel. The number of the LEDs depends on the type of the
NGS. The LED far left is the status LED. Its function is identical for all NGS types. It also provides feedback on the
operation the NGC-105.
The connection board is on its right part equipped with board specific connectors. In the left part at the very left
edge there are two RJ45 connectors for the connection to the video net. The exact position of these two connec-
tors may vary slightly on different NGS types. They are labeled
STREAM
or
STRM
