necessary access rights.
Transmission Encoding
The Transmission Encoding setting allows changing the image-encoding algorithm that is
used to transmit the video data to the Remote Console window. It is possible to optimize
the speed of the remote screen depending on the number of users working at the same
time and the bandwidth of the connection line (Modem, ISDN, DSL, LAN, etc.).
Automatic detection
The encoding and the compression level is determined automatically from the
available bandwidth and the current content of the video image.
Pre-configured
The pre-configured settings deliver the best result because of optimized adjustment
of compression and colour depth for the indicated network speed.
Manually
Allows to adjust both compression rate and the colour depth individually. Depending
on the selected compression rate the data stream between the IP-KVM switch and
the Remote Console will be compressed in order to save bandwidth. Since high
compression rates are very time consuming, they should not be used while several
users are accessing the IP-KVM switch simultaneously.
The standard colour depth is 16 Bit (65536 colours). The other colour depths are
intended for slower network connections in order to allow a faster transmission of
data. Therefore compression level 0 (no compression) uses only 16 Bit colour depth.
At lower bandwidths only 4 Bit (16 colours) and 2 Bit (4 gray scales) are
recommended for typical desktop interfaces. Photo-like pictures have best results
with 4 Bit (16 gray scales). 1 Bit colour depth (black/white) should only be used for
extremely slow network connections.
