■ Local Keyboard
Used to change the language mapping of your browser machine running the Remote Console
Applet. Normally, the applet determines the correct value automatically. However, depending on
your particular JVM and your browser settings this is not always possible. A typical example is a
German localized system that uses an US-English keyboard mapping. In this case you have to
change the Local Keyboard setting to the right language, manually.
■ Hotkeys
Opens a list of hotkeys defined before. Choose one entry, the command will be sent to the host
system.
A confirmation dialog can be added that will be displayed before sending the selected command to
the remote host. Select “OK” to execute the command on the remote host.
■ Encoding
These options are used to adjust the encoding level in terms of compression and color depth. They
are only available unless “Transmission Encoding” is determined automatically (see the Section called
Transmission Encoding in Chapter 3).
Compression Level:
You may select a value between 1 and 9 for the desired compression level with level 1 enabling
the fastest compression and level 9 the best compression. The most suitable compression level
should always be seen as a compromise between the network bandwidth that is available, on your
video picture to be transferred, and on the number of changes between two single video pictures.
We recommend to use a higher compression level if the network bandwidth is low. The higher the
compression level the more time is needed to pack and unpack the video data on either side of the
connection. The compression quality depends on the video picture itself, e.g. the number of the
colors or the diversity of pixels. The lower the compression quality, the more data have to be sent
and the longer it may take to transfer the whole video picture.
If level 0 is chosen the video compression is disabled, completely.
The option “Video Optimized” has its advantages if transferring high-quality motion pictures. In this
case the video compression is disabled, completely and all video data is transferred via network as
full-quality video snippets. Therefore, a high amount of bandwidth is required to ensure the quality
of the video picture.
