256kbps and you're on a shared connection, then choosing a lower FEC setting of 20%-33% may
give you better results.
Conserving Bandwidth with FEC
There is a trade-off between the quality and the reliability of an IP connection – particularly when
FEC is activated on your codecs. However, it is possible in certain situations to configure different
FEC settings on each codec to match connection bandwidth capabilities at either end of the link,
conserve bandwidth and create more stable IP connections.
For example, if your broadcast is a one-way broadcast from a remote site, i.e. you are not using
the return path from the studio, or only using it for communications purposes, it is possible to
reduce or turn off FEC at the studio codec. This effectively reduces the bandwidth required over
the return link and increases the overall bandwidth available for the incoming broadcast signal
from the remote site.
17.8 Configuring Encode/Decode Direction
By default the codec is configured to encode and decode data. However, it is possible to encode
or decode audio data only. This is useful for:
· Conserving connection bandwidth when unidirectional data streaming is required.
· Lowering data costs.
· Increasing overall connection reliability.
To use this feature configure the transmitting codec to encode only and the receive codec to
decode only. To adjust this setting:
1. Press the HOME button to return to the Home screen.
2. Use the navigation buttons on the front panel to select Connect and press the button
3. Select IP and press .
4. Select your preferred IP Session mode and press the button.
5. Use the down navigation button to select Setup and press .
6. Navigate to Dir and press .
7. Select Encode Only or Decode Only and press .
