Avoiding Overload Conditions 

The VBrick 9000 series H.264 encoder has numerous configuration options and under some 
configurations may overload the host processor. This is indicated by the Operational Mode 
reporting an "overload" on the Monitor > System page. Transport Streams and TCP clients 
are more CPU intensive than RTP and UDP clients. CPU loading can be decreased by 
reducing some or all of the following: Target Bit Rate, number of streams, transmitters, and 
clients. Another option is to increase the Max Packet Size on the Encoder Configuration > 
Global page but proceed with caution as this may cause issues in some IP networks and with 
some players.
