The ‘Time Between Packets’ (TBP) parameter is directly related with the packet
size and therefore with the occupied bandwidth (overhead) and delay. Therefore,
the appropriate value for this parameter is a trade off between delay and
bandwidth.
In order to achieve the minimum delay between encoder and decoder it is
necessary that the transmission time between packets is minimum as well.
However, the greater the TBP, the less bandwidth is required (less overhead),
but the more delay there will be in the connection. Otherwise, the smaller the
TBP, the smaller the packet size, and the greater the overhead, due to the IP
headers in the packets. With this tool, the user can know beforehand the
required bandwidth, overhead, packet size and delay for the current compression
mode and TBP value.
When the packet size needs to be fragmented, keep in mind that the overhead
changes for that reason. When it happens it is indicated as follows:
