V.1.4.2. Tx
Audio: This option allows the user to configure the audio transmission
parameter (TBP: Time between packets) and to know in advance, the required
bandwidth and delay of the connection.
IP: This option allows the user to configure some IP header fields to carry out
QoS.
Audio
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. In other words, 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.
