Note: With the Real Time Network Analyzer, the user can get information
about the jitter during the audio connection in real time. For more
information about this, please refer to chapter IX.6.7 – Proprietary
protocols v2.
2. The audio interruptions could be due to a reduction on the bandwidth in the
IP connection. With the 'Test Streaming' tool from the web page, the user
can measure the download and upload bandwidth between two Prodys IP
Codecs. Once the user knows the available bandwidth, it is possible to select
the proper bit rate for the compression mode.
The user can obtain information about the delay of the encoder/decoder
process for any particular mode, and the actual bandwidth which will be
required for that mode, from the web page, in the 'audio' tab. Besides, in
the non-block modes, like PCM or apt-X, it is possible to modify the size of
the frames from 2 to 24 msc. In the rest of the modes, this size is fixed and
determined by the corresponding standard. The larger the block size, the
higher the delay, but the smaller the required bandwidth (more efficient use
of IP packets), and vice versa.
