Set up traffic shaping
If you're streaming to 10/100 Mbps set-top boxes over Gigabit Ethernet and you notice frames are
dropping, you can limit the bandwidth of the stream, see
.

Audio and video use nearby port numbers (<port number>and <port 2>). The
minimum distance between audio and video ports must be 2.

Set up traffic shaping
If you're multicasting to set-top boxes that have 10/100 Mbps interfaces on the same Gigabit Ethernet and
you notice frames are dropping, you can limit the bandwidth of the stream using traffic shaping to adapt
for the lower bandwidth set-top boxes. Only multicast streams support traffic shaping: MPEG-TS USP,
MPEG-TS RTP/UDP, and RTP/UDP.
If traffic shaping was previously setup using the API, we recommend switching to this method
of setting traffic shaping using the Admin panel. If traffic shaping is currently setup using Pearl
Mini's API, see the Technical Notes for your Pearl Mini model for instructions. They're available
from the product resources page on the
website.
When traffic shaping is enabled, the default bitrate limit is set to auto. In auto mode, the bitrate is limited
to the sum of the channel's configured bitrate plus 4 Mbps and is adjusted to fit within the range of 4
Mbps minimum to 95 Mbps maximum.
