Multicast Server versus Multicast Client Programs
Two different types of multicast programs need to be created when multicasting:
·
A multicast server program is used by the broadcasting codec to send multicast IP packets
to multicast routers on a network.
·
A multicast client program is used by codecs to receive multicast IP audio packets.
A multicast server codec sends audio packets only and a multicast client codec receives audio
packets only. Codecs using the client program request multicast packets (sent from the server
codec), which are distributed by multicast routers.
Creating Multicast Server Programs
Important Notes:
Before you start program configuration please note:
·
Ensure all connection related settings like the port, algorithm, bit rate (etc) match on
both multicast server and client programs or they will not connect successfully.
·
You cannot edit a program when it is currently loaded in the codec.
·
You can
lock a loaded custom program
in a codec to ensure the currently loaded
program cannot be unloaded by a codec dialing in with a different type of program.
·
Some drop-down menus and settings may be greyed out intentionally depending on
features available.
·
It is possible to save a program at several points throughout the program wizard and
use default settings to save configuration time.
·
To learn more about programs see the section titled
About Program Dialing
.
·
Always dial the multicast server codec connection first before connecting multicast
client codecs.
·
Multicast client codecs will display return link quality (LQ) only. The
Return
reading
represents the audio being downloaded from the network locally. Multicast server
codecs do not display LQ readings.
·
The default UDP audio port setting is 9000 for the first multicast, 9010 for the second
multicast and 9020 for the third multicast. The client and server port settings must
match to receive an audio stream. E.g. if a client codec wishes to receive multicast
audio stream 2 then it must use audio port 9010.
·
Forward Error Correction (FEC) is not available for multicast connections.
·
It is not possible to send auxiliary data using multicast connections.
·
Use firmware higher than 2.8.xx in the Bridge-IT, Genie and Merlin families of codecs to
transmit auxiliary data.
·
It is not possible to connect to a G3 codec and receive multicast IP audio streams.
·
