iPtv transmission modes
uniCast transmission (faCtory default)
At unicast transmission up to 4 clients are supplied with each one station.
When logging in, each client will be assigned to a tuner, whose signal is then
streamed only to this client (unicast). Therefore in menu "Antenna" –> section
"LNB Auto-setting" the check box "automatic frontend allocation" must be
activated (page 19).
—> The number of streams for a smooth playback is dependent on the
dynamic data rates that are transmitted by the broadcasters.
Proper operation of this option also depends heavily on the perform-
ance of the connected network and the clients (particularly for HD
streams).
multiCast transmission
At multicast transmission the IPTV streams are streamed via a multicast IP ad-
dress to the network – without a particular target. Any number of clients can
receive these streams by selecting the IP address (and the related port). The
stations, which are streamed, are defined by a multicast list, which must be
uploaded to the DSI 400 (page 27).
—> The number of streams for a smooth playback is dependent on the
dynamic data rates that are transmitted by the broadcasters.
Proper operation of this option also depends heavily on the perform-
ance of the connected network and the clients (particularly for HD
streams).
We recommend a maximum of 4 HD or 6 SD streams.
Therefore in menu "Antenna" –> section "LNB Auto-setting" the check box
"automatic frontend allocation" must be deactivated (page 19).
The configuration of the multicast transmission is to be done via menu
"MenuRTSP" (page 25).
