DT-421D module is a converter from ASI to IP that allows linking an IP network to a MPEG-2 ASI network. Each one of the services or even the input TS is packaged in an IP / UDP or IP / RTP / UDP stream, with an IP address (Multicast) and an UDP port specified by the user.

SPTS outputs operating mode.
It is a converter from ASI to IP multicast SPTS streams. The module assigns a multicast IP to each one of the selected services. The result is delivered at the Ethernet output so each service is a multicast SPTS TS-IP, up to 40 (10 per ASI).

MPTS outputs operating mode.
Four streams multicast MPTS TS-IP come out from the Ethernet output, containing the same services and DVB-SI tables as the TS-ASI input.
