Description
XStream IP
™
DVB-S2
• IP-over-DVB encapsulation. Supports the
transmission of IP packets with/without Ethernet
frames over DVB-S2/DVB-S2X using Multiprotocol
Encapsulation (MPE) (EN 301 192), Unidirectional
Lightweight Encapsulation (ULE) (RFC 4326) and
Paradise XStream Encapsulation (PXE).
• ACM. Enables DVB-S2/DVB-S2X Adaptive Coding
and Modulation (ACM).
• VCM. Allows either two ASI streams, or one ASI
stream and one IP stream, to be multiplexed onto a
single carrier.
