Note: Regarding SAP (Session Announcement Protocol)
IPv4 global scope sessions use multicast addresses in the range 224.2.128.0 - 224.2.255.255 with SAP
Announcements being sent to 224.2.127.254 Port 9875 (note that 224.2.127.255 is used by the
obsolete SAPv0 and MUST NOT be used).
IPv4 administrative scope sessions using administratively scoped IP multicast. The multicast address
to be used for SAP announcements is the highest multicast address in the relevant administrative
scope zone.
For example, if the scope range is 239.16.32.0 - 239.16.33.255, then 239.16.33.255 is used for SAP
Announcements.
We assume, that this professional unit is used by professional technicians knowing all relevant norms,
regulations, abbreviations (i.e. DVB, ATSC, …) and specifications.
