port+2 and so on until the requested number of ports is used and it shall then revert to the
base port for the next splice_request.
The port_selection_descriptor( ) may be utilized in any Splice_Request command that has a
hardware config with Logical_Multiplex type 0x0006 to alter the default operation of the
ports.
The port may be any valid unicast or multicast IPv4 Address:Port combination. The splicer
shall perform an IGMP join on a multicast IP.
Logical_Multiplex – If the Port carries multiple Insertion Multiplexes on a single input,
then this field allows the Splicer to determine which to use when splicing from this Server.
The meaning and format of this field is defined by the Logical_Multiplex_Type field. In the
event that a non-standard definition for the Logical_Multiplex is required, the
Logical_Multiplex_Type shall be set to 1 for User Defined.
Type 0x0007 – IPV6 Address with Single Program Transport Stream (SPTS) support
Type 0x0007 is utilized by VOD and Ad Servers where remapping of PIDs is impractical or
undesirable. In these cases it is desirable to use a SPTS per UDP Port.

number_of_destination_ips – Specifies how many dest_ip_address(s) follow. The valid

dest_ip_address - The IPV6 address that the splicer shall use for the content associated with
the splice.
