4.2.5 SMPTE-325M Configuration
Figure 4-10.SMPTE-325M Configuration page
The SMPTE-325M Configuration page defines the flow control protocol to be used
between the MENCAP 50 and a multiplexer for opportunistic data broadcast.
SMPTE-325M can be implemented over ASI (return channel) or over Ethernet. CEFD
has chosen to implement SMPTE-325M over Ethernet, since Ethernet is more prolific
and should operate with any manufacturer’s multiplexer.
Opportunistic Data Insertion (ODI) places data packets into the output multiplexer to fill
any available free bandwidth. The multiplexer requests additional MPEG-2 Transport
packets from the MENCAP 50 as buffer becomes available.
Enable
The “Enable” SMPTE-325M Boolean allows the user to enable or disable the SMPTE
325M option.
Port to Listen On
The UDP port that will be opened on the MENCAP 50 to listen to SMPTE-325M ODI
messages from the multiplexer.
PID to Expect
The PID (number) returned from the multiplexer encapsulated in an IP packet in the form
of a SMPTE-325M ODI packet.
