DM240XR High-Speed Digital Modulator
User Interfaces
MN-DM240XR– Revision 12
4–12
PCR RESTAMPING:
{ON, OFF}
This selection is available only when the Advanced ASI
Interface Type is selected. When set to “On,” the DM240 will
overwrite the PCR Value in appropriate packets to compensate
for any Null Packets, which have been inserted into the data
stream.
The Transmit Clock (SCT) supplied by the DM240XR is always Output.
Normally, this clock is used to clock the data out of the data source and then
return it to the SCTE input. The DM240XR is then set to SCTE mode
eliminating any possible clock skew. Alternately, the data source can
generate the SCTE clock internally and the SCT signal can be ignored. If
SCT mode is selected, the Modulator data clock will not be locked to the
incoming data stream. This mode is NOT recommended except for testing or
fault backup.
4.3.3.2
Ethernet Interface (J1)
The PIIC Ethernet Data Interface (EDI) is a full duplex 100/1000 Base-T supported by an RJ45
connector. The EDI supports the input of generic UDP packets (Bridge Mode) or Pro–MPEG
COP3 formatted packets. With the Pro-MPEG input, a powerful video-specific packet-based
forward error correction (FEC) algorithm is also available providing a cost-effective solution for
error recovery in video streams transported over public or private IP networks.
BRIDGE MODE
In Bridge Mode, the interface accepts all valid Ethernet packet types and sizes.
ETHERNET DATA INTERFACE, ADDITIONAL MENUS
When the Ethernet Data Interface is installed, it will add new menus for control and status
monitoring. It is recommended that all Ethernet parameters be selected prior to placing the unit
into the network.
