From the FEC Scheme drop-down list, choose the FEC packet sending arrangement
(Block Aligned or Non-Block Aligned) and click Apply . They are defined in the pro-
MPEG FEC and SMPTE-2022 standards.
Note: If the FEC Mode in the FEC Settings is set to None , the FEC Scheme is
ignored. For more information on FEC Mode , see Configuring Forward Error
Correction Settings (on page 248).
FEC Scheme Description
Block Aligned Column FEC packets are set by using an interleaver.
Non-Block Aligned Each FEC packet receives L packets after the last related data
packet.
Setting the PCR Controls and Output Ports
Note: This is for the D9854 only.
1 In the MPEG over IP Output page ( Transport Stream > MPEG over IP Output ),
refer to the Advanced PCR Controls section.
2 From the Start Ethernet Frame on PCR drop-down list, choose whether to
always transmit a new IP packet when a new Program Clock Reference (PCR)
arrives (Yes or No).
3 In the Output Port Selection section, choose the MPEG over IP output mode in
the Port Selection drop-down list. Select None to disable the MPEG over IP
interface. Select Data Port to always output data on the Data port. Select Control
Port to always output data on the Management port.
4 The IP Version field displays the IP protocol. We currently support IPv4 only.
5 Click Apply .
Setting Up the MPEG over IP Auto Synchronization Options
The MoIP Auto Sync area allows you to configure the DPM without editing each
output channel and PID separately.
1 In the MPEG over IP Output page ( Transport Stream > MPEG over IP Output ),
refer to the MoIP Auto Sync area.
2 From the Enable Auto Fix for Collision drop-down list, choose Yes for the DPM
to resolve channel and PID collisions automatically on the transport outputs.
New values are assigned to the parameters that caused the conflict. The new
assigned values are not used by any incoming transport or other PE outputs. If a
collision is detected, you can review the new changes and click Apply to accept
the new changes.
Choose
No and a detailed list of all the conflicts is displayed in the Output
Channel and PID Conflicts table (click View Conflicts ) when a conflict occurs.
You can then resolve the conflicts manually.
