Hello, everyone!
I'd like to share with you the process of implementing video quality monitoring.
The process is as follows:
1.After a fault occurs in the video service of a residential user, the user reports this fault to the carrier.
2.The carrier's maintenance personnel exclude communication faults after checking the head end system or performing an Internet Group Management Protocol (IGMP) emulation test.
3.The maintenance personnel enables video quality monitoring using the OLT or U2000.
Video quality monitoring can be enabled on Upstream transmission boards, PON boards, or ONTs.
NOTE: If video quality monitoring is enabled on an uplink port, only the quality of inbound video streams can be monitored. If video quality monitoring is enabled on a non-uplink port, only the quality of outbound video streams can be monitored.
•To monitor the quality of an IPTV program, specify a multicast VLAN and multicast address.
•To monitor the quality of a VoD program, specify the source and destination IP addresses of this program, destination IP address, destination port, and transmission protocol.
4.The OLT or U2000 issues a command for enabling video quality monitoring to each monitoring point. After receiving this command, these monitoring points configure hardware based on the program information carried in the command. Then, the hardware captures video streams, adds timestamps to them, and sends the video streams to the CPU for the monitoring indicator calculation.
5.The CPU sends calculated results to each monitoring point in real-time, and the monitoring points periodically report these results to the control board of the OLT.
6.Video quality monitoring stops when the preset monitoring duration times out or the maintenance personnel disable this function.
7.The maintenance personnel obtains monitoring results from the OLT or U2000.
8.The maintenance personnel demarcates the fault based on monitoring results.
9.The maintenance personnel rectifies the fault.
Thanks.
