I am troubleshooting an IPTV Layer 3 multicast VPN across a 10GB MPLS network.
Only certain HD channels are experiencing severe freezing and tiling; all other SD and HD channels work fine. Our IPTV video monitoring equipment is detecting and reporting packet loss by monitoring a continuity counter. I have asked every equipment vendor we have and read every .pdf I can find and no one seems to know exactly:
- How/when/where an MPEG transport stream continuity counter fits into a transport stream ?
- What packets/frames in the transport stream are being counted?
- Why does the reported packet loss seem to occur in increments of 16 (0, 16, 32) ?
- How can there be an error condition with 0 packet loss ?
- How/when/where does the PCR value fit into the transport stream ?
