Transfer IPTV Signal To All Sites Along The Ring?

My topology is a physical ring, and I need transfer IPTV signal to all site along the ring.For example:

A (headend)--- B --- C --- D
|______________________|
Note: -----: have spoke-mesh defination
_____: no spoke-mesh defination to prevent loop

So, with MPLS/VPLS I can implement it. With spoke and mesh defination, the traffic can transfer form A to B, C or D as drop-continute action in ring topology (between different VC). Everything is good, FRR can work very fast. But when the topology have a failure link, for example the link between B and C, at that time the traffic will go from A to B then B come back to A and A --- D ---C. This action is so stupid, because it can increase delay, jiiter in network. On the other hand, when the node failure ( B failure), C will loss the IPTV signal, even the link from A--D--C always good.
