Please explain wrr and srr priority queue differences

Can someone please explain the difference in behavior between SRR and WRR priority queues? I have read so much and I still don't understand. In both, SRR and WRR, is the priority queue serviced until empty (thus starving the other queues?) Or is it... in WRR, the priority queue uses strict priority thus starving the other queues until it's empty while in SRR, you can specify a threshold guaranteeing bandwidth for the priority queue, that when exceeded, the switch moves on to the next queues (thus not starving the other queues as frames would be building up in the priority queue while the other queues are serviced?)
