More interesting than IW10 on CDNs, "Service C" (which must be Vudu) streams at 9M! The RMCAT evaluation criteria should include testing with competing DASH flows (Vudu for fireworks bigger than those in Vancouver).

hi matt,

thanks for the interesting pointer.

at page 2, note 2 says "services that control both the server and the client (eg youtube)..."

do you have a reference to this youtube feature? The Web client for YouTube is written in Javascript. It's controlled by the service. The CDN for YouTube is also controlled by the service.

I don't think the reference is to any particular YouTube feature.

regards, saverio
